AI Technical Summary

Technical Problem

Existing gas storage facilities have high investment costs, high energy consumption, and high maintenance costs for gas produced. They also require external heat sources, cannot effectively reduce the water dew point of the produced gas, and are prone to ice blockage, which affects the operation of the site.

Method used

A gas-liquid separation system is adopted, including a main gas extraction pipe, a gas-liquid separation container, and a throttling component. After the gas is cooled by the throttling valve, the liquid phase is separated. The liquid phase exchanges heat with the high-temperature gas phase to achieve self-circulation dehydration, which does not require an external heat source or adsorbent, thus simplifying the system structure.

Benefits of technology

It achieves low-cost, low-energy gas-liquid separation, reduces equipment investment and maintenance costs, ensures that the dew point of the extracted gas and water meets the requirements for external transmission, avoids ice blockage problems, and has a simple system structure and is easy to operate, making it suitable for various types of gas storage facilities.
