Patent # 7,115,791
[585/640 ; 585/501; 585/639; 585/956]
A process for controlling an oxygenates to olefin reactor is disclosed which comprises: contacting oxygenate-containing feedstock,e.g.,methanol,in a reaction zone in the presence of a molecular sieve oxygenate to olefins conversion catalyst under conditions sufficient to provide an olefins-containing effluent containing alkyl alcohol and dialkyl ether,e.g.,methanol and dimethyl ether; analyzing a single gas phase of the effluent determine alkyl alcohol concentration and dialkyl ether concentration; and adjusting reactor conditions,e.g.,WHSV,as a function of alkyl alcohol concentration and dialkyl ether concentration,as necessary to provide a substantially consistent effluent composition. A corresponding apparatus for carrying out the process is also provided.
