INTEGRATED PROCESS FOR THE SIMULTANEOUS PRODUCTION OF ALKYL TERT-BUTYL ETHERS AND 1-BUTENE

摘要

An integrated process for the simultaneous production of alkyl tert-butyl ethers and 1-butene, comprising feeding a C4 hydrocarbon stream to an etherification unit and recycling the remaining stream to the same unit after possible separation of the 1-butene and treatment in an isomerization section to convert the remaining butenes into isobutene, a molecular sieve separation unit operating with the hydrocarbons in the vapour phase being incorporated into the cycle.
