AI Technical Summary
In existing technologies, supercritical carbon dioxide transmission pipelines are prone to low-temperature damage and dry ice blockage when depressurized, and existing equipment is large in size and expensive.
By employing a combination of controller, temperature transmitter, and high-temperature gas supply valve, the pressure relief valve and high-temperature gas supply valve are controlled in real time through monitoring the pipeline temperature, thus preventing low-temperature damage and dry ice formation.
This improved the stability and security of the equipment while reducing the size and cost of the system.
