The Kansai Electric Power Co.,Inc.
has been promoting a wide range of research activities to suppress carbon dioxide (CO2),
which is considered to be one of the principal causes of global warming.
Our research themes include separation and recovery, fixation, and utilization of CO2.
Regarding the separation and recovery technology,
we have constructed a pilot plant at our Nanko Power Station.
This plant is equipped with a chemical absorption system to separate and recover CO2
from exhaust gas discharged from the thermal power station.
At this plant, we are currently evaluating the overall system performance,
together with approaches to system cost reduction.
This system that we developed is also being applied in a urea production plant
in Malaysia having a daily production capacity of 160 t.

Alkanolamines are used for the absorbing liquid.
To find higher performance absorbing liquid,
we are proceeding with research on various types of solvents using the CO2 absorbing test equipment installed in our General R&D Center.
The KS-1 absorbent we developed is the highest performance of the world.
So several plants were built.
