A good recovery

Samsung Engineering is to deploy Mitsubishi Heavy Industries’ CO2 recovery technology at the site of a petrochemical company in Vietnam.


Samsung Engineering is to deploy Mitsubishi Heavy Industries’ (MHI) CO2 recovery technology at the site of a petrochemical company in Vietnam.


The CO2 recovery facility, which will be built at the Phu My Fertiliser Plant of PetroVietnam Fertilizer and Chemicals Corporation (PVFCCo) near Ho Chi Minh City, is slated to go on-stream in early 2011, and expected to increase urea production at the plant by 60,000 tons per year.


The MHI technology recovers CO2 from flue gas emitted during the urea fertiliser production process, which uses natural gas as fuel, and provides the captured CO2 as feedstock for urea synthesis.


The CO2 contained in the flue gas emitted from the primary reformer during the ammonia production process will be absorbed into MHI’s KS-1 proprietary solvent, which MHI jointly developed with Kansai Electric Power Company.


The CO2 is then synthesised with ammonia for use as feedstock for urea production. The technology can recover approximately 90 per cent of the CO2 in flue gas.


Outside Japan, MHI delivered its first CO2 recovery facility to a fertiliser production plant in Malaysia in 1999.


To date, the company has seen the technology used at a total of eight fertiliser production plants around the world, including facilities in India, the United Arab Emirates, Bahrain and Japan.


In addition to urea production, CO2 recovery technology can be used to produce methanol and dimethyl ether (DME).
