Description
Technical field
It is the present invention relates to a kind of collecting carbonic anhydride and the integrated method of mineralising, in particular to a kind of using containing bittern water
Combine the method for trapping mineralization of carbon dioxide with solid waste.
Background technique
International Energy Agency report proposes CO2Capturing and seal up for safekeeping (CCS) technology is effective control CO2Discharge three big technologies it
One, plan for the United Nations's the year two thousand fifty by global CO2Concentration controls the contribution degree in the blueprint offer 19% of 450ppm, and predicts complete
The CO that ball will establish 3400 CCS projects and form 5,810,000,000,000 dollars to the year two thousand fifty2Industry.In the latest 20 years, countries in the world government
Fall over each other to subsidize CCS technical research, establishes research and development centre and demonstrative project with university and business tie-up, development technique of trying to be the first patent accounts for
Lead market forward position.
The invention patent proposes a kind of new integrated method of collecting carbonic anhydride mineralising, and the method process is simple, instead
It by two step organic combinations of carbon capture and carbon sequestration, should be combined into one rapidly, enrich the choice of technology of carbon emission reduction.Using
The method of the trapping carbon dioxide containing bittern water etc. has the advantage that
1) to be stored containing bittern water as Absorption of Medium, with the property from a wealth of sources on raw material, and, contain bittern water, sea
Water, salt pan waste water and industrial wastewater all contain the similar decarburization carbon sequestration factor, can be used as the substitution containing bittern water, favorably
In adaptation to local conditions using this technique, the applicability of this method is improved.
2) lower using saliferous brine mineralising efficiency merely, saliferous brine ph can be improved using solid waste, promote
Carbon dioxide conversion and absorption, at the same time using solid waste using industrial bulk solid waste (such as power plant waste,
Steel mill residue, cement plant residue, mining plants tailing) raw material is done, also realize the two-win of waste utilization and environmental protection；
3) a kind of that permanent and environment friend is realized using the method containing bittern water and solid waste joint trapping carbon dioxide
It seals up for safekeeping well, No leakage is monitored without the later period, compared with geological storage, is reduced risk and is easy by public well-established；
4) carbonation reaction for trapping carbon dioxide is exothermic reaction, can theoretically reduce the demand to heat；
5) this method is to some countries and regions that can not find suitable geological storage stratum or due to hypertelorism pipeline
Conveying pollution sources at high cost has good applicability；
6) a variety of products with economic value are generated during joint trapping carbon dioxide, a kind of use can be subsidized
The processing cost of the trapping carbon dioxide containing bittern water, and the potential higher economic benefit of creation forms industrial chain.
A kind of existing use can realize following target containing the method for bittern water and solid waste joint trapping carbon dioxide:
1) it is the necessary condition that carbonation process is gone on smoothly that saliferous aqueous salt brine, which keeps certain basicity,.It is normal in room temperature
Pressure, the suitable pH value range of decarburization containing bittern water is 8~10, and the excessively high generation that will lead to non-targeted precipitated product of pH value is made
At the dual waste of carbon sequestration medium and solution basicity.The capturing ability of carbon dioxide drops in the too low then saliferous aqueous salt brine of pH value
It is low, therefore we are adjusted pH value by the way of adding saliferous calcium ions and magnesium ions solid waste, in trapping carbon dioxide
It can maintain the suitable alkalinity of reaction system well in the process, guarantee that trapping process is gone on smoothly
2) pass through optimization solid waste and feed ratio containing bittern water, alkalinity additive type, additive concentration, reaction temperature
The parameters such as degree carry out process intensification to the trapping carbon dioxide containing bittern water, improve process economics.
3) carbon sequestration product is calcium carbonate and magnesium carbonate, is not easily decomposed in a natural environment and can be used as building materials etc. and utilizes, and realizes ring
Border is friendly and reduces cost.
