Production <br /> There are 27 companies producing methyl-text-butyl ether (MTBE) at <br /> 32 facilities in the United States. Table 2 lists U S producers, <br /> plant locations, and plant capacities In 1992, 9 1 billion pounds <br /> of MTBE were produced in the United States During that same year, <br /> capacity was estimated at 11 6 billion pounds <br /> B Use <br /> ' The largest use for MTBE is as a gasoline additive, accounting <br /> for almost all U S consumption Small amounts of MTBE are used <br /> as a chemical intermediate to produce high purity isobutylene <br /> The estimated 1993 end-use pattern for MTBE reports that 100 <br /> percent of MTBE use was in gasoline additives (produced in SIC <br /> Code 2911, used in many industries) . <br /> C Trends <br /> The U 5 market for MTBE is expected to grow rapidly well into <br /> the 19905 This growth is due, in part, to Clean Air Act pro- <br /> visions regarding gasoline reformulation <br /> TABLE 2 U S Producers of MTBE <br /> Company Plant Location(s) Plant Capacity <br /> (in millions of pounds) <br /> Amoco Whiting, IN 285 <br /> Yorktown, VA 50 <br /> ARCO Chemical Channelview, TX 3, 610 <br /> Corpus Christi, TX 1,140 <br /> ARCO Petroleum Carson, CA 240 <br /> Ashland 011 Catlettsburg, KY 305 <br /> Champlin Refining Co Corpus Christi, TX 165 <br /> Chevron El Segundo, CA 190 <br /> Pascagoula, MS 200 <br /> Citgo Lake Charles, LA 255 <br /> ' Conoco, Inc Ponca City, OK 133a <br /> Westlake, LA 133a <br /> Crown Central Petroleum Pasadena, TX 285 <br /> Diamond Shamrock Sunray, TX 200 <br /> Enron LaPorte, TX 1,425 <br /> Exxon Chemical Baytown, TX 285 <br /> Fina Oil 6 Chemical Big Spring, TX 48 <br /> Fnday, August 16, 1996 4 25 PM <br />
