Honeywell said that state run Hindustan Petroleum Corporation Limited () has deployed technologies from Honeywell UOP for the expansion and modernisation of its refinery at in .

The overall project includes licensing, basic engineering design and other associated services for a Penex isomerisation unit, which helps make cleaner burning high-octane gasoline, and a unicracking hydrocracking unit to produce cleaner burning diesel fuel.

“HPCL chose these solutions from Honeywell UOP due to their superior economics and successful track record with these technologies,” said Steve Gimre, managing director, Honeywell UOP India in a statement.

“UOP has licensed more than 160 Penex units, and more than 220 Unicracking units – more than any other licensor in these applications,” he added.

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 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-percent conversion throughout the entire cycle length.

Together, the two processes will 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 percent, 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.

HPCL is a government of India Enterprise with a Navratna Status. HPCL owns and operates two coastal refineries at Mumbai and Visakhapatnam along with a joint venture refinery at Mangalore, and another at Bhatinda, Punjab. It also operates six cross-country pipelines along with an extensive network of terminals, depots, LPG bottling plants, lube filling plants and aviation service facilities.
