Mumbai – 20.06.2023
Hindustan Petroleum Corporation Limited (HPCL) is pleased to announce that its HP Green R&D Centre (HPGRDC) in Bengaluru has achieved a significant milestone by successfully completing the indigenization of Hydrogen Pressure Swing Adsorption (H2 PSA) Technology. This includes all major technical elements such as the adsorbent system, PLC system and program, and plant design. As a result, HPCL is now ready to offer comprehensive technology solutions to the industry.
The HP Green R&D Centre in Bengaluru has been at the forefront of cutting-edge research and development, catering to the evolving needs of the petroleum refining and energy industry. In just seven years since its inception, HPGRDC has commercialized 55 technologies and products and has been granted 167 patents.
A major technological breakthrough achieved by HPCL is the development of India's first indigenous H2 PSA Technology, widely used for hydrogen purification in refineries. This in-house technology was successfully demonstrated through the establishment of a commercial-scale Greenfield 6-bed H2 PSA unit in the Continuous Catalytic Reformer (CCR) block of HPCL's Visakh Refinery, with a feed capacity of 36,000 Nm3/hr. The unit has been operating successfully for the past eight years since its commissioning in 2015.
Leveraging its strong adsorption research facilities and expertise, HPCL has also developed efficient adsorbent systems for commercial H2 PSA units. Adsorbent replacement was successfully carried out in the commercial-scale 5-bed H2 PSA unit with a capacity of 33,400 Nm3/hr at the Mumbai refinery, as well as in the 10-bed H2 PSA unit with a capacity of 79,200 Nm3/hr. Both units have demonstrated excellent performance over the past five to seven years.
Furthermore, HPCL has developed a state-of-the-art Programmable Logic Controller (PLC) system and program, which serves as the heart of the H2 PSA technology. In a groundbreaking achievement, HPCL recently commissioned its indigenous PLC system and program at one of the existing H2 PSA units at the Visakh Refinery. Building on this success, HPCL is moving forward with replacing the PLC systems in its other H2 PSA units in refineries, with completion expected by 2023-24.
Drawing from its vast experience and capabilities gained through various indigenization efforts, HPCL is now poised to offer comprehensive Hydrogen PSA technology solutions. These solutions encompass new PSA unit designs, PLC systems, adsorbents, and technical services. The widespread adoption of this technology across the Indian refining sector will significantly contribute to the Government of India's Aatmanirbhar Bharat (Self-Reliant India) initiatives.
HPCL remains committed to driving innovation and sustainability in the energy industry while supporting the nation's vision of self-reliance.
