An experimental device for monitoring the kinetics of carbon dioxide, salt water and rock reactions

Abstract

The invention relates to an experimental device, to be specific, relates to a carbon dioxide, saline water, rock reaction kinetics monitoring experimental device. The above mentioned experimental device comprises a computer, a broadband light source, and a spectral demodulator. The broadband light source is connected with an input end of a 1*4 optical fiber coupler by a common single-mode fiber, and the four output ends of the 1*4 optical fiber coupler are connected with one end of a fiber bragg grating, one end of a micro-structure optical fiber surface plasma resonance sensor, one end of a panda type polarization-maintaining optical fiber temperature sensor, and one end of an elliptical core polarization-maintaining optical fiber pressure sensor by the common single-mode fibers, and the other ends of the above mentioned sensors are connected with four input ends of a 4*1 optical fiber coupler by the single-mode fibers. The output end of the 4*1 optical fiber coupler is connected with the spectral demodulator by the common single-mode fiber, and the spectral demodulator is connected with the computer by a data line. The 1*4 optical fiber coupler and the 4*1 optical fiber coupler are disposed in a fixing rack. The fiber bragg grating is attached to a cantilever beam, which is fixedly disposed on the fixing rack.

Description

[0001] Technical field: [0002] The invention relates to an experimental device, in particular to an experimental device for monitoring the reaction kinetics of carbon dioxide, salt water and rock. [0003] Background technique: [0004] In the context of global climate change, the reduction of greenhouse gas emissions, especially carbon dioxide, has become the focus of attention, and large-scale carbon dioxide capture and storage has become one of the choices carefully considered by many government agencies and industrial sectors around the world. Geological storage of carbon dioxide, especially in deep saline aquifers, is one of the most effective and promising options for its natural storage. According to the assessment report of the International Energy Agency (IEA) and the Intergovernmental Panel on Climate Change (IPCC), the global Carbon dioxide reserves in the saline layer can reach 400-10000Gt. Carbon dioxide sequestration in deep saline aquifers is an emerging geolo...
