Abstract:
Perovskite LaFeO3/ZSM-5 is synthesized via citrate route for H2S removal at high temperatures. It shows good thermal stability after heat treatment at 500–700∘C with respect to slight changes in crystallographic phase and textural property. It presents the optimal desulfurization performance at 600∘C with sulfur capacity of 1017[Formula: see text][Formula: see text]mol[Formula: see text]S/g and products of S, LaS2, and Fe7S8. Sulfidation at 500∘C yields the same products as sulfidation at 600∘C but displays the lowest sulfur capacity of 408[Formula: see text][Formula: see text]mol[Formula: see text]S/g. Sulfidation at 700∘C produces La2O2S, Fe3S4, and unreacted LaFeO3. The activation energy of the sulfidation reaction over LaFeO3/ZSM-5 is 109.6[Formula: see text]kJ/mol.

Abstract:
Many modern sulfur recovery unit process waste heat recovery exchangers operate in high-temperature environments. These exchangers are associated with the thermal reactor system where the tube-sheet–tube-ferrule assemblies are exposed to gasses at temperatures approaching 3000°F. Because sulfur compounds are present in the process gas, the carbon steel tube sheet and tubes in the assembly will be deteriorated by sulfidation as the operating metal temperature rises above 600°F. Ferrule systems are used to protect the carbon steel from exposure to excessive temperatures. The temperature distribution in the steel tube-sheet–tube-ferrule system is affected by process gas flow and heat transfer through the assembly. Rather than depend on “assumed” heat transfer coefficients and fluid flow distribution, a computational fluid dynamics investigation was conducted to study the flow fields and heat transfer in the tube-sheet assembly. It was found that the configuration of the ferrule installation has a large influence on the temperature distribution in the steel materials and, therefore, the possible sulfidation of the carbon steel parts.

Abstract:
Aluminium smelting is a high temperature electrometallurgical process, which suffers considerable inefficiencies in power utilization and equipment maintenance. Aluminium smelting cell works in the extreme environments that contain extraordinarily aggressive gases, such as HF, CO and SO2. Mild steel used as a structural material in the aluminium industry, can be catastrophically corroded or oxidized in these conditions. This project was mainly concerned with extending the lifetime of metal structures installed immediately above the aluminium smelting cells. An aluminium-rich coating was developed on low carbon steel A06 using pack cementation technique. Yttria (Y2O3) was also used to improve the corrosion resistance of coating. Kinetics of the coating formation were studied. XRD, FESEM and FIB were employed to investigate the phase constitution and the surface morphology. Together with other potentially competitive materials, aluminium-rich coating was evaluated in simulated plant environments. Results from the long time (up to 2500h) isothermal oxidation of materials at high temperature (800??C) in air showed that the oxidation resistance of coated A06 is close to that of stainless steel 304 and even better than SS304 in cyclic oxidation tests. Coated A06 was also found to have the best sulfidation resistance among the materials tested in the gas mixture contains SO2 at 800??C. Related kinetics and mechanisms were also studied. The superior corrosion resistance of the coated A06 is attributed to the slow growing alpha-Al2O3 formed. Low temperature corrosion tests were undertaken in the gas mixtures containing air, H2O, HCl and SO2 at 400??C. Together with SS304 and 253MA, coated A06 showed excellent corrosion resistance in all the conditions. The ranking of the top three materials for corrosion resistance is: 253MA, coated A06 and SS304. It is believed that aluminised A06 is an ideal and economical replacement material in the severe corrosive aluminium smelting cell environment.

Abstract:
Industrial and power generation processes employ units like boilers and gasifiers to burn sulfur containing fuels to produce steam and syn gas (H2 and CO), which can generate electricity using turbines and fuel cells. These units often operate under environments containing gases such as H2S, SO2, O2 etc, which can attack the metallic structure and impose serious problems of corrosion. Corrosion control in high temperature sulfur bearing environments is a challenging problem requiring information on local gaseous species at the surface of alloy and mechanisms of degradation in these environments. Coatings have proved to be a better alternative for improving corrosion resistance without compromising the bulk mechanical properties. Changes in process conditions may result in thermal and/or environment cycling between oxidizing and sulfidizing environments at the alloy surface, which can damage the protective scale formed on the alloy surface, leading to increase in corrosion rates. Objective of this study was to understand the effect of fluctuating environments on corrosion kinetics of carbon steels and develop diffusion based coatings to mitigate the high temperatures corrosion under these conditions. More specifically, the focus was : (1) to characterize the local gaseous environments at the surface of alloys in boilers; (2) optimizing diffusion coatings parameters for carbon steel; (3)understand the underlying failure mechanisms in cyclic environments; (4) to improve aluminide coating behavior by co-deposition of reactive elements such as Yttrium and Hafnium; (5) to formulate a plausible mechanism of coating growth and effects of alloying elements on corrosion; and (6) to understand the spallation behavior of scale by measuring stresses in the scales. The understanding of coating mechanism and effects of fluctuating gaseous environments provides information for designing materials with more reliable performance. The study also investigates the mechanism behind the effect of REs on scale adhesion and sulfidation behavior. Thus, the present work will have a broad impact on the field of materials and coatings selection for high temperature industrial environments such as boilers and gasifiers, and provides information on RE-modified aluminized coatings on carbon steel as an alternative for the use of bulk superalloys under high temperature sulfur bearing environments.

Abstract The purpose of the thesis is to study the high-temperature sulfidation and thermal-cycling corrosion behavior of In-738 superalloy over the temperature range of 500~900℃ in a pure sulfur pool with the sulfur-vapor range of 10-3~10-1 atm and in H2/H2S mixed gases having partial pressures of sulfur in the range of 10-9~10-3 atm. The sulfidation kinetics followed the parabolic rate law, and the corrosion rates increased with increasing temperature. The scales formed on the alloy were duplex and temperature-dependent, consisting of the outer and the inner layers. The outer scales formed at 500~600℃ consisted of mostly nickel sulfide (NiS) and minor cobalt sulfides (CoS2), while the inner layer was a heterophasic mixture of NiS, CoNi2S4, and minor amounts of Al2S3 and Cr2S3/Cr3S4. The outer scales formed at 700~900℃ consisted of mostly nickel sulfide (Ni3S2) and minor amounts of Co3S4 and Cr2S3/Cr3S4, while the inner layer was a heterophasic mixture of Ni3S2, Al2S3, and CoCr2S4. The scales formed in the H2/H2S mixed gases are similar to those presented in the pure sulfur-vapor except the CoMo2S4 was also detected in the inner layer. The sulfidation rates in the mixed gases are much higher than those in the pure sulfur-vapor. Platinum markers were found to be located at the interface between the inner and outer scales, suggesting that the outer scale grew by outward transport of cations (Ni, Cr, and Co) and the inner scale grew by the inward transport of sulfur. The thermal-cycling corrosion rates of In-738 superalloy over the cycling temperature between 100 and 850℃ at Ps2=10-1 atm decreased with increasing cycling times. The nodule-shaped Ni3S2 is the main scale observed after several cycling-times.

High-temperature sulfidation behavior of three special-purpose stainless steels (containing 13-8 precipitation-hardenable martensitic stainless steel (13-8PH), 2205 duplex stainless steel (2205DSS), and UNS31254 super stainless steel (31254SS)) over the temperature range 500~900℃ in H2/H2S and H2/H2S/H2O. The corrosion kinetics followed the parabolic rate law in all cases. The corrosion rates increased with increasing temperature and presence of water vapor. In general, 13-8PH is the most sulfidation resistant alloy in the current study. The scales formed in H2/H2S mixed gases on the steels were complex and heterophasic, consisting of the outer layer of mostly iron sulfide (Fe1-XS or FeS) and iron-nickel sulfide ((Fe,Ni)9S8), while the inner layer was a heterophasic mixture of Fe1-XS, FeCr2S4, CrMo2S4, and minor Al2S3 (for 13-8PH), or minor Cr2S3 and Mo2S3 for (2205DSS). The outer layer of mostly (Fe,Ni)9S8 was detected for 31254SS, while the inner layer was a heterophasic mixture of Fe1-XS/FeS, FeCr2S4, FeMo2S4/ FeMo4S6, and Cr3S4. The scales formed on all the steels in the H2/H2S/H2O gas mixture were similar to those of in the H2/H2S gas mixture, and no evidence of any oxides was found.

This study is based the observation of corrosion on a circulation loop system at the coal tar distillation plant over a period of several years. Leakage of the pipeline and major facility was damaged as well. Seventeen emergency shut off had been occurred for this reason from 1997 to 2002. Fire alerts were also occurred due to autoignition of FeS, product in the corrosion reaction, which has drew the attention of the safety concerns. Corrosions of the equipment, frequencies of emergency shut down, and the cost of the inspection is relatively higher than the expected. This potential industrial hazardous of the distillation plant was not well studied in the past. Changing the corroded pipeline and adding corrosion inhibitor might be beneficial of preventing corrosion of the system. However, the improvements of using these methods are limited. Based on the literature search regarding the corrosion mechanism, corrosion in this case was believed to be triggered under the presence of trace amount of sulfide in the fluid at a high operation temperature. Either H2S or naphthenic acid is not able to initiate the reaction as we originally expected. It was generally believed that there will be no corrosion reactions over the equipment if the sulfide content in the mixture stream is lower than 0.6%. Nevertheless, it is not true upon completion of this study. Corrosion protection strategies have been studied by knowing the various reasons triggering the corrosion reaction over the equipment. Changing the equipment pipeline will be the best remedy under the economical and safety concerns. Suggestions of using different plumbing materials under different operation condition were made in this study, which may reduce the potential industrial hazard under the operation condition. The suggestions may also be beneficial of enhancing the public safety concerns.

High-temperature sulfidation of AISI 310 stainless steel coated with Mo-Al film (containing pure Mo, Mo-20 or -32 at.% Al) was studied over the temperature range of 700-900℃ in a pure sulfur pool with the sulfur pressure range of 10-3-1 atm. The Mo-Al coating was prepared by the R. F. magnetron sputtering deposition at 200℃, and the thickness of each coating was controlled at bout 2 μm. The corrosion kinetics of all coating alloys followd the parabolic rate law in all cases, and the sulfidation rate constants increased with increasing temperature but decreased with increasing Alcontent in the coating composition. The scales formed on all alloys were duplex, consistting of an outer layer of mostly iron sulfide (FeS or Fe1-xS), chromium sulfide (Cr2S3/Cr3S4), molybdenum sulfide (MoS2) and an inner complex scale of FeS/Fe1-xS, Cr2S3/Cr3S4 and minor Al2S3, Fe1.25Mo6S7.7, Al0.55Mo2S4.

Full text
Abstract:
Sulfidation corrosion of the carbon steel tubes at the tube-to-tubesheet joint often governs the life of waste heat boilers in sulphur recovery plants. Conventional tube joints typically have a welded joint located at the hot-side face of the tubesheet. An alternative design involves welding the tubesheet joint at the cold-side face of the tubesheet, close to the boiler feed water. The alternative design also employs stainless steel cladding on the tubesheet face and a tube-hole sleeve selectively at high-temperature locations. Finite element heat transfer analysis is used to establish the thermal profiles of the conventional and the alternative designs. From the worked example, the alternative design provided a lower metal temperature by approximately 80 °F at the joint, as compared to the conventional tube joint. Sulfidation rate prediction based on a sample gas composition using ASSET (Alloy Selection System for Elevated Temperatures) Software predicts that the alternative design can reduce the sulfidation rate by 35% because of the lower metal temperature.

Abstract:
Abstract High temperature corrosion is a serious problem on tlie heat exchanger tubes of recuperators because they encounter an corrosive environment at maximum temperature around 900°C. These tubes were found to be corroded via oxidation, sulfidation and molten salt corrosion. Particularly molten salt corrosion could be the most severe corrosion mechanism. As a protective coating for recuperators, nickel and cobalt based self-fluxing alloys, iron based amorphous alloy and chromium carbide cermet coatings were considered. These coatings were prepared by an arc spray and or/not fusing or a HVOF spray. Their molten salt corrosion resistance was tested, and the high temperature corrosion resistance in a SO2 containing atmosphere was examined. Also microstructures of the coatings were studied after corrosion tests.

Abstract:
Many modern industrial processes require high-temperature alloys with superior environmental resistance and high-temperature mechanical properties. This paper describes a recently developed Fe-Ni-Cr-Nb-N alloy (HAYNES® HR-120® alloy) which is being used in several modern high-temperature industries. This alloy utilizes niobium (columbium) nitride and carbide strengthening mechanisms for its excellent tensile and creep-rupture strength characteristics. These properties are significantly higher than those of regular Fe-Ni-Cr alloys and some Ni-base alloys. The alloy also exhibits excellent resistance to oxidation and sulfidation needed for applications in many of these industrial processes. This alloy is increasingly being used in the petroleum refinery, waste incineration, oil and gas recovery, heat treating and land base gas turbine industries. Major properties, alloy characterization and industrial applications for this alloy are reviewed in this paper.

Abstract:
It is known that the efficiency of a gas turbine engine can be improved substantially by increasing the operating temperature. However, increasing the temperature puts a tremendous demand on the performance of materials of construction such as the combustion chamber, transition ducts etc. The material has to be resistant to long-term isothermal and cyclic oxidation conditions. In addition, the thermal stability of the alloy is of utmost importance. INCONEL® alloy 617 is a solid solution, nickel - chromium - cobalt - molybdenum alloy with an exceptional combination of high-temperature strength and oxidation and carburization resistance. In this paper, the performance of alloy 617 in isothermal and cyclic oxidation, carburization and burner rig oxidation/sulfidation environments will be presented. In addition some mechanical properties data will be included to show the stability of the alloy after exposure to high temperatures for extended periods of time. For comparison the data obtained on such alloys as INCO® alloy HX and Haynes® alloys 188 and 230 will also be reported.

Abstract:
There has been a need for suitable coatings to provide protection for a sufficient length of time to match the outstanding high temperature strength capabilities of Mechanically Alloyed (MA) ODS superalloys. The quest for such coatings has instigated many research studies. The findings reported here evolved from studies on substrate composition effects and coating application types and structures that are necessary in order to develop viable substrate-coating systems. The systems were evaluated using cyclic and isothermal oxidation tests and Burner Rig hot corrosion (sulfidation) tests. The results indicate, inter alia, beneficial substrate compositional effects from Al in high Al/γ′ phase superalloys. Compatible overlay coatings of, for example, NiCoCrAlY(Ta) for INCONEL* alloy MA 6000 and advanced industrial ODS superalloys, such as INCONEL alloy MA 760, were identified that are commercially available. These conclusions are supported by initial results from a much broader coatability program currently in progress. This program also includes several combinations of duplex coatings, utilizing a compatible inter-layer coating, that have enhanced both coatability and corrosion resistance performance of these Ni-based ODS superalloys.

Abstract:
M-Cr-Al-Y and in particular Fe-Cr-Al-Y alloys with high aluminium matrix content have a tendency to form thin, stable and tightly adherent alumina scales even at low oxygen partial pressures. This forms the basis of their superior hot gas oxidation, carburization and sulfidation resistance when used at high temperatures. However, the same tendency makes the alloys more difficult to braze because the easily formed and highly stable ceramic surface layers significantly reduce wettability and hence braze flow. Fe-Cr-Al-Y alloys have recently been suggested as promising alloys for use in gas turbine engines as abradable honeycomb gas path seals. This paper reviews the vacuum brazing of honeycombs made from highly alloyed Fe-Cr-Al-Y foils to metal backing members. Most suitable Fe-Cr-Al-Y materials, commercial braze filler alloys and braze cycles are presented. Emphasis is placed on industrial equipment rather than laboratory vacuum furnaces. Brazing under high vacuum conditions in all-metal furnaces is recommended as a brazing procedure for honeycomb made from MI 2100, which is high in aluminium content, to various commonly used carrier structure alloys.
