Abstract (sommario):

Full-field quantitative visualization of multiphase flows requires the introduction of high resolution noninvasive methods. Two such methods are presented: Scanning Confocal Microscopy (SCM), and Magnetic Resonance Imaging (MRI). SCM has higher resolution, contrast, and depth discrimination than conventional light microscopy. A modern SCM system operating in reflection mode performs optical sectioning of 3D surfaces with submicron resolution at video rates, and this suggests its use in reconstructing evolving interfaces. MRI is a versatile tool for mapping the distribution of liquids (primarily water) in 3D space and for performing multicomponent velocity measurements. MRI is the only practical solution in systems that are strongly refracting or opaque to visible light. SCM is employed (for the first time) to image frost growing under ambient conditions, and MRI is used to visualize phase change and to measure local velocity in natural convection in water-saturated porous media. These problems reflect the research interests of the author but also serve to show the potential of the techniques in probing multiphase flows containing complex interfaces.

Abstract (sommario):

CSIRO Minerals has developed a Multiphase Flow Meter (MFM) for measuring oil, water and gas flow rates in offshore topside and sub-sea oil production pipelines. In 1997 Kvaerner Oilfield Products (KOP) signed an exclusive licence agreement with CSIRO Minerals for production and further development of the dual energy gamma-ray transmission (DUET) MFM. This new technology has the potential to save the oil industry many millions of dollars in capital, operating and maintenance costs. Essentially, the MFM consists of two specialised gamma-ray transmission gauges, pressure and temperature sensors, which are mounted on a pipe spool carrying the full flow of the well stream, and processing electronics. Measurements of the intensities of transmitted gamma rays are made to infer the proportions of oil, water and gas, and flow velocities are determined from cross-correlation of gamma-ray signals.Prototype MFM's have completed several Australian and overseas trials, including an extended four-year trial (1994–1998) on Esso's West Kingfish platform in Bass Strait and Texaco's test loop facility in Humble, Texas. During these and other trials the MFM has determined water cut to accuracies of 2–4%, and liquid and gas flow to accuracies of 5–10%, up to a gas volume fraction (G VF) of 95%. Full production versions of the MFM are presently under construction by KOP, and the first installation is due to take place early in 2000 at Texaco's Captain oilfield in the North Sea. CSIRO Minerals is presently consulting with the Australian oil industry to assess interest in the development of a wet gas MFM, capable of operating at GVF's in excess of 95%

Abstract (sommario):

The oil and gas industry’s goal of developing high performing multiphase flow metering systems capable of reducing costs in the exploitation of marginal oil and gas reserves, especially in remote environments, cannot be over emphasised. Development of a cost-effective multiphase flow meter to determine the individual phase flow rates of oil, water and gas was experimentally investigated by means of low cost, simple and non-intrusive commercially available sensors. Features from absolute pressure, differential pressure (axial), gamma densitometer, conductivity and capacitance meters, in combination with pattern recognition techniques were used to detect shifts in flow conditions, such as flow structure, pressure and salinity changes and measured multiphase flow parameters simultaneously without the need for preconditioning or prior knowledge of either phase. The experiments were carried out at the National Engineering Laboratory (NEL) Multiphase facility. Data was sampled at 250 Hz across a wide spectrum of flow conditions. Fluids used were nitrogen gas, oil (Forties and Beryl crude oil – D80, 33o API gravity) and water (salinity levels of 50 and 100 g/l MgSO4). The sensor spool piece was horizontally mounted on a 4-inch (102mm) pipe, and the database was obtained from two different locations on the flow loop. The ability to learn from ‘experience’ is a feature of neural networks. The use of neural networks allows re-calibration of the measuring system on line through a retraining process when new information becomes available. Some benefits and capabilities of intelligent multiphase flow systems include:  Reduction in the physical size of installations.  Sensor fusion by merging the operating envelopes of different sensors employed provided even better results.  Monitoring of flow conditions, not just flow rate but also composition of components.  Using conventional sensors within the system will present the industry with a much lower cost multiphase meter, and better reliability. Comment [HS1]: I think this word should be measured to make the sentence read correctly.

Abstract (sommario):

In process industries such as for example the oil and gas industry, the paper pulp industry, and the mining industry, multiphase flows are common. It is often of interest to measure the mass fractions of the different phases. In for example the mining industry, iron ore powder is transported using water, and there is a need of measurement techniques to monitor the particle mass fraction. Most existing techniques are either invasive, inaccurate, or too slow to be used in an on-line manner. The long-term goal of this research project is to develop a method for measuring mass fractions and mass fraction velocities, using ultrasound. The first two papers in this thesis consider how scattering of sound can be measured, and how this can be used to measure mass fractions. The ideas are verified with experiments. The third paper is on optimal experimental design. The problem is selecting suitable experiments from a large candidate set. We present a new algorithm for generating optimal designs. The methods in the first two papers can be extended to incorporate more of the underlying physics, as well as using more sophisticated multi-dimensional signal processing techniques.

Abstract (sommario):

Severe slug flow is one of the most undesired multiphase flow regimes, due to the associated instability, which imposes major challenges to flow assurance in the oil and gas industry. This thesis presents a comprehensive analysis of the systematic approach to achieving stability and maximum production from an unstable riser-pipeline system. The development of a plant-wide model which comprises an improved simplified riser model (ISRM) required for severe slug controller design and control performance analysis is achieved. The ability of the ISRM to predict nonlinear stability of the unstable riser-pipeline is investi¬gated using an industrial riser and a 4 inch laboratory riser system. Its predic¬tion of the nonlinear stability showed close agreement with experimental and simulation results. Through controllability analysis of the unstable riser-pipeline system, which is focused on achieving the core operational targets of the riser-pipeline produc¬tion system, the maximum stable valve opening achievable with each controlled variable considered is predicted and confirmed through the simulation results. The potential to increase oil production through feedback control is presented by analysing the pressure production relationship using a pressure dependent dimensionless variable known as Production Gain Index (PGI). The performance analyses of three active slug controllers are presented to show that the ability of a slug controller to achieve closed loop stability at large valve opening can be assessed by the analysis of the H∞ norm of the comple¬mentary sensitivity function of the closed loop system, T(s) ∞. A slug controller which achieves the lowest value of the T(s) ∞, will achieve closed loop stability at a larger valve opening. Finally, the development of a new improved relay auto-tuned slug controller algorithm based on a perturbed first-order-plus dead-time (FOPDT) model of the riser system is achieved. Its performance showed that it has the ability to stabilise the riser system at a valve opening that is larger than that achieved with the original (conventional) algorithm with about 4% increase in production.

Abstract (sommario):

The development of oil and gas fields in offshore deep waters (more than 1000 m) will become more common in the future. Inevitably, production systems will operate under multiphase flow conditions. The two–phase flow of gas–liquid in pipes with different inclinations has been studied intensively for many years. The reliable prediction of flow pattern, pressure drop, and liquid holdup in a two–phase flow is thereby important.With the increase of computer power and development of modelling software, the investigation of two–phase flows of gas–liquid problems using computational fluid dynamics (CFD) approaches is gradually becoming attractive in the various engineering disciplines. The use of CFD as a modelling tool in multiphase flow simulation has enormously increased in the last decades and is the focus of this thesis. Two basic CFD techniques are utilized to simulate the gas–liquid flow, the Volume of Fluid (VOF) model, and the Eulerian–Eulerian (E–E) model.The purpose of this thesis is to investigate the risk of hydrate formation in a low–spot flowline by assessing the flow pattern and droplet hydrodynamics in gas– dominated restarts using the VOF method, and also to develop and validate a model for gas–liquid two–phase flow in horizontal pipelines using the Eulerian– Eulerian method; the purpose of this is to predict the pressure drop and liquid holdup encountered during two–phase (i.e. gas–oil, gas–water) production at different flow conditions, such as fluid properties, volume fractions of liquid, superficial velocities, and mass fluxes.In the first part of this thesis, the VOF approach was used to simulate the droplet formation and flow pattern at various levels of liquid patched and restart gas superficial velocities. The effect of restart gas superficial velocity on the liquid displacement from the low section of the pipe showed a decrease in the remaining liquid with an increase in gas superficial velocity, and the amount of liquid depends on the fluid properties, such as density and viscosity. Moreover, the flow pattern is also strongly dependent on the restart gas superficial velocity as well as the patched liquid in the low section. A low gas superficial velocity with different patched liquids illustrated no risk of hydrate formation due to the observed flow pattern that is often a stratified flow. However, as the restart gas superficial velocity is increased, regardless of initial liquid patching, hydrate formation is more likely to be observed due to the observed flow pattern, such as annular, churn or dispersed flow.In the second part, the E–E model was employed to establish a computational model to predict the pressure drop and liquid holdup in a horizontal pipeline. Due to the complicated process phenomena of two–phase flow, a new drag coefficient was implemented to model the pressure drop and liquid holdup in the 3D pipe. Different simulations were performed with various superficial velocities of two–phase and liquid volume fractions, and were carried out using RNG k-ε model to account for turbulence. Based on the results from the numerical model and previous experimental study, the currently used E–E model is improved to get more accurate prediction for the pressure drop and liquid holdup in horizontal pipes compared with the existing models of Hart et al. (1989) and Chen et al. (1997).The improved model is validated by previously reported experimental data (Badie et al., 2000). The deviation of pressure drop and liquid holdup obtained throughout the CFD simulation with regard to the experimental data was found to be relatively small at low superficial gas velocities. It was observed that the pressure gradient increased with the system parameters, such as the drop size, liquid and gas superficial velocity and the liquid volume fraction, where the liquid holdup decreased.The developed model provided a basis for studying the pressure drop and liquid holdup in a horizontal pipe. Different parameters have been examined, such as gas and liquid mass flux and liquid volume fraction. Two empirical correlations have been examined (Beggs and Brill (1973), and Mukherjee and Brill (1985)) against the CFD simulation results of pressure drop and liquid holdup, it was noted that they gave better agreement with the air–oil system rather than the air–water system, but shows reasonable agreement over the entire gas mass fluxIn the third part, the coupling of Eulerian–Eulerian multiphase model with the population balance equation (PBE), accounting for droplet coalescence and breakage, is considered. Strengths and weaknesses of each numerical approach for solving PBE have been given in details. The Quadrature Method of Moments (QMOM) is used and particular coalescence and breakup kernels were utilized to demonstrate the droplet size distribution behaviour. Numerical simulations on a two–phase flow in a horizontal pipe, including coalescence and breakage are performed. The QMOM is shown to give the solution of the PBE with reasonable agreement. The numerical data are compared with the experiment data of Simmons and Henratty (2001). The flow variables, such as liquid volume fractions, gas and liquid superficial velocities are employed to examine the droplet size distribution and the potential of the multiphase k–ε with population balance model for predicting the two–phase pressure drop and liquid holdup.The significance of this work is to assist in understanding the risk of hydrate formation in bend pipes at gas–dominated restarts with different patched liquid values. The knowledge gained from this work can be utilized to avoid the hydrate formation operating conditions. The developed of multiphase flow E–E model will provide an accurate prediction for two–phase pressure drop and liquid holdup in a horizontal pipe which will be of benefit to the design of tubing and surface facilities.

Abstract (sommario):

The work described in this thesis was aimed at developing the understanding of two regimes in vertical gas-liquid flow in tubes, namely annular flow and churn flow. In annular flow, there is a continuous gas passage at the centre of the pipe with a film of liquid travelling upwards at the wall. Part of the liquid phase in annular flow may be entrained as droplets in the core gas flow. In churn flow there is also a gas core (which the present work has shown to be continuous) and a liquid film; however, the flow direction of the liquid in this film varies with time. Thus, the liquid flows upwards in large waves on the surface of the film; between the waves, the film may change direction and flow downwards towards the next wave. Such flows are extremely complex and there are aspects of their behaviour which are poorly understood. In the work described in this thesis, several areas have been studied. Disturbance waves are of central importance in annular flows. Such waves are characterised by their large amplitudes relative to the mean film thickness, their high translation velocities relative to the mean film speed, and their circumferential coherence (i.e. their 'ring-like' structure when fully developed). An important part of the present work was concerned with the existence, development and translation of disturbance waves in upwards, gas-liquid annular flows. At very low liquid flow rates, disturbance waves are not formed (and, as other work has shown, the entrainment of droplets from the liquid film is negligible). In the present work, multiple conductance probe units have been employed to study the growth and development of disturbance waves. From the results, it is found that disturbance waves begin to appear and to start to achieve their circumferential coherence from lengths as short as 5-10 pipe diameters downstream of the liquid injection location; this coherence gradually strengthens with increasing distance from the inlet. It is further shown that the spectral content of the entire interfacial wave activity shifts to lower frequencies with increasing axial 3 distance from the inlet, with the peak frequency levelling off after approximately 20 pipe diameters. Interestingly, on the other hand, the frequency of occurrence of the disturbance waves first increases away from the inlet as these waves form, reaches a maximum at a length between 7.5 and 15 pipe diameters depending on the flow conditions, and then decreases again. This trend becomes increasingly evident at higher gas and/or liquid flow-rates. Both wave frequency measures increase monotonically at higher gas and/or liquid flowrates. Important evidence regarding the mechanisms of disturbance waves and the associated droplet entrainment can be obtained by the axial view photography technique. This technique is described in Chapters 3 and 6. The technique was used to visualise the wave characteristics, in particular of the two entrainment mechanisms (bag break up and ligament break up mechanisms) proposed previously by Azzopardi (1983). The axial view photography technique provided visual evidence for the existence of the two mechanisms, although in contrast to Azzopardi's findings, both break up mechanisms were observed to occur simultaneously. The axial view photography technique was also used in the present work to provide further insights into the inception of disturbance waves. It was found that the initiation mechanism for disturbance waves was the occurrence of a disturbance at a given location around the tube periphery. This is consistent with the idea of a link between turbulent burst phenomena and disturbance waves first proposed by Azzopardi and Martin (1986). The initial disturbance links up with similar disturbances to ultimately form the characteristic ring-like structure characteristic of fully developed disturbance waves. In churn flow the present work concentrated on three aspects: The use of axial view photography to explore the continuity of the gas core in churn flow. The development (in collaboration with two other research students - Deng Peng and Masroor Ahmad) of a correlation for entrainment rate and hence entrained fraction in churn flow. Measurements of 4 pressure gradient and holdup in churn flow, from which an average wall shear stress can be deduced. In the first task, it was shown (it is believed for the first time) that there is a continuous path for the gas phase near the tube axis. In churn flow the behaviour of entrained fraction is extremely complex and conventional methods for measuring it are no longer valid. Barbosa etal (2002) studied entrainment in churn flow using iso-kinetic sampling probes and the correlation referred to above was based on this data. The correlation has been widely used in predicting the entrained fraction at the transition between churn and annular flow. Since the direction of flow of the liquid film near the channel wall fluctuates, it is difficult to estimate the instantaneous value of wall shear stress. However, if measurements are made of total pressure gradient and liquid holdup, then the mean value of wall shear stress can be estimated. This procedure was pursued by Govan (1990) who used mechanically operated quick-closing valves to measure holdup. In the current work, a new measurement technique was utilised, namely quick closing pinch valve which offer a great accuracy and are easy to install. Pressure gradient and hold up data were collected over a wide range of gas and liquid flowrate. An averaged wall shear stress was then calculated based on these measurements. At higher liquid mass flow rates, the results were in good qualitative agreement with those of Govan (1990) but (at lower mass fluxes) anomalies occur which need further investigation.

Abstract (sommario):

A finite element model is developed for multiphase flow through soil involving three immiscible fluids: namely air, water, and an organic fluid. A variational method is employed for the finite element formulation corresponding to the coupled differential equations governing the flow of the three fluid phase porous medium system with constant air phase pressure. Constitutive relationships for fluid conductivities and saturations as functions of fluid pressures which may be calibrated from two-phase laboratory measurements, are employed in the finite element program. The solution procedure uses iteration by a modified Picard method to handle the nonlinear properties and the backward method for a stable time integration. Laboratory experiments involving soil columns initially saturated with water and displaced by p-cymene (benzene-derivative hydrocarbon) under constant pressure were simulated by the finite element model to validate the numerical model and formulation for constitutive properties. Transient water outflow predicted using independently measured capillary head-saturation data agreed well with observed outflow data. Two-dimensional simulations are presented for eleven hypothetical field cases involving introduction of an organic fluid near the soil surface due to leakage from an underground storage tank. The subsequent transport of the organic fluid in the variably saturated vadose and ground water zones is analysed.

Kanshio, Sunday. "Multiphase flow in pipe cyclonic separator". Thesis, Cranfield University, 2015. http://dspace.lib.cranfield.ac.uk/handle/1826/9847.

Testo completo

Abstract (sommario):

In the petroleum industry, cyclonic separators are acceptable as hydrocyclone, mist eliminators, separator internal device and compact metering package. Weight and small footprint requirements for applications such as subsea separation, downhole separation, and compact gas monetization systems is driving interest in using cyclonic separator for bulk gas-liquid separation. Unfortunately, the challenge of coping with the effect of unsteady inlet flow behaviour on the separator performance limit it acceptance for bulk gas-liquid separation. Fundamental understanding of the flow behaviour inside the separator under various inlet flow conditions is required to deal with the challenge. While most published work have addressed flow behaviour in the lower half of cyclonic separator, this thesis concentrated on the upper half. A gas-liquid pipe cyclonic separator was setup at Cranfield University for bulk gas-liquid separation. Large amount of data at the inlet and upper part of the separator were acquired using electrical resistance tomography (ERT), wire meshes sensor (WMS), conductivity hold up probe and pressure transducers. The acquired data were used in analysing flow regimes, upward swirling liquid film (USLF), zero-net liquid flow (ZNLF), liquid holdup and, general separator performance. It was found from analysis of USLF data that a maximum USLF height exists for every constant superficial liquid velocity. A correlation based on dimensionless numbers was proposed for predicting this height. Experimental results on ZNLF showed that a critical ZNLF also exist above which liquid carryover can take place. The liquid holdup for this critical ZNLF was measured under separator operating condition using ERT and a correlation for predicting the liquid holdup was proposed. Four flow regimes were identified as swirling annular, light-mist heavy-mist and churn using visual observations, ERT, WMS and pressure transducer. A flow regime map was proposed based on gas and liquid Froude number. The performance based on the operating envelope for liquid carryover and pressure drop for horizontal and 270 downward inclined tangential inlet was compared. It was concluded that the separation performance was marginally improved by using an inclined tangential inlet. The pressure drop for the inclined inlet was far greater than that of horizontal inlet. Two inlet nozzles with D–shape were used for separation enhancement. The nozzle that reduces the diameter of full pipe bore by 25% gave slight improvement but also gave the greatest pressure drop. The nozzle that reduced the full pipe bore diameter by 50% performed poorly.

Abstract (sommario):

This report contains data that demonstrates the scaling of flow regime, pressure drop, and holdup multiphase flow with pipe diameter. In addition, entrance length effects, the onset of liquid entrainment, and interfacial shear modeling at high gas density were studied for purposes of validating multiphase flow design methods. Stratified, slug and annual flow regimes were observed in a 112-foot long 3.5-inch diameter test section. Air, freon, and water were used to represent pipeline fluids.
