All rights reserved.Badak LNG is a natural gas liquefaction plant, which operates LNG trains to produce LNG and refrigerated LPG. The recent annual LPG production amount is 500,000 ton/year (equivalent with 500 Million USD/year productions value). During production and storage of LPG, boil-off gas (BOG) is generated and then re-condensed in a LPG BOG Butane Condenser unit. LPG BOG Reliquefaction system uses centrifugal compression system with total maximum electric power duty of 1.4 MW (equivalent with 2.4 Million USD/year operating cost). Cooling medium flow rate in condenser unit is controlled by using Butane Tank pressure controller or cooling medium temperature outlet controller. Normally, the pressure controller dictated the cooling medium flow rate. However, during accumulations of Non-Condensable Gas (NCG) occurrence in the condenser unit hot stream side (LPG BOG Butane) will lead to cooling medium temperature outlet controller dictation which indicates less LPG BOG Butane condensing rate. Furthermore, this less condensing rate will lead to LPG Butane tank overpressure flaring (LPG Butane product losses) accounted as LPG Butane storage efficiency for just 91.42%.[/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][/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=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
