Performance optimization of an industrial natural gas dehydration process to reduce energy consumption and greenhouse gases (GHGs) emission

Abstract

Natural gas dehydration using multi-layer adsorption beds is one of the most essential processes in gas processing plants, where the water molecule is removed from raw gas by a continuous cyclic temperature swing adsorption operation. In the present research, a commercial adsorption unit for dehydration of natural gas has been studied, and the effects of the volume of adsorbents in the multi-layer adsorption beds on the overall performance of the process have been investigated using a precise mathematical model. The numerical method of lines (NMOL) has been applied to solve the partial differential equations (PDEs) demonstrating the fixed bed. The real plant data from the industrial unit hav..
