Abstract
Contaminated natural gas when carelessly handled, often poses human and equipment related problemsranging from lung and skin infections to corrosion, equipment fouling/failure and reduction in gas qualityowing to the presence of acid gases. In this work, four natural gas (NG) samples were treated to removeCO2and H2S using 10–50% Di-Ethanolamine (DEA) solutions mixed with 5% w/w 0.1 M calcium hydrox-ide. The treatment process gave increased acid gas removal at increased DEA concentrations. Based on thesimulation results, cost effective treatment of the gas samples, require 0.1 M Ca(OH)2and DEA mixedsolutions in the range of 27.4–30%. The optimum mixture concentration for the gas treatment was foundto be 30% Ca(OH)2-DEA hybrid solution with feed gas flow rate of 830 kscf/h. In terms of pressure energyconsumption, pumping the hybrid mix at 830 kscf/h will save pressure energy as compared to pumpingthe feed gas at 1024.58 kscf/h since the lower and upper limit feed gas flow rates gave similar results.
