Abstract: Systems and processes for producing isomerized alkenes are disclosed. The systems mainly include an isomerization unit, a dehydrogenation unit, and a MTBE synthesis unit. A hydrocarbon stream is fed into the isomerization unit to form iso-alkanes in a sulfur free hydrocarbon stream. The sulfur free hydrocarbon stream is heated and then combined with a sulfur-containing hydrocarbon stream comprising sulfur containing compounds to form a reactant feed stream to the dehydrogenation unit. The iso-alkanes is dehydrogenated to form iso-alkenes. The formed iso-alkenes comprising isobutylene can be used as a feed stock for the MTBE synthesis unit.

Abstract: A method of producing methanol is disclosed. The method involves adding alkali to crude methanol and distilling the crude methanol in one or more distillation columns. The method also includes flowing a vapor side draw from one of the distillation columns, where the vapor side draw comprises fusel oil substantially free from alkali The fusel oil is recycled to a methanol synthesis reactor and/or a MTBE synthesis reactor.

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.
