The document summarizes a feasibility study conducted by Toshiba Corporation on applying carbon capture and storage (CCS) technology to a steel plant in China. It discusses two potential cases for installing a CCS facility at Shougang Jingtang Steel Works that would capture 300 tons of CO2 per day. Case 1 involves capturing CO2 from the plant's lime kiln flue gas, while Case 2 focuses on capturing CO2 from hot blast stove flue gas. Both cases evaluate using hot blast stove flue gas as a heat source for CO2 recovery. The presentation provides details on plant layout, economics evaluation, and outstanding issues for further investigation.

 Further investigation may be necessary, taking into consideration
variation in steel plant operation and flue gas composition.
 Detailed and careful planning of construction may be required, so
as not to disturb the normal production activity of the plant.
 Further performance improvement may be sought through
optimization and heat integration.
 Present proportion of CO2 capture is limited. Further scale-up
design would require more investigation on imposed constraints.
 Further investigation and clarification on CO2 offtake (EOR) usage
need to be conducted.

28. 28
 Concept of applying carbon capture technology to the
Chinese iron and steel industry has been illustrated.
 The study looked into matching of CO2 source and heat
source for CO2 recovery at Caofeidian Iron and Steel Plant.
Two possible cases for carbon capture plant were identified.
Both plant designs were developed and evaluated.
 Generic cost evaluation were conducted for the plant designs
developed. Owing to the competitive cost of capital, and the
use of heat sources available in the steel plant, cost of CO2
capture is relatively competitive compared to that of similar
size projects in other countries and sectors.
