Honeywell today announced that Hindustan Petroleum Corporation Ltd. (HPCL) is using technologies from Honeywell UOP (Des Plaines, Ill.; www.uop.com) for the expansion and modernization of its refinery at Visakhapatnam in Andhra Pradesh on the southeast coast of India.
Included in the project are licensing, basic engineering design and other associated services for a Penex isomerization unit, which helps make cleaner burning high-octane gasoline, and a Unicracking hydrocracking unit to produce cleaner burning diesel fuel.
The Penex process upgrades light naphtha feedstock to produce isomerate, a cleaner gasoline blend-stock that does not contain benzene, aromatics or olefins. The process uses Honeywell UOP’s portfolio of proven, high-activity isomerization and benzene saturation catalysts.
The Unicracking process uses highly effective catalysts, unit design and reactor internals to produce higher yields of cleaner-burning fuels from a wider range of feedstocks. The unit’s fractionation section includes an innovative configuration to more efficiently separate the products, reducing capital costs and significantly lowering utilities and operating expense. In addition, the unit’s heavy polynuclear aromatics management allows the unit to achieve nearly 100% conversion throughout the entire cycle length.
Together, the two processes will significantly enhance HPCL’s ability to supply gasoline and diesel that meets the Indian government’s new Bharat Stage-VI clean fuels standard, and meets growing demand for those fuels. They also improve gross refining margins by converting low value feed stocks to high-value transportation fuels.
India’s gross domestic product currently is growing at 7 to 8%, driving robust growth in demand for gasoline — particularly as automobile sales increase – and diesel fuel, driven by growth in commercial and agricultural production. To meet tightening global emissions standards, the Indian government has proposed a 35-percent reduction in carbon emissions by 2030 by adopting Euro-IV fuel specifications by 2017 and BS-VI (roughly equivalent to the Euro-VI specification) by 2020.
