AM-01-24 CONTINUE PRODUCING PREMIUM BLENDSTOCKS

Description:

Changes in the gasoline pool from MTBE removal can be compensated for by increased use of other blending stocks, for example, alkylate and isomerate, which are high-octane paraffinic blendstocks. If oxygenates are still required in gasoline, ethanol use will increase; however, the higher vapor pressure of ethanol will have to be mitigated. The increased alkylate demand can be met by several approaches, including the installation of new alkylation units or revamping existing MTBE units to the UOP Indirect Alkylation (InAlk) process. The purpose of this paper is to discuss several commercial MTBE revamps to the InAlk process.
