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.

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.

A process for producing cumene and/or ethylbenzene from a mixed hydrocarbon feedstream comprising subjecting C6 cut separated from said mixed hydrocarbon feedstream to aromatization to provide an aromatization product stream and subjecting the thus obtained aromatization product stream to alkylation to produce an alkylated aromatic stream.
