【 摘 要 】

It has always been an aspiration for a Liquefied Natural Gas (LNG) plant to be able to monetize natural gas to its design plant capacity and best plant efficiency. Being able to achieve design capacity means project investment is paid off, whereas operating at the best efficiency means operating cost is optimum. Malaysia LNG Sdn Bhd (MLNG SATU) is consistently operated at design nameplate capacity post MLNG Rejuvenation and Revamp (MRR) project in 2005. Existing process control and optimization program has been helping the plant to consistently achieve maximum plant capacity within constraints on operational target and equipment performance. MLNG Molecule Allocation Program (M-MAP) was developed in 2016 to improve current program by looking at the plant thermal efficiency aspect, defines as Process Efficiency (PE). Leveraging on good existing plant data acquisition system and effective process control and optimization program in MLNG SATU, M-MAP has successfully expanded from a simple engineering calculation to a program that enables MLNG SATU production to achieve at its best efficiency. Developed in bi-phases, the Phase 1 of M-MAP has improved the overall efficiency of MLNG SATU by 1.3%. The Phase 2 of the M-MAP is currently under implementation; expecting another step in the overall efficiency of MLNG SATU within 0.5%.
