n-Butane

Use

n-Butane can be obtained from natural gas and from refinery hydro cracker streams. Most of the n-butane goes into fuel additive uses. The major chemical use is as a feedstock for ethylene production by cracking . The other important chemical uses for butane are in oxidation to acetic acid and in the production of maleic anhydride. In the past, butane also was the main feedstock for the production of butadiene by dehydrogenation, but it has been replaced by coproduct butadiene obtained from ethylene production. Ethylene. The largest potential chemical market for n-butane is in steam cracking to ethylene and coproducts. n-Butane is a supplemental feedstock for olefin plants and has accounted for 1-4 percent of total ethylene production for most years since 1970. It can be used at up to 10-15 percent ofthe total feed in ethane/propane crackers with no major modifications . n-Butane can also be used as a supplemental feed at as high as 20-30 percent in heavy naphtha crackers. The consumption of C4S has fluctuated considerably from year to year since 1970, depending on the relative price ofbutane and other feedstocks. The yield of ethylene is only 36-40 percent, with the other products including methane, propylene, ethane, and butadiene, acetylene, and butylenes. About 2-3 billion Ib of butane are consumed annually to produce ethylene.
