Optimization of Energy Consumption during Natural Gas Dehydration

Abdul Qadeer, Adnan Aftab, Imran Nazir

Abstract


The aim of this work is to design an efficient Natural gas dehydration plant (using TEG as desiccant) in both terms i.e., optimized desiccants flow rate as well as optimized energy requirements. For this purpose the Natural Gas Plant of Hassan Gas Field, Shikarpur was selected as case model and the basic design study was carried out for the said plant. Natural gas is one of the important fossil fuels, used after treatment. Treatment includes removal of acid gases and dehydration. The major methods of dehydration are Direct Cooling, Absorption and Adsorption. The present work is the study of efficient design for Dehydration using absorption column by Triethylene Glycol (TEG) as desiccant. Efficiency of the Natural Gas Dehydration Column can be measured through optimized flow rates of desiccant or optimized energy requirements.
