Demonstration test result of High Pressure Acid gas Capture Technology (HiPACT)

The HiPACT technology (High Pressure Acid-gas Capture Technology), jointly developed by JGC and BASF, is an advanced CO2 capture technology that contributes to economical CCS (Carbon dioxide Capture and Storage) implementation. The demonstration test was conducted in INPEX's Koshijihara natural gas plant in Japan. HiPACT showed excellent performance in CO2 absorption; 20-27% reduction of solvent circulation rate and 10-20% savings in reboiler duty compared with OASE purple were achieved, keeping the CO2 specification at the absorber overhead unaffected. A case study suggests that HiPACT reduces CO2 recovery cost (AGRU + CO2 Compressor) by 25 to 35% over OASE purple.
