The purpose of the present study was to propose a new simulation model for calculation of the viscosity of the mono-ethanol amine-ionic liquid (MEA-IL) solvent in the CO 2 -capturing pilot plant. To do so, a combination of the pseudo-ideal solution model (PISM) and Eyring's mixture viscosity equation was implemented in MATLAB. Moreover, the various thermodynamic models were used to calculate viscosity, using solvent containing MEA-IL in the high CO 2 feed gas. The present study determined the viscosities of the MEA-IL blends at different concentrations and various temperatures in the CO 2 capturing pilot plant. The results were comparable to those obtained from the Eyring-PISM model, Eyring-Wilson method, Cheng and Meisen a previous study equation, and the Aspen Plus and Promax with electrolyte non-random two-liquid model that presented the actual viscosity values of the liquid solutions. The calculated solvent viscosity values with the Eyring-PISM model at different temperature profiles were achieved using an average absolute deviation (AAD) of about 1.164% and 1.422% in absorber and desorber for solvent (MEA = 27 wt% and IL = 34.2 wt%) and 1.578% and 1.868% in absorber and desorber for solvent (MEA = 29 wt% and IL = 37.12 wt%), respectively. The consideration of a suitable model for the determination of viscosity has a significant role in energy consumption in the CO 2 -capturing pilot plant. The estimated energy consumption with the Eyring-PISM model was achieved using an AAD of about 0.652% for solvent (MEA = 27 wt% and IL = 34.2 wt%) and 0.502% for solvent (MEA = 29 wt% and IL = 37.12 wt%), respectively. The results obtained from the Eyring-PISM simulation model using the experimental data revealed a high degree of accuracy.

Sulfur-containing polymers and poly(ionic liquid)s are emerging macromolecules with unique properties and applications. This article shows the first integration of these two polymer families, leading to materials with a unique combination of properties. The synthetic strategy toward sulfur-containing poly(ionic liquid)s involves first the copolymerization of elemental sulfur with 4-vinylbenzyl chloride and subsequent quaternization of the alkyl chloride group using N-methyl imidazole. The synthetic pathway is completed by the anion exchange reaction of the poly(sulfur-co-4-vinylbenzyl imidazolium chloride) by a sulphonamide anion. The obtained polymers are fully characterized by NMR, FTIR, SEC, DSC, and TGA. The sulfur poly(ionic liquid)s combine some properties related to its poly(ionic liquid) nature, such as anion-dependent solubility (water vs organic solvents) and high ionic conductivity as well as properties related to its sulfur content, such as redox activity.
