1323Liquefied Petroleum Gas LPG

Nationwide, approximately 45% of LPG comes from petroleum refining, with the balance from natural gas processing. Most residential gas appliances operate on LPG, i.e., barbecue grills, portable space heaters, and home heater units in rural areas that lack natural gas pipelines. Therefore, unlike CNG or LNG, LPG enjoys an extensive, mature distribution network nationwide. LPG is normally stored on-site under relatively low pressures. The bulk of LPG produced in North America is commonly used in central heating systems and as a feedstock in chemical plants. LPG is now aggressively marketed as a clean-burning fuel for internal combustion engines. LPG's main components, propane (C3H8) and butane (C4H10), have different boiling points, -45°C and 0°C, respectively. Moderate temperature reduction or pressure increase liquefies LPG. These properties make it transportable as a less explosive liquid that can be easily regasified on-site for combustion.
