“…As reported in our previous paper [3] the accuracy and reliability of the experimental data produced by the apparatus developed in this work was checked through comparison of the measured solubility, density and viscosity of pure sulfolane, pure methanol and the (CO 2 -methanol) binary mixture with the available experimental data reported in the literature [4,33]. The Sih et al [4] and Chiehming et al [33] methods are in principle similar to the method used in this work.…”

“…However, data regarding acid gas adsorbed in physical and chemical solvents are scarce. Jalili, et al [3], have reported density and viscosity of sulfolane loaded by CO 2 and H 2 S and sih et al [4] have reported those properties of CO 2 -methanol system. Both reported data [3,4] have shown that density and viscosity of sulfolane and methanol loaded with CO 2 reduce with increasing loading.…”

As a result of the increased energy demand and the required environmental compliance, purification of natural gas (NG) need to be processed through more efficient technologies. Most the NG sources contain H2S and CO2 as acidic contaminants causing corrosion, reduction in the calorific value of the fuel, and toxicity. Removal of these gases (gas sweetening) is mostly performed in a reactive absorber followed by a stripper for solvents regeneration. Amine solvents are very suitable due to their natural affinity towards the acid gases. In the setting‐up of newer plants or retrofitting of old units in existing plants to improve the efficiency of the sweetening process, modeling, optimization, and safer operational control of the process have drawn the attention of many researchers. The development of better models must take into account the synthesis and implementation of proper control strategies. Rate‐based, equilibrium, and kinetic models supported by thermodynamic properties of the components have been discussed here and experiments carried out to identify new process models have also been presented.

Summary The emission of greenhouse gases from fossil‐fueled power plants is a major concern in power generation sector. Carbon dioxide (CO2) emissions constitute the major portion of the greenhouse gases. Among several opportunities available to reduce CO2, carbon capture and sequestration (CCS) is considered to be a possible option for CO2 mitigation. However, implementation of CCS increases the cost of power generation significantly. The main effort of this study is to explore the technical and economic aspects of a dual‐stage Selexol process and a proposed process named combined Sulfinol‐Selexol process, for pre‐combustion capture. The combined CO2 capture process utilizes Sulfinol‐M solvent‐based process for the selective capture of hydrogen sulfide and dimethyl ether of polyethylene glycol solvent‐based Selexol process for CO2 capture. The performance of both processes is assessed and compared in terms of energy consumptions, operating cost, and capital cost by simulating in Aspen HYSYS V.11. Sensitivity analysis for lean solvent inlet temperature, pressures of multi‐flash system and number of stages of the absorption columns is performed to improve both processes. The proposed combined process is 5.8% more economical than the baseline dual‐stage Selexol process as well as its overall process is simpler. However, after sensitivity analysis, both processes improved, and the dual‐stage Selexol process is found to be 3.31% more economical than the combined Sulfinol‐Selexol process.
