【摘要】 将CO2注入海底已经成为目前碳封存的一种有效方式,而CO2海底封存泄漏会引起pH降低造成海水酸化,改变海水化学环境及海洋生态系统等。本文分析并建立了含有缓冲项的CO2与pH之间换算的动态数值模型,并针对CO2海底封存泄漏对pH的影响做了模拟实验研究,通过实验验证模型的可行性并完善数值模型,旨在为中国CO2海底封存风险控制研究工作提供科学依据。更多还原

【Abstract】 Injection of CO2 into the seabed will become an effective way of carbon sequestration at present,whereas the CO2 leakage can cause the decrease of pH and the acidification of sea water,and then change the chemical environment in sea water,the marine ecosystem,etc.In the paper,the dynamic numerical model which contains the conversion between CO2 and pH of cushion item was analyzed and established.The experimental studies on influence of leakage of CO2 sequestration seabed towards pH,the feasibility of model and perfect of the numerical model were made.The results provided the scientific bases for the risk of control research on Chinese CO2 storage undersea.更多还原
