Abstract

The invention discloses an experimental method and device for measuring a diffusion coefficient of CO2 in water. The experimental device adopts a fixed diffusion distance and mainly comprises a data acquisition system, a constant temperature heating system, a pH meter probe, a diffusion kettle, a pressure sensor, a temperature probe and the like, wherein the pH meter probe is installed on a lower end cover of the diffusion kettle, the pressure sensor is installed on an upper end cover, one end of the temperature probe is connected with a heating coil outside the diffusion kettle, and the other end of the temperature probe is connected with the constant temperature heating system. When an experiment is performed in the diffusion kettle, the diffusion kettle is installed on a bearing and is turned to simulate a tilted stratum, pressure is utilized to calculate initial concentration of the CO2 according to an ideal gas equation, the hydrolysis amount of the CO2 is calculated according to a pH value acquired by the data acquisition system, a fitted curve of the CO2 hydrolysis amount and time square root is drawn to obtain slope k, and the diffusion coefficient D is calculated according to a calculation model.

Description

technical field

[0001] The present invention relates to CO 2 Sequestration potential technical field, is a measure of CO 2 Experimental method and apparatus for the diffusion coefficient in water, especially for CO 2 Experimental method and device for measuring diffusion coefficient parameters during storage. Background technique

[0002] At present, people's demands for energy mainly rely on the burning of fossil fuels, and the reduction of greenhouse gas emissions has become the focus of human attention. China has become the world's second largest energy consumer after the United States, and it has undertaken greenhouse gas emission reduction obligations since 2013. my country's carbon emissions are increasing every year, and the emissions will soon surpass that of the United States. Proceeding from the national conditions of our country, actively develop CO 2 Underground storage research is very important.

[0003] The technology of capturing, storing and utilizing ...
