I. Overview
It is mainly used to simulate the synthesis and decomposition of CO2 hydrate in soil (fine sand) under certain temperature and pressure conditions.
Device Features:
1. The reactor is designed with a water jacket layer and an insulation system, and is also designed with a cold water circulation system and a hot water circulation system, which can be used for low-temperature control of hydrate synthesis and heating control of hydrate decomposition.
2. The reactor is designed with 30 pressure measuring points, saturation measuring points, and temperature measuring points, which can monitor online the changes in the pressure field, saturation field, and temperature field in the soil.
3. The reactor is designed with a winch lifting system and a hydraulic cylinder. The winch is used for plate-shaped or strip-shaped structures in the soil body of the reactor to tilt them at a certain angle, and to measure the change in force online during the change in angle. The hydraulic cylinder and hydraulic station can tilt the reactor at a certain angle to simulate a certain formation dip angle.
II. Main Technical Parameters:
1. Model Specification: φ600×800mm
2. Maximum Operating Pressure: 2MPa
3. The model is pre-filled with 400-500mm high soil (fine sand), and a movable (pulley type) winch is installed on the top of the soil.
4. Operating Temperature: -5～40℃
5. Each soil body is designed with 30 sets of pressure measuring points, saturation measuring points, and temperature measuring points, which can form pressure field, temperature field, and saturation cloud maps.
