Abstract: A method for the production of a fuel additive includes passing a hydrocarbon stream comprising crude mixed C4 hydrocarbons through a first hydrogenation unit to produce a first product stream; passing the first product stream from the first hydrogenation unit to a methyl tert-butyl ether synthesis unit forming methyl tert-butyl ether and a byproduct stream; passing the byproduct stream through a first distillation unit to separate the byproduct stream into a first 1-butene stream, an isobutane stream, and a 2-butene and n-butane stream; forming a second product stream by passing the 2-butene and n-butane stream to a selective conversion unit; passing the second product stream into a second distillation unit to form an n-butane stream and a second 1-butene stream; passing the second 1-butene stream to a fuel additive production unit; and passing the first 1-butene stream to the fuel additive production unit to form the fuel additive.

Abstract: A method of producing a fuel additive includes producing a first product stream comprising butadiene by passing a feed stream comprising C4 hydrocarbons through a steam cracker; transforming greater than or equal to 90 weight % of the butadiene in the first product stream into a second product stream by passing the first product stream through a first hydrogenation unit, wherein the second product stream comprises 1-butene, 2-butene, n-butane, isobutylene, isobutane, or a combination thereof; and converting the second product stream into the fuel additive by passing the second product stream through a fuel additive synthesis unit with an acid catalyst.

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: Systems and methods of dehydrogenating a hydrocarbon in a fixed bed dehydrogenation unit. A method for dehydrogenating a hydrocarbon is applied to a fixed bed reactor. The hydrocarbon flows to a fixed bed reactor to be dehydrogenated in presence of a catalyst in the fixed bed reactor. The catalyst in the fixed bed reactor is then regenerated. The period for dehydrogenation, the period for catalyst regeneration and the period for total slack time are controlled such that total slack time is less than both half of the period for dehydrogenation and half of the period for regeneration. One of the advantages of the process comes from optimization of the slack time, thereby increasing the catalyst utilization rate and number of reactors concurrently online.

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.
