a 96t/day propylene recovery unit (PRU) are also outlined in the plans. Other auxiliary units being built under the project include two 113million tonne per year hydrogen generation units (HGUs), two 360t/day sulphur recovery units (SRUs) including tail gas treatment units (TGTUs), and a 36,000 tonne per year fuel gas pressure-swing adsorption (PSA) unit. A 300t/h non-hydro-processing sour-water stripper (SWS-I), a 185t/h hydro-processing sour-water stripper (SWS-II), two 540t/h amine regeneration units (ARUs), a 112,000tonne per year sulphur recovery LPG treating unit will also be installe Various existing units, including a naphtha hydro-treating unit, a continuous catalytic reformer and a diesel hydro-treating unit are also being revamped as part of the modernisation. Additionally, a duel fuel-powered captive power plant (CPP) built in 2003 The project will also involve the construction of a new utility system comprising a re-circulating sea cooling water system consisting of cooling tower cells and water pumps, as well as a demineralised water system featuring a new reverse osmosis (RO) system and water tanks. Technology upgrades at Visakh refinery VRMP will implement Honeywell UOP Penex™ process technology to produce a high-octane gasoline component called isomerate, and a Unicracking™ hydrocracking unit to produce cleaner burning diesel fuel. The Penex employs high-activity isomerisation and benzene impregnation catalysts from Honeywell UOP. Unicracking processes use highly effective catalysts to yield higher quantities of cleaner-burning fuels from a range of feedstock. The innovative configuration of the fractionation unit ensures effective separation of the products, while minimising capital costs and operating expenses. The two processes will significantly increase the capability of the refinery to deliver petrol and diesel in compliance with the new BS-VI clean fuels standards. "VRMP will expand the refining capacity of the Visakh refinery from 8.3million tonne per year to 15million tonne per year, while enabling the production of Bharat Stage-VI (BS-VI)-compliant fuels." The planned integration of innovative technologies will also enhance gross margins of the refinery by generating high-value transportation fuels from low-value raw materials. VRCFP (Visakh Refinery Clean Fuels Project) This project was implemented by the Projects Department at Visakh Refinery. This project is essentially to produce fuels for environment improvement at an estimated cost of Rs 16352 million with an FE component of Rs 2525 million. The project was approved by the Board on 30 April 2003. M/s EIL is the consultant for the project. Process licensors include M/s UOP, M/s Axens and M/s Belco. References Oil refineries
