Description
Technical field
Environmental protection equipment technical field is the utility model is related to, more particularly to one kind is adapted in CCS technologies CO after burning2Catch
Collection method uses absorption-regenerator of the continuous collecting carbon dioxide from fuel gas of hydrate.
Background technology
Climate change has turned into one of the problem of influence human survival and development, and the carbon dioxide of industrial discharge is considered as
It is the main reason for causing climate warming, China is as developing country maximum in the world, the primary energy based on coal
With the secondary energy sources structure based on thermal power generation, with increasing rapidly for economic total volume, the CO of primary energy and secondary energy sources2
Discharge, which has, increases the characteristics of fast, total amount is big.And the high throwing of current carbon emission reduction and CCS the or CCUS technologies of reply climate change
Money, the operation grade of high trapping cost become the serious hindrance of popularization and application, the research of existing CCS or CCUS technologies and
Demonstration Application, which is concentrated mainly on, must separate except high concentration CO2Coal chemical industry, synthesis gas and coal electrical domain, and coal electrical domain collection
In with IGCC coal gasifications, integrated gas-steam combined cycle power plant（IGCC）In the application of technology.
