Effect of Liquid Flow Rate and Amine Concentration on CO₂ Removal from Natural Gas at High Pressure Operation in Packed Absorption Column

Abstract:

Greenhouse gas (GHG) emissions such as carbon dioxide (CO₂) and methane (CH₄) from oil and natural gas operation at offshore platforms have significant contribution to global warming. The reduction of these GHG emissions is possible through CO₂ capture technology. This study reports the absorption performance of monoethanolamine (MEA) for the removal of CO₂ from natural gas (NG) at high pressure conditions. The absorption experiments were performed in an absorption column packed with Sulzer Metal Gauze Packing at 5.0 MPa operating pressure. The absorption performance was evaluated in terms of CO₂ removal (%) with liquid flow rate ranging from 1.81 to 4.51 m³/m².h and MEA concentration of 1.0 - 4.0 kmol/m³. It was found that CO₂ removal (%) had increased with increasing liquid flow rate and MEA concentration.
