With the continuous development of industrial technology and the improvement of automation level, the dcs system has just been widely used in the air
Compared to heads, little research has been carried out on deflectors because their performance is strongly influenced by the fluid conditions at the
It has been proven that the valve can be closed for a long time, but it is important to pay attention to the analysis point at the crude argon liquid
The argon fraction analysis point, i.e. the oxygen content in the argon fraction, is mainly controlled by the variable folding function block and the
The main tower working conditions are stable to ensure that the argon extraction rate is improved, in fact, to ensure that the argon fraction is stabl
The frequency and magnitude of variable loads are specified for small air separation unit , and the amount of crude argon tower load is increased at h
The crude argon tower is closely related to the main tower distillation working conditions, mutual constraints, only when the main tower working condi
The argon enrichment zone moves up, the oxygen content in the argon fraction is too high, and the crude argon tower, in addition to the increased oxyg
