Big Data Application of Deep Cold Air Separation Equipment

The load adjustment range of low pressure small air separation unit is related to the adjustment performance of the raw material compressor, the adjustment performance of the expander, the structural characteristics of the distillation tower and other factors. At present there are imported guide vane of the turbine air compressor flow adjustment range in 75-100%; adjustable nozzle of the turbine expander adjustment range can be in 65-100%. When oxygen is rich and the need to reduce oxygen produc...

Pressure test of piping in the cold box (1) The system adopts air pressure test, the medium is dry and oil-free air. And must be responsible for the package by a dedicated person partition, strict and careful inspection of the leakage of each part, no leakage is allowed. (2) Before the pressure test, the butt welds of the pipeline should have been checked and qualified, and the valve position holes of all safety valves and automatic valves in the switching process should be blocked with blind ...
