Total production capacity is 22.5 MTPA of LNG and 1.02 MTPA of LPG. PTB recieves gas from gas producers contain small amount of liquid hydrocarbon. The liquid hydrocarbon is separated in Knock Our Drum (KOD) then to be stabilized in the condensate stabilizer unit that consist of two distillation column operates in Low (LP) and High Pressure (HP). Such liquid hydrocarbons namely Badak Return Condensate (BRC) is sent back to gas producer Since there are changes in feed gas both quantity and quality, therefore the HP column performance is reduced. The column has been operated at 70% of its design capacity and achievement of targeted Reid Vapor Pressure (RVP) is only 64.6%. Thermal analysis indicated that about 4 Gcal/hr is not used effectively in the condensate stabilizer unit. To solve the problem, it is conducted a study using column thermal analysis. The thermal analysis has been conducted based on some developed case studies. From those alternatives, it is concluded that the optimum operating condition of HP column can be achieved by relocating the liquid feed from tray#1 to tray#2, vapour feed relocation and followed by operating mode adjustment. The operating mode adjustment is conducted by re-setting the flow and temperature of the feed. The proposed modification and operating mode adjustment can improve the effectivity of enegy utilization in HP column as much as 4 Gcal/hr while the RVP can be maintained at 8 Psia. © (2014) Trans Tech Publications, Switzerland.[/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]Condensate,Liquefied Natural Gas (LNG),Liquid hydrocarbons,Optimum operating conditions,PNMTC,Production capacity,Reid vapor pressure,RVP[/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]Column,Condensate,Distillation,LNG,PNMTC,RVP,Thermal analysis[/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]https://doi.org/10.4028/www.scientific.net/AMM.493.27[/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]
