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.

Abstract: Systems and methods for processing a C3 and C4 hydrocarbon mixture have been disclosed. The C3 and C4 hydrocarbon mixture is first processed in an isomerization unit to isomerize n-butane to form isobutane. The resulting effluent stream from the isomerization unit comprising primarily isobutane and C3 hydrocarbons, collectively, is flowed into a separation unit configured to separate the effluent stream to form a C3 stream comprising C1 to C3 hydrocarbons and a C4 stream comprising primarily isobutane. The isobutane in the C4 stream is further dehydrogenated to form isobutene, which is further flowed into an MTBE synthesis unit as a feedstock for producing MTBE.

Abstract: A method for processing pentanes obtained from a DIB unit is disclosed. The process can include separating a first stream containing pentanes obtained from a DIB unit, in a separation column to obtain a second stream comprising iso-pentane and a third stream comprising n-pentane and neo-pentane; and subjecting the third stream to a butane isomerization unit producing a fourth stream containing iso-pentane, n-pentane, and neo-pentane.

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.
