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
The average temperature difference is related to the relative flow direction of cold and hot fluids. The parallel flow of two fluids in the same direction is ca
The air from the cold end of the accumulator enters the lower tower through the automatic valve box (through-1 valve). During the start-up, the expander is expa
Large size gate valves and pneumatic control valves should be installed vertically to avoid deviation due to the heavy weight of the valve core, which will incr
