Abstract

Natural gas is one of the major energy sources in the world. Its' major usage includes power generation, as transportation fuel and as raw material to produce ammonia and other petrochemical products. BP Global (2011) stated that the world consumption of natural gas for the past year has increased 7.4%. This is the highest increase since 1984. Among the major importers of natural gas are UK, Japan and South Korea. Both Japan and South Korea, who are the world's largest and second largest LNG importers respectively, receive their supply from Malaysia. As of January 2011, Malaysia has 83 Trillion Standard Cubic Feet (TSCF) of natural gas in proven reserves, (Oil & Gas Journal, 2011). This places Malaysia in the fourth place as the country in Asia Pacific with the most natural gas in reservoir. The exploration and production activities in Malaysia are intensive and it is estimated in 2010 that the gross natural gas production is 2.7 TSCF. A typical composition of natural gas before it is refined contains hydrocarbon, nitrogen, carbon dioxide and hydrogen sulphide. Natural gas production often produces water as well. This water must be removed as it can pose many problems such as the formation of hydrates. Hydrates are solids formed by methane, carbon dioxide and water. It can clog the pipelines, thus decreasing the flow efficiency. Furthermore, water can also combine with hydrogen sulphide and carbon dioxide to form acid. This acid corrodes the pipelines transporting gas to onshore. As a result, high cost is incurred as a special anti-corrosive material is needed to coat the pipeline. To avoid these problems, water must be removed from natural gas.
