The coordinates of DEAR air separation equipment with which two state parameters are arbitrary mainly depend on how to use them conveniently. The coordinates of
The DEAR air separation unit closes the purge valve, analysis valve, upper and lower valves of level gauge and heating valve of lower tower system. Open the upp
After several partial condensation of rising steam of DEAR air separation unit, nitrogen and a small amount of excess hydrogen are in the top of the tower (liqu
Due to the increase of cooling capacity released by circulating air in DEAR air separation unit, the cooling capacity released by the return gas in the cold sec
DEAR Air separation equipment also contains trace acetylene and hydrocarbons. Although adsorbed by acetylene absorber, its adsorptive efficiency can only reach
When the resistance between the groups of switching heat exchangers of DEAR air separation units is different, the gas will deflect and cause uneven gas flow di
The pressure of the lower tower is reduced due to the condensation of some gases, so that more air is "sucked in". Therefore, with the rise of the main cooling
For the 6000m3 / h DEAR air separation plant, the expansion amount is about 19.6% of the process air amount when producing gaseous products, and 27% of the proc
