Implementation of physical solvents at low temperature for natural gas processing
Due to lack of information at low temperature, the development of new and more economical processes for natural gas processing in the presence of physical solvents requires additional knowledge of thermodynamic properties such as density, viscosity, solubility and distribution coefficients in phase equilibrium. In the new integrated process developed by IFP, the objective is to achieve simultaneously dehydration, sweetening and extraction of natural gas liquids by contacting the gas with a physical solvent at low temperature. Recommended solvents should have the following characteristic properties: inhibition of hydrate formation, high solubility for acid gases and immiscibility with hydrocarbons. The performances of some heavy solvents such as dimethylformamide (DMF), N-methylpyrrolidone (NMP) and N-formylmorpholine (NFM) by comparison with other light solvents are investigated.
