Moreover, economic analysis reveals that SGM has 38% lower annual operating cost compared to CDM. The analysis shows that SGM gives 46% lower TEG feed rate, 42% lower reboiler duty and 99.97% pure regenerated TEG. The optimized processes are set to achieve a targeted value of water content in dry gas and analyzed at optimized point. ![]() ![]() To optimize the CDM and SGM, the sensitivities of the water content of dry gas, reboiler duty and raw material loss are analyzed against solvent rate and stripping gas rate. 摘要: In the present work, the conventional natural gas dehydration method (CDM) and stripping gas method (SGM) are technically and economically analyzed, utilizing Aspen HYSYS and Aspen Process Economic Analyzer (APEA), respectively. ![]() Key words: Natural gas dehydration, Technical analysis, Parametric optimization, Economic study, Aspen HYSYS
