Sulzer GTC Technology’s NHT and Isomerization unit for the Bharat Petroleum Corporation, Ltd. (BPCL) refinery in Mumbai, India, has exceeded all performance expectations since start-up on July 8, 2017. The unit, utilizing low-temperature Isomalk-2℠ process technology, produces an isomerate gasoline blend stock component. The overall process includes a naphtha hydrotreating and fractionation section, and isomerization section.
The unit is among several isomerization units provided by the Sulzer GTC / Neftehim partnership. Additionally, this project is the first installation by Sulzer GTC of a top dividing wall column (GT-TDWC℠).
The project was a large and complex endeavor, with newer technologies (GT-TDWC℠, FGH production at high quality) under close scrutiny and a demanding schedule. Sulzer GTC met all of 56 guarantees for product specification and utility consumption. Additionally, the unit is operating at 10% over the capacity of the basic engineering package design.
Alok Saxena, Managing Director-Sulzer GTC India, Pradeep Pawar, Sulzer GTC Houston Project Manager, Manish Bhargava, Technical Director – Sulzer GTC Advanced Distillation Systems, Prabhat Kumar Jha, Sr. Process Engineer-Sulzer GTC India, and Ashishkumar Shah, Sr. Process/Technical Services Engineer-Sulzer GTC India, were each instrumental in the project’s success and BPCL’s satisfaction.
