CO2 Capture Plant




CO<sub>2</sub> Capture Plant
Mitsubishi Heavy Industries Engineering, together with Kansai Electric Power Co., have already established and commercialized its own post combustion CO2 capture technology, so called KM-CDR Process™.

KM-CDR Process™ , with own developed unique amine solvent (KS-1™), has been adopted for thirteen (13) commercial plants all over the world (as of Feb. 2019), which has several outstanding features as follows;

  • Can be applied to various types of flue gas sources
  • Advanced energy saving process – significant operation cost saving
  • Highly efficient proprietary solvent (KS-1™), with the lowest energy consumption and the least degradation

Process Flow

Exhaust gas containing CO₂ is cooled in an exhaust gas cooling tower, then exposed in the absorption tower to alkaline KS-1™ absorbent liquid, which absorbs the CO₂ in the exhaust gas. Absorbent liquid containing a high concentration of CO₂ is sent to the regeneration tower, where it is heated with steam to release and regenerate the CO₂. The regenerated absorption liquid is returned to the absorption tower, where it is reused. This process can recover more than 90% of the CO₂ contained in the target gas (with a purity of more than 99.9% by volume), and also reduces steam consumption thanks to our original energy-saving regeneration system.

Process Flow
  1. Cool the exhaust gas to the specified temperature.
  2. Exhaust gas is supplied to the bottom of the cooling tower, where it rises up through the internal filler.
  3. KS-1™ absorbent liquid is scattered from the top of the filler, and recovers CO₂ in the exhaust gas.
  4. KS-1™ absorbent liquid that has absorbed CO₂ is sent to the regeneration tower.
  5. CO₂ dissolved in the KS-1™ absorbent liquid is recovered in the regeneration tower.

Applications of CO₂

  • Chemical applications (increased production of urea, methanol)
  • General applications (dry ice for cooling, etc.)
  • Enhanced Oil Recovery (EOR)

Enhanced Oil Recovery (EOR)

Enhanced Oil Recovery (EOR)

There are many different applications for CO₂, but Enhanced Oil Recovery (EOR) in particular has gained attention as a technology that can simultaneously help prevent global warming while increasing the production of crude oil, by means of CO₂ storage.

This approach is used to recover CO₂ exhausted from power plants and factories and send it to oil fields by pipeline, etc., inject the CO₂ into the oil-bearing layer of the oil field, and recover crude oil left underground. This dramatically increases the recovery rate of crude oil, only 20% to 30% of which can be recovered conventionally.

Furthermore, the compressed CO₂ can be stored in the ground as is, thus significantly helping to prevent global warming.
