T2.10 MLNG Molecule Allocatıon Program (M-MAP)

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 at 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 to its best efficiency.

Developed in bi-phases, the Phase 1 of M-MAP looks into maximizing overall process efficiency of MLNG SATU modules while the Phase 2 focuses on closing the efficiency gaps between the modules. Phase 1 or also known as M-MAP Automation determines the best combination of production target among LNG modules that leads to higher process efficiency. Post implementation in 2017 observed an increase of process efficiency in MLNG SATU by 1.3%. Phase 2 named as PE Gap Analysis Tool has identified efficiency gaps among the modules which has led to multiple resolution initiatives created for MLNG SATU in 2017; approached either operationally, via control improvement or as part of maintenance activity. Upon implementation of the initiatives, the process efficiency of MLNG SATU in 2018 has increased by more than 0.5%. The success implementation in MLNG SATU has opened up the opportunity for similar application to be embedded in other LNG Plants for maximum realization of benefit to Petronas LNG Complex (PLC) as a whole.
