HP HiGas

HP-HiGAS is a cutting-edge process intensification

technology developed by HPGRDC for gas
treatment applications and has huge potential in
the areas of carbon capture, natural gas

sweetening, refinery gases treatment, marine
scrubbers. The technology leads to significant

equipment size reduction over conventional
columns, along with other benefits such as low
capital cost and improved safety. The first-of-its

kind demonstration HP-HiGAS unit was set-up at
HPCL Visakh refinery for removal of H2S from

refinery fuel gas, which has achieved 10 times size
reduction vis-à-vis conventional column. HPCL is
currently setting a 24 KTPA demonstration HP-

HiGAS unit for CO2 capture from HGU process
streams at our Visakh Refinery. HPCL signed

Technology Partnership Agreement with KBR, USA
for global marketing & licensing of HP-HiGAS
Technology with a special focus on carbon capture

applications.

VPSA for CBG

HPGRDC developed indigenous HP-CBG VPSA technology for Biogas
purification based on vacuum pressure swing adsorption process. Novel

two-stage process leading to higher methane recovery of >99% with
specified CBG purity. Pilot plant is successfully operational at HPGRDC for
over 3 years with consistent performance. Development of next generation

adsorbent materials is in progress for overall efficiency improvement. HPCL
is now ready to design / supply HP-CBG VPSA technology to various

customers in India.
