“…The ICrA evaluation (Tables S3 and S4) with statistically meaningful µ-values and υ-values between ranking (the lower ranking means higher intensity of foaming) with water content (µ = 0.9 and υ = 0.10) confirms that water seems to be the reason for foaming. The statistically meaningful µ-values and υ-values with viscosity (µ = 0.9 and υ = 0.10) suggest that the higher the viscosity, the higher the intensity of foaming is, which is in line with the reports of Koczo et al [67], Wang et al [68], and Pooladi-Darvish and Firoozabadi [69]. Unfortunately, the root cause for petroleum fluid foaming is still unclear [70].…”

A comprehensive investigation of a highly complex petroleum refinery (Nelson complexity index of 10.7) during the processing of 11 crude oils and an imported atmospheric residue replacing the design Urals crude oil was performed. Various laboratory oil tests were carried out to characterize both crude oils, and their fractions. The results of oil laboratory assays along with intercriteria and regression analyses were employed to find quantitative relations between crude oil mixture quality and refining unit performance. It was found that the acidity of petroleum cannot be judged by its total acid number, and acid crudes with lower than 0.5 mg KOH/g and low sulphur content required repeated caustic treatment enhancement and provoked increased corrosion rate and sodium contamination of the hydrocracking catalyst. Increased fouling in the H-Oil hydrocracker was observed during the transfer of design Urals crude oil to other petroleum crudes. The vacuum residues with higher sulphur, lower nitrogen contents, and a lower colloidal instability index provide a higher conversion rate and lower fouling rate in the H-Oil unit. The regression equations developed in this work allow quantitative assessment of the performance of crucial refining units like the H-Oil, fluid catalytic cracker, naphtha reformer, and gas oil hydrotreatment based on laboratory oil test results.

“…Previous studies identified the following factors to be responsible for foaming of alkanolamine solutions 78,79 : naturally‐occurring organic acids as constituents of inlet gases, suspended corrosion inhibiting agents, liquid hydrocarbons, surface active agents in lubricants for valves and oil for rotary equipment, injection of surplus antifoam agents, and HSSs. The most common approach to arresting foaming is the use of antifoaming agents, such as high boiling alcohols and silicone oils 80–82 …”

“…The most common approach to arresting foaming is the use of antifoaming agents, such as high boiling alcohols and silicone oils. [80][81][82] Mansooria et al investigated the foaming ability of lean MDEA solutions to determine the specific design parameters of an ion exchange resin procedure, 25 and they reported that the presence of HSS was associated with increased foaming and reduced CO 2 loading of the MDEA solutions. In their study on influence of HSSs on the absorption-desorption capacity of aqueous MEA solvent for PCC, Ling and coworkers found that foaming properties play more superior roles in the absorption rate of CO 2 in contrast to the decline of initial pH values or the declining levels of mobile amine molecules.…”

The generation of heat‐stable salts (HSSs) in alkanolamine solutions for CO2 capture processes, which is adapted for power plant technologies, exists irrespective of the class of amine solution used for the capture process. Their presence do not only trigger decrements in the CO2 absorption capacities of the solvents and contribute to further alkanolamine degradation, but also result in foaming and loss of solvents, which impacts system economics and threatens the environment. HSSs also promote the corrosiveness of the metallic structures of capture systems by lowering the pH and increasing the conductivity of the absorbent solutions. Overall, these effects substantially subvert the reliability and integrity of CO2 capture units. This survey affords sufficient background on the existence of HSSs by unraveling the flow process in a typical alkanolamine‐based CO2 capture unit with respect to their formation points and potential threats. Furthermore, the major HSSs removal and alkanolamine reclamation methodologies (electrodialysis, distillation, ion exchange, electromagnetic separation, and solvent extraction) were comprehensively explored. We believe that this review paper will benefit researchers across disciplines as we continue to explore new and complex solvent formulations to minimize the cost of CO2 capture while maximizing efficiency. © 2023 Society of Chemical Industry and John Wiley & Sons, Ltd.

“…Despite the advantages of natural gas, its production still faces hurdles, particularly in the production of gas contaminant such as hydrogen sulphide (H2S). Natural gas is considered sour when the H2S gas is approximately more than 4 ppm by volume under standard temperature and pressure [4]. It presents major problem due to its high toxicity, flammability, explosivity and corrosivity [5][6][7][8][9].…”

H2S is very well known for its toxicity, corrosivity, flammability and explosiveness which in overall lead to operational difficulty. Hence, raising the need for H2S sweetening process. However, the current conventional sweetening process is very energy intensive besides suffer from catalyst deactivation issue. Therefore, raising the need for more environmentally and economical friendly approach such as utilizing green solvent like deep eutectic solvent. Thus, the objective of this research is to determine the best combination of HBD and HBA components for catalytic DESs to convert H2S at room temperature. The study utilized COSMO-RS computational to assist in selecting the appropriate components, synthesized and characterized the chosen catalytic DES, and performed oxidative absorption of H2S using the selected DES. Initially, the solubility and selectivity performance of various HBD and HBA were evaluated, and the components with the best performance were combined with CuCl2.2H2O to form catalytic DES. The synthesized catalytic DES was characterized using FTIR and tested for its oxidation absorption capability. Based on the COSMO-RS screening, 1-butyl-3-methylimidazoilum chloride [bmim][Cl] and ethylene glycol [EG] were determined to be the best HBD and HBA, respectively. The catalytic DES formed from these components was homogeneous and brown in colour. The results of oxidative absorption showed that the catalytic DES rapidly produced a yellow precipitate, which was later confirmed to be sulphur. The study concludes that COSMO-RS computational can be used to formulate DESs for H2S oxidative absorption, and catalytic DES maintained its properties before and after H2S oxidation. The research also suggests that oxidative absorption of H2S to sulphur using catalytic DESs is a feasible and rapid.
