GTC Technology has provided its low-temperature Isomalk-2 process technology for the successful start-up of a light naphtha isomerization unit at the Bharat Petroleum Corporation Ltd. (BPCL) refinery in Mumbai, India. The unit will produce an isomerate gasoline blend stock component. The overall process includes a naphtha hydrotreating and fractionation section, isomerization section and a first-of-a-kind GT-TDWC (Top Dividing Wall Column) installation.
This was a unique application with the dividing wall running from the top of the column. In this configuration, the column has two separate sets of condensing systems and offers a significant flexibility in terms of producing different levels of food grade hexane.
GTC has provided a single-source responsibility for process license, basic engineering design, catalysts and chemicals, equipment supply and process guarantees. GTC Technology, based in Houston, Texas, is a global licensor of aromatics and polyester intermediates processes, offering many novel and cutting-edge processes. These include Isomalk-2, Isomalk-3, Isomalk-4, GT-BTX PluS, GT-TolAlk and others.
