Monitoring system of carbon dioxide geologic sequestration leakage

Abstract

The invention relates to a monitoring system of carbon dioxide geologic sequestration leakage. The monitoring system comprises a sample acquiring processing unit for acquiring sample gas from a CO2 geologic sequestration leakage point, wherein the sample gas is filtered, refrigerated and dried in the sample acquiring processing unit, and then enters an analysis detection unit after being dehydrated and dedusted; the analysis detection unit is used for detecting the sample gas, analyzing the CO2 concentration and transmitting the detection result to a programmable logic control unit; the programmable logic control unit is used for interacting information with a human-machine interface, transmitting a multi-sample point detection instruction to the sample acquiring processing unit according to the detection result of the analysis detection unit and the instruction transmitted by the human-machine interface, and transmitting the obtained detection data and image information to the data acquiring storing unit; and the data acquiring storing unit is used for transmitting the detection data and image information to the CO2 geologic sequestration monitoring centre through a wireless transmission unit to finish the monitoring. The monitoring system provided by the invention can be widely applied to the capturing and sequestration field of CO2.

Description

technical field [0001] The present invention relates to a monitoring system, in particular to a monitoring system for carbon dioxide (CO 2 ) Leakage monitoring and early warning and forecasting system in the process of geological storage. Background technique [0002] carbon dioxide (CO 2 ) capture and storage (carbon dioxide capture and storage, CCS) is one of the important strategies to deal with climate change, and is an important part of low-carbon economic policy. CCS technology is expected to reduce atmospheric CO 2 The growth rate of the concentration of greenhouse gases is equal to the purpose of slowing down global warming. Due to the complexity of geological structures and the long-term nature of CO2 geological storage, CO 2 The risk of leakage permeates CO2 capture and storage. Once carbon dioxide is leaked during the capture and storage process, not only will it not be able to effectively reduce the concentration of atmospheric carbon dioxide, but it will al...
