SIMULATION OF NATURAL GAS SWEETING PROCESS USING MONOETHANOLAMINE (MEA)

الملخص

The process of remove acid component for natural gas is called gas sweeting, this is attained by absorbing them with basic solution such as alkanolamines, through a reversible exothermic reaction that subsequently allow for their regeneration. In this theoretical investigation, the absorption of CO₂ and H₂S present in natural gas using the ASPEN HYSYS V.14 process simulator with chemical solvent package for amines, using an aqueous monoethanolamine solution (MEA) as an absorber. The ASPEN HYSYS is a good tool for calculating process operating variables. Thus, fitting results were obtained absorption when the flow rate and concentration of amine are increased. The process absorption proceeds best at low temperature and high pressure; conversely, the desorption process improves at high temperatures and low pressure.
