The traditional Rectisol process for syngas purification is characterized by high energy consumption and a need of complex *** of the crucial decisions in this process design is identification of ionic liquids(ILs)-based process to realize the syngas purification at room *** this work,a series of solvent screening procedures are carried out and finally 1-butyl-3-methylimidazolium bis(trifluor)[bmim][Tf2N]is selected as the solvent to remove CO2 and H2S from the syngas.

The computational mass transfer(CMT) aims to find the concentration profile in a process equipment,which is the most important basis for evaluating the process efficiency,as well as,the effectiveness of an existing mass transfer *** lecture is dedicated to the description of the fundamentals and the recently developed models of CMT for obtaining simultaneously the concentration,velocity and temperature *** challenge is the closure of the differential species conservation equation for the mass transfer in turbulent *** models are *** first is a two-equation model termed as c2-εc model,which is based on the Boussinesq postulate by introducing an isotropic turbulent mass transfer *** other is the Reynolds mass flux model,in which the variable covariant term in the equation is modeled and computed directly,and so it is anisotropic and *** methods are proved to be validated by comparing with experimental data.
