Gas supplementation device for ultrahigh-pressure experimental process

Abstract

The invention relates to a gas supplementation device for an ultrahigh-pressure experimental process. The device comprises a high-pressure storage tank kettle body, a gas inlet pipe, a pressure stabilization and reduction gauge, a gas outlet pipe and a pressure indicator, wherein the gas inlet pipe and the gas outlet pipe are arranged at the top end of the high-pressure storage tank kettle body; a joint connected with a booster pump is arranged at the starting end of the gas inlet pipe; a gas inlet valve is arranged on the gas inlet pipe; a gas outlet valve is arranged on the gas outlet pipe; the gas inlet end of the pressure stabilization and reduction gauge is connected with the gas outlet valve, and the gas outlet end of the pressure stabilization and reduction gauge is connected with the gas outlet pipe; a joint is arranged at the tail end of the gas outlet pipe; a through hole is formed in the top end of the high-pressure storage tank kettle body; a pressure sensor is packaged in the through hole; the pressure indicator is arranged on the lateral surface of the high-pressure storage tank kettle body; the pressure sensor is connected with the pressure indicator through a signal wire. According to the device, gas can be stably supplemented into a high-temperature high-pressure reaction kettle; the device is wide in applied pressure range and particularly applicable to the supplementation of foreign gas in a trace foreign gas-containing ultrahigh-pressure corrosion experimental process.

Description

technical field [0001] The invention belongs to the field of corrosion experiment devices, and in particular relates to a device for supplementing gas during an ultra-high pressure experiment, which is used for stably supplementing gas into a high-temperature and high-pressure reactor during the ultra-high pressure experiment. Background technique [0002] Carbon capture and storage (CCS) technology is a cutting-edge technology with great potential for mitigating greenhouse gas emissions. This technology is to capture CO 2 Injecting oil and gas wells to enhance oil and gas recovery (CO 2 -EOR), which has been applied in the United States for more than 30 years, while domestic PetroChina and Sinopec have carried out the use of CO in many oil and gas fields 2 Pilot experiments to enhance oil recovery have achieved good results. CO 2 transported as CO 2 The intermediate hub from the capture site to the storage site is one of the key technologies for carbon sequestration. ...

Problems solved by technology

However, boosting with a booster pump is a process in which the pressure continues to rise. After reaching the set pressure value, the pressure cannot be kept stable.

Therefore, it is not feasible to directly use a booster pump to continuously replenish impurity gas or maintain a stable pressure
