the object of this work is solubility correlation and prediction of co2 and h2s in various aqueous alkanolamines using the electrolyte cubic square-well equation of state (ecsw eos) [haghtalab, a.,mazloumi, s. h., (2009a), fluid phase equilib.,285,96-104]. the eeos systematically is applied to describe the solubility of acid gases in various alkanolamine solutions, including mdea, mea, dea, amp...

in this work, the pc-saft equation of state (eos) has been used to model the solubility of acid gases (co2 and h2s) in two imidazolium-based ionic liquids (ils) ([c8-mim][pf6] and [c8-mim][tf2n]). parameters of pure ils were estimated using experimental densities. two strategies were considered to model densities of pure ils. in strategy 1, ils were modeled as nonassociating compounds and in st...

the density and viscosity of carbonated aqueous 35wt% methyldiethanolamine solution were experimentally measured accompanied with the solubility of co2 at temperatures from (303.15 to 363.15) k and pressures up to 0.8 mpa using the new setup developed in our laboratory.it was observed that both density and viscosity of mixtures decrease by increasing temperature and increase by increasing acid ...

Hydrocarbons are sparingly soluble in aqueous solvents and to a first approximation their solubility can be described by the traditional Henry’s Law, which linearly relates the mole fraction in water to gas-phase partial pressure. The presence of amines in the aqueous phase increases hydrocarbon solubility over that in water, an effect referred to as “salting-in”. Commercial amine treating solu...

in natural gas treatment, the removal of co2 and h2s in acid gases is a critical concern. there are various purification technologies that can be used for the removal of acid gas impurities. absorption of acid gas into amines is one preferred method in gas industries. in the past, single amines was used, but recently in order to improve absorption performance, mixed amines with different solubi...
