Abstract: A process for producing ethylene and at least one of butanol and an alkyl tert-butyl ether from field butane includes separating the field butane into an n-butane stream and an isobutane stream; cracking the n-butane stream to obtain a cracked product stream comprising n-butane, 1-butene, 2-butene, butadienes, or a combination comprising at least one of the foregoing; and at least one of the following: (1) separating the cracked product stream to obtain a butane stream and a butene stream, and reacting the butene stream with water to obtain a fuel additive comprising butanol, and (2) dehydrogenating the isobutane stream in a dehydrogenation unit to form an isobutene stream and reacting the isobutene stream with an aliphatic alcohol to produce an alkyl tert-butyl ether.
