摘要
CO2过度排放所引起的温室效应已经对人类的生活造成了诸多不利影响。CO2地质封存技术作为一项有效的CO2处置技术,已经受到了越来越广泛的关注。研究了CO2在模拟深部盐水层溶液中的溶解度及溶解度随埋存深度(800~2800m)的变化规律。结果表明,在800~1700m埋深范围内,CO2溶解度随着盐水埋深的增加而减少;当埋深大于1700m时,CO2溶解度则随着盐水埋深的增加而增加。CO2溶解度随埋存深度的变化用方程进行了拟合,以此为基础预估了一定区域封存场地的CO2封存量。
The greenhouse effect caused by excessive CO2 emissions has led to many adverse effects on human life. As an effective CO2 disposal technology, CO2 geological storage technology has aroused more and more attention. The solubility of CO2 in simulated deep saline solution and its variation with burial depth(800~2 800 m)were studied. The results showed that, when the buried depth was in the range of 800~1 700 m, the solubility of CO2 decreased with the increase of buried depth. When the buried depth was greater than 1 700 m, the solubility of CO2 increased with the increase of saline depth. In addition, the change of CO2 solubility with burial depth could be fitted by the equation. And based on this equation, the storage capacity of CO2 in a certain area of stor. age site could be calculated.
