CO2 enhanced oil recovery
There are various ways to utilize CO2, such as chemical use (urea, methanol), Enhanced Oil Recovery (EOR), and Enhanced Coal Bed Methane Recovery (ECBM). Of these, EOR is attracting attention as a technology that enables both the prevention of global warming by storing the CO2 and the tertiary recovery of crude oil at the same time.
The EOR collects CO2 emissions from power plants and factories, sends the CO2 via pipelines to the oil fields, inserts the CO2 to the oil reservoir of the oil fields, and recovers the crude oil remaining underground. The method dramatically increases the recovery rate of crude oil from what used to be 20 ~ 30%.
The MHI CO2 recovery process utilizes "KS-1™" an advanced hindered amine solvent, in conjunction with a set of proprietary equipment. The method is based on advanced and proven technologies for recovering CO2 from various sources of flue gas.
