摘要
CCUS技术即CO_(2)气体的捕集、运输、利用即封存,是一种能够实现CO_(2)气体零排放的绿色环保高新技术,在该技术项目中难免发生CO_(2)气体的泄露;模拟CCUS技术中CO_(2)的泄露对地下层水质的影响,通过记录水系pH值、Ca^(2+)、Mg^(2+)、碱度、HCO 3-的变化,分析了CO_(2)气体持续泄露过程中各自的变化规律,同时建立了CCUS技术中CO_(2)气体封存的数学模型,研究表明CO_(2)泄露能够明显导致水质的变化,可以把水质的pH值、Ca^(2+)等不同元素的浓度数值来作为检测CCUS技术中CO_(2)气体泄露的敏感参数;同时采用CO_(2)气体封存的建模公式来判断CO_(2)封存量的变化,有助于判断CO_(2)的泄露情况。
CCUS is the capture,transportation,utilization and storage of CO_(2)gas,which is a green environmental protection high-tech that can achieve zero CO_(2)emissions.The leakage of CO_(2)gas is inevitable in this technical project.This paper simulates the impact of CO_(2)leakage on underground water quality in CCUS technology.By recording the changes of pH value,Ca^(2+),Mg^(2+),alkalinity and HCO 3-in the water system,and the change rules of CO_(2)gas in the process of continuous leakage were analyzed.The mathematical model of CO_(2)gas storage in CCUS was established.Studies have shown that CO_(2)leakage can significantly change water quality.The pH value of water quality and the concentration of Ca^(2+)and other elements can be used as sensitive parameters to detect CO_(2)leakage in CCUS process.At the same time,the modeling formula of CO_(2)gas storage is used to judge the change of CO_(2).It is helpful to judge the leakage of CO_(2).
