Natural gas is one of the major sources of fuel and raw material to industries all over the world. However, it contains some acid gases such as CO2 and H2S which are corrosive and harmful to the environment. These acid gases must be brought to permissible limits to promote safety in the operation and increase the heating value of the natural gas. In this project, we design an acid gas removal plant based on the amine treatment process using ASPEN HYSYS software.
In our proposed design, a counter-current flow occurs between the rising sour gas and the descending methyldiethanolamine (MDEA), thereby, absorbing the acid gases. MDEA is recycled back to the absorber column, while the acid gases are separated into their respective components of CO2and H₂S respectively. CO2can be used for enhanced oil recovery while H₂S can be used in petrochemical processes such as production of rubber, sulfuric acids and medicines.
The use of activated MDEA for the acid gases absorption, which encapsulates a combination of two different amines, say MDEA and DEA, is recommended for future developments of this project. The total utilities and installed cost for our proposed natural gas sweetening plants are $1,315,710 and $1,671,800 respectively.
