Abstract
An improved processing system of an oxygenate-containing feedstock for increased production or yield of light olefins. Such processing involves oxygenate conversion to olefins and subsequent cracking of heavier olefins wherein at least a portion of the products from each of the reactors is elevated in pressure, using a common compressor, prior to being routed to a common product fractionation and recovery section. The system further comprises acid gas removal means to remove acid gases from the cracked product gas and that the olefin cracking reactor is a moving bed reactor.
