Description:

The increasing availability of field butanes solves the problem of providing sufficient motor fuel oxygenates to meet the demands of the 1990 Clean Air Act. The field butanes can be isomerized to isobutane which is dehydrogenated to 0 isobutylene. The isobutylene is the feed for an ethers plant to make MTBE or ETBE. The selection of the dehydrogenation and etherification processes is critical. Dehydrogenation processes, such as CATOFIN7rM (for which ABB Lummus Crest acquired exclusive worldwide licensing rights from United Catalysts, Inc. when United Catalysts purchased the Houdry'" technologies from Air Products and Chemicals, Inc. in 1990) which are high in conversion and selectivity, have an economic advantage. High conversion in the dehydrogenation step provides a rich feed to the etherification process. If this step is also high in conversion, the recycle of unreacted C4's is minimal. The CATOFIN process can accept this recycle from etherification without removal of residual oxygenates or olefins. The economy of scale is significant for plants built in the max imum single train size of 32,000 barrels per day of MTBE.
