BHPV has entered into technical back up agreement with NUOVOPIGNONE, ITALY for design, engineering, manufacture and supply of Hydrocracker Reactors.
NUOVOPIGNONE is one of the most qualified suppliers of heavy wall reactors for Hydro- cracking, Hydro treating and similar refinery applications.
With the above back up from NP, BHPV supplied 3 Nos Hydrocracker Reactors to Indian Oil Corporation for their 6 Million tons new grass root refinery at Panipat.
The Hydrocracker reactors are highly critical equipments in the Refinery. The reactors require heavy forgings with internal strip cladding. These are ASME U2 code stamped equipments.
BHPV entered into full-fledged collaboration with BHEL / CE for design, manufacture, erection and commissioning of Industrial Boilers for process and captive power. The technology obtained from CE, USA has been improvised to suit Indian fuels with the support of BHEL’s vast experience and continuous R&D effort. BHPV has fully absorbed the technology from BHEL. A large number of highly efficient Boilers from BHEL / CE are operating successfully all over the world. With this back up, BHPV has more than thirty such installations to its credit.

Cryogenic Plants and Equipment
BHPV branched off into the manufacture of Cryogenic equipment in 1971. The move was prompted by BHPV’s growing awareness that India’s process industries were hopelessly dependent on imports for all Cryogenic Equipment. In collaboration with L’ Air Liquide of France, BHPV ventured into this technology-intensive field. In just a few years, BHPV has left its mark. In 1982, in the face of fierce international competition, it bagged a prestigious contract from Vizag Steel Plant to meet the entire cryogenic need of the plant.
BHPV’s range of Cryogenic Equipment include:
Air Separation Units of capacities ranging from 50Nm3/hr up to 2200 TPD to produce oxygen, nitrogen and argon. Nitrogen wash units for preparation of synthesis gas mixtures for the fertilizer units. Purge gas recovery units for separation of hydrogen from Purge gas of Ammonia plants using Naphtha or natural gas as feedstock. Storage tanks of horizontal and vertical designs starting from 500 liters up to 200,000 liters capacity to hold liquid oxygen, nitrogen & argon. Large field-erected cryogenic storage tanks of 200m3 to 10,000m3 capacity.
