چکیده

A new CO2/CH4 gas separation process is presented in this paper. Capture of CO2 from natural gas is carried out using an n-alkane solvent in a conventional physical absorption process. A methodology to find optimal process condition and solvent has been developed using an advanced equation of state (SAFT-VR), process modelling-optimisation software (gPROMS), and detailed process cost estimation. Natural gas feeds containing up to 70% mol/mol of CO2 can be treated economically using this process.

Modeling and Experimental Study of Carbon Dioxide Absorption in a Flat Sheet Membrane Contactor

comIn the present study, CO2 removal from natural gas stream has been studied using a flat sheet membrane contactor. A three dimensional mathematical model is developed to describe the process. The model considers the transport of a gas mixture containing carbon dioxide and methane through a flat sheet membrane contactor module. The model is based on the non-wetted mode of operation, in which t...

Preparation of Graphene-amine Nanofluid for Absorption of Carbon Dioxide (CO2) and Hydrogen Sulfide (H2S) from a Natural Gas Stream in a Wetted Wall Column

    In this study, it was shown that how CO2 and H2S were removed from a natural gas stream, using a nanofluid containing nanoporous graphene in Diehanolamine (DEA). Before running the experiments, the appropriate values were chosen for the nanosheet dosage and the liquid and gas flow rates in the absorption experiments, which were performed in a laboratory scale wetted wall column. In the expe...
