Abstract: Systems and methods for producing MTBE and 1-butene are disclosed. A crude C4 hydrocarbon stream is obtained by removing butadiene from a C4 hydrocarbon mixture of a hydrocarbon cracking unit. The crude C4 hydrocarbon stream is then distilled to form (a) a first distillate stream comprising isobutylene, isobutane, 1-butene, or combinations thereof and (b) a first bottom stream comprising 2-butene, n-butane, a deactivating compound for catalyst of MTBE synthesis. The first distillate stream is then flowed to a MTBE synthesis unit to produce via reaction with methanol. The raffinate from the MTBE synthesis unit comprising isobutane and 1-butene is further separated in a distillation column to produce 1-butene.

Abstract: A method for producing methanol includes feeding a synthesis gas stream to a methanol production assembly; feeding an off gas stream including hydrogen to the methanol production assembly; feeding a CO2 stream to the methanol production assembly; and reacting the synthesis gas stream and the CO2 stream in the methanol production assembly to produce methanol, wherein the method further includes reacting the off gas stream with the synthesis gas stream and the CO2 stream in the methanol production assembly to produce methanol, or feeding a reforming feed stream and the off gas stream including hydrogen to a reforming portion of the methanol production assembly to form the synthesis gas stream.

Abstract: Systems and methods for processing crude methanol are disclosed. A crude methanol stream, comprising methanol and paraffin wax, is produced from syngas (carbon monoxide, carbon dioxide, and hydrogen). The crude methanol stream is cooled to form a partially condensed crude methanol stream, which is further separated in a vapor-liquid separator to form a liquid stream and a gas stream. The liquid stream is further cooled in a dewaxing unit to remove paraffin wax. The dewaxing unit includes two or more cooling units arranged in parallel such that when one of the cooling units is offline for cleaning, the methanol system does not need to be shut down.
