PT Donggi-Senoro LNG (DSLNG) proudly explained the innovations first implemented in the LNG refinery in Indonesia during the Technical Program presentation at The IPA Convex 2024 event, held from May 14-16, 2024, at ICE BSD City, Tangerang. DSLNG's presentation was delivered by Process Engineer Indah Fajarina Dewi on the second day of The IPA Convex 2024, Wednesday (15/05/2024). This effort is part of DSLNG's commitment to improving energy efficiency and reducing emissions at the LNG plant by introducing an innovative defrosting method. The presentation focused on applying Boil-Off Gas (BOG) as defrost gas, which was used at an LNG plant in Indonesia for the first time. Utilizing BOG as defrost gas saves energy and reduces environmental impact. Energy savings are measured by the amount of feed gas used as defrost gas during Liner and Transition Piece Inspection (LTPI) and Major Inspection (MI), amounting to 44.2 MMSCF (million cubic feet per day), equivalent to a reduction in emissions of 2,209 tons of CO2.
