Liquefied Natural Gas (LNG) terminal is one of new construction in Map-Ta-Pud (MTP) during 2007-2011. With the process of regasification, LNG will be heated by seawater and change phase from liquid to vapor. The energy for phase changing was lost by seawater to sea. Therefore the objective of this study is to design the integrated process for all plants in MTP to reducing the emission with the utilization of lost energy in LNG regasification process. The simulation result shows that this integrated process with LNG energy utilization can reduce the toxic and emission in MTP atmospheric. The total toxic recovery = 99.2-99.4 %. The BTEX recovery and VOC recovery = 100 % and sulfur compound recovery = 95-97%. In addition, the preliminary of economic evaluation and sensitivity analysis show that the payback period of this gas treatment process can be possible in 2-8 years.
