Carbon Capture and Liquefaction Unit
Visakhapatnam, India
Hindustan Petroleum
Scope of Work
The scope covers the engineering, procurement, and construction of the full carbon capture system. It includes COâ‚‚ absorption, amine regeneration, COâ‚‚ compression, liquefaction, bottling facilities, and associated Balance of Plants (BoP). The plant is based on a new gas-liquid absorption technology developed by HPCL R&D, known as HP-HiGAS, which applies Process Intensification principles using a Rotating Packed Bed (RPB) to enhance mass transfer efficiency and reduce equipment size.

Current Progress
Challenges & Excellence
As a demo cum commercial plant, this project presented the dual challenge of delivering a first-time technology at commercial standards. The adoption of Rotating Packed Bed (RPB) technology required close integration of design, procurement, and fabrication processes to achieve the intended size reduction, capital cost savings, and enhanced safety. NET’s execution has successfully aligned with HPCL’s innovation goals while ensuring engineering excellence, making this project a national benchmark in carbon capture implementation.
