The article is devoted to the problem of complex processing of oil feedstock and increasing the output of light petroleum products, in particular, catalytic cracking gasoline. Currently, the oil refining industry of Kazakhstan is faced with the task of complex processing of hydrocarbon raw materials, increasing the depth of processing and output of light petroleum products. In this connection it is urgent to solve the problem of lack of raw materials for oil refineries of the Republic of Kazakhstan.

At the moment, there is a situation in the world in which the volume of proven reserves of light oils is decreasing, and the volume of reserves of heavy oils are increasing. The processing of heavy hydrocarbons is becoming more complicated and does not provide the necessary depth of extraction of light distillates. Large capital expenditures are required to ensure the specified oil refining depth parameter.The deepening of oil refining is developing through the development and implementation of flexible technological schemes and advanced high-intensity environmentally friendly thermocatalytic

This work presents a one-dimensional (1D) model for simulating the behavior of an FCC riser reactor processing bio-oil. The FCC riser is modeled as a plug-flow reactor, where the bio-oil feed undergoes vaporization followed by catalytic cracking reactions. The bio-oil droplets are represented using a Lagrangian framework, which accounts for their movement and evaporation within the gas-solid flow field, enabling the assessment of droplet size impact on reactor performance. The cracking reactions are modeled using a four-lumped kinetic scheme, representing the conversion of bio-oil into gasolin

Abstract Residue Fluid Catalytic cracking (RFCC) is a valuable subset of the more conventional Fluid Catalytic cracking (FCC) process that generates most of the world’s gasoline pool. The critical distinction of RFCC involves the processing of “dirty” atmospheric residue (AR) directly from crude distillation and not just the more conventional use of relatively pure gasoil feedstocks. By direct catalytic cracking of “dirty” residue the refiner benefits economically by avoiding a whole intermediate process, namely vacuum distillation.

Abstract In recent years much attention has been focused on the use of hydrogen water chemistry (HWC) to control the electrochemical corrosion potential (ECP) of stainless steel in boiling water reactors (BWRs) to mitigate intergranular stress corrosion cracking (IGSCC) of sensitized 304 stainless steel (SS). It has been demonstrated that improving the surface catalytic activity of structural materials results in low ECPs below -230 mVshe for IGSCC protection under stoichiometric excess H2, even at high O2 levels. It was shown that a low ECP was achieved by lowering the oxidant concenteration

Abstract Several experiences (successful and unsuccessful) with the use of titanium heat exchangers in refining processes are summarized. These experiences primarily involve distillation column overhead condensers in atmospheric crude distilling units, fluid catalytic cracking units, delayed coking units, and sour water strippers. The causes of problems are discussed in relation to known limits of titanium corrosion resistance. Needs for additional data are highlighted.

Abstract Numerous approaches have been developed for mitigating stress corrosion cracking in existing BWRs. Among these, reduction of the corrosion potential provides the most efficient, consistent, and dramatic decrease in the crack growth rate of unirradiated and irradiated materials of all types. Historically, reduction in corrosion potential has been accomplished by adding H2 to the feed water to decrease the dissolved O2 and H2O2 concentrations. However, H2 concentrations greatly in excess of the stoichiometric amount are required, and factors such as the cost of H2, increased N16 in the

Abstract Hydrogen sulphide (H2S) in certain proportions in a process fluid (gas, gas condensate, crude oil, or a multi-phase system) in combination with the total system pressure, the pH of the environment, the CO2 content, and the chloride ion concentration can cause extensive damage to service equipment by inducing sulfide stress corrosion cracking (SSC), hydrogen stress cracking (HSC), hydrogen blistering, hydrogen induced cracking (HIC), and stress oriented hydrogen induced cracking (SOHIC). The propensity to hydrogen damage can be estimated on the basis of NACE MR0-175/ISO-15156 and also

Abstract Co-processing biocrude oils in existing fluid catalytic cracking (FCC) units can significantly expand the use of renewable bioenergy resources with acceptable capital expenditures. Considering the instability and high corrosivity of bio-oils, extensive studies have been done on the aging of bio-oil and corrosion of low-alloy and stainless steels under transportation and storage conditions at temperatures &amp;lt; 80 °C, which is much lower than the FCC feeding temperatures of 100–300 °C. In this work, the thermal stability and corrosivity of pinewood-derived bio-oil were evaluated by

�The lower-strength grades of steel used for transmission pipelines into the 60s were much like those used in other steel construction in that era. These steels gained strength by traditional hardening mechanisms through chemistry changes, largely involving carbon and manganese additions. Improvement of these grades, primarily through control of ingot chemistry and steel processing, became necessary when running brittle fracture was identified as a failure mechanism in gas-transmission pipelines in the late 50s. Eventually, this avenue to increasing strength was exhausted for pipeline applicat
