Global demand for LPG has grown at about 2.9%/year in the past 10 years, or roughly two times faster than demand for petroleum. Total global LPG demand in 2003 was 207 million tones. Demand for LPG in Japan has been slightly smaller to 18.05 million tones. LPG production from NGL in natural gas field and oil field accounted for about 60% of the total supplies and refineries typically produced about 40% consistently. As LNG trade is expanding, removing the LPG from the LNG stream is going to be important source. Beside gas producing countries as Saudi Arabia have expanded demand rapidly for LPG as petroleum chemical feedstock. According to the statistics of USGS (United States Geological Survey) and the United Nations, the world resources of LPG are estimated 22.1 billion tones and the reserves of LPG are estimated 5.9 billion tones. The resources of LPG are 11% of oil and same percentages of natural gas. The reserves of LPG are 7.7% of oil and 8.5% of natural gas. It is very difficult that DME would be a substitute fuel of LPG as domestic use in Japan because it has lower calorific value. LPG synthesis research from natural gas is progressing in Japan. The research would be completed at least 4 years. The world LPG supply would be tight till 2010 as rapid growing demand and slower supply capability growth.
