Based on the validated model calculation, the optimization of the system was carried out through the selection of variations of the gas removal system (GRS) of the non-condensable gasses (NCGs). Five GRS schemes were carried out in this study: a one-stage steam ejector, a two-stages steam ejector, a one-stage liquid ring vacuum pump (LRVP), a two-stage LRVP, and a hybrid system (ejector plus LRVP). The proposed scheme shows that one-stage LRVP system achieved the best model for the GRS in the proposed plant, generated an electric power of 15.94 MW, representing a 7.6% increase to the current 200 MW installed capacity, with a house load energy consumption of 755.18 kW.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]The authors would like to express their deep thanks to Indonesia Power Ltd. for the assistance in providing some data required in this study.
