Abstract: Systems and methods for producing MTBE are disclosed. A C4 feed stream containing isobutylene and other C4 hydrocarbons is fed into a reactor unit for producing MTBE. The effluent of the reactor unit comprising MTBE is further processed to produce a MTBE product stream that comprises at least 90 wt. % MTBE. At least a portion of the MTBE product stream is then recycled back to the reactor unit.

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: 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 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.
