Abstract
Isobutane and propane are separately charged to different catalytic dehydrogenation zones. The reaction products, including principally propylene and isobutylene, are combined, followed by separation of steam condensate, carbon dioxide and fuel gas from the mixture of effluents from the two separate dehydrogenation reaction zones. Propane and propylene are then separated from the isobutylene. The propylene product is recovered, and isobutylene is charged to an etherification reactor and there reacted with methanol to yield methyltertiarybutyl ether (MTBE). The etherification reactor effluent is fractionated to separate MTBE from n-butane and from isobutane. The latter is separated from n-butane and recycled to the isobutane dehydrogenation zone. Unreacted propane is also recovered and recycled.
