Abstract: A method of producing a fuel additive includes passing a feed stream comprising C4 hydrocarbons through a first hydrogenation unit producing a first process stream; passing the first process stream through a distillation unit; withdrawing a 2-butene stream from the distillation unit: passing the 2-butene stream through a second hydrogenation unit producing a 1-butene stream; passing at least a portion of the 1-butene stream through a separation unit; and passing the 1-butene stream through a hydration unit producing the fuel additive.

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: 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.

Abstract: Systems and methods for processing a C3 and C4 hydrocarbon mixture have been disclosed. The C3 and C4 hydrocarbon mixture is separated to remove propane from C4 hydrocarbons. The resulting C4 hydrocarbons are then processed in an isomerization unit to produce additional isobutane. The isobutane of the isomerization unit effluent is dehydrogenated in a dehydrogenation unit to produce isobutene. The resulting isobutene is reacted with an alkanol to produce an alkyl tert-butyl ether.

Abstract: Systems and methods for integrated glycerol carbonate and/or urea production. This disclosure pertains to development of a process for production of glycerol carbonate and/or urea from ammonia, carbon dioxide and glycerol. The process integrates glycerol carbonate production into a urea production process. The urea produced in the production facility may be used to produce glycerol carbonate by reacting urea with glycerol. The ammonia generated by glycerol carbonate production may be recycled back to urea production. Unreacted urea from the glycerol carbonate production may be separated and recycled to the urea product stream. The systems and methods can reduce the cost for urea production and increase product value of the excessive glycerol produced from other chemical plants.
