Compensation of internal parameters of argon fraction of small air separation units

Compensation of internal parameters of argon fraction of small air separation units
By modifying the parameters within the argon fraction control block, the stability of the argon content of the argon fraction in the small air separation units at variable loads and at steady state has been effectively improved, providing a firm basis for increasing the argon extraction rate.

Small air separation units, large air separation units and liquid air separation plants in the distillation of the air separation tower, gas and liquid flow on the tower plate is very complex, must control the flow rate of gas. Too high or too low flow rate can spoil the working conditions of distillation. Liquid overhang is one of these abnormal conditions. In normal distillation, the liquid level on the tower plate is higher than the exit weir, and the liquid is not allowed to escape from the ...
