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 methods for producing MTBE without using a catalytic distillation column or a super fractionator have been disclosed. An optimum volume of methanol stream required to maximize MTBE production and reduce slippage of isobutylene to minimum acceptable values together with a crude C4 stream are flowed into a primary reaction unit that comprises a first reactor and a second reactor in parallel configured to produce maximum values of final MTBE volumes under higher or equal established purity commercial quality specifications levels. The combined effluent from the first reactor and the second reactor is split to form a first portion, a second portion and a third portion. The first portion is flowed to a third reactor configured to produce additional MTBE. The second portion is combined with an effluent from the third reactor for further separation. The third portion is recycled to the first reactor and/or second reactor.
