One of principal element.Power plant, refinery, production of hydrocarbons factory, steel plant, cement plant and some other chemical plant burning coal,
During the fuel such as oil and natural gas, a large amount of carbon dioxide can be discharged into air, and carbon dioxide is greenhouse gases,
Its in an atmosphere concentration raising can make weather balance be seriously damaged.
Carbon dioxide geological storage, just refers to and the carbon dioxide of these plant emissions is separated and collected, not to big
It is discharged in gas, second is that being injected into suitable deep geology structure, permanently buries underground, so can greatly subtract
The discharge capacity of few carbon dioxide is the powerful mean for coping with global warming.
Carbon dioxide geological storage is mostly that underground is injected in the form of supercritical fluid under conditions of high temperature and pressure.

Greatly.The development and utilization of hot dry rock, mainly using underground high temperature but lack the rock of fluid due to low-porosity and permeability
The heat stored in stone (body), needs to be formed enhanced geothermal system (Enhanced Geothermal by artificial fracturing
System it) can just be exploited.Generally use high-pressure working medium injection, the heat exchange of pressure break rock, hole, the mode for taking heat out of are opened
It adopts.This means that the development and utilization of hot dry rock, investment of equipment are very big.If can be improved the power generation effect of downstream electricity generation system
Rate can then significantly reduce the initial cost of whole system.
Usually there are two types of approach for the promotion of electricity generation system generating efficiency, and one is the main ginsengs such as the temperature for promoting power generation cycle
Number, it is another then be use new and effective power cycle form.For hot dry rock power generation, the temperature of power generation cycle is promoted
Degree, is limited by the limitation of local geographical conditions and the limitation of hot dry rock mining depth, difficulty is larger.So using new and effective
Power cycle form, such as supercritical carbon dioxide generation technology, then be promoted hot dry rock electricity generation system efficiency one kind it is important
Approach.
Consider in conjunction with above two technology, if the process and overcritical titanium dioxide that inject carbon dioxide into underground and seal up for safekeeping
The process of carbon hot dry rock power generation reasonably merges, then the energy consumption of carbon dioxide sequestration process not only can be significantly reduced, but also can mention
The efficiency of hot dry rock power generation is risen, the investment of equipment of hot dry rock power generation unit generated energy is reduced.
However through investigating, although carbon dioxide geologic sequestration technology and hot dry rock generation technology simple at present has centainly
Development, but rarely have the two to organically combine, the correlative study of comprehensive utilization, therefore, it is also desirable to a large amount of original sex work.
