Problems with ultra-high pressure nitrogen pumps
Thread Content
Should the cooling exhaust pipeline of the ultra-high pressure nitrogen pump used in gasification be vented on-site or returned to the liquid nitrogen tank? This post was last edited by xuqinger on 2009-2-8 at 10:02.]
1. The small pre-cooling valve line located after the nitrogen pump outlet valve (which can be a check valve) should be connected to an on-site vaporization and venting system; it should be closed after pre-cooling. 2. The return line (used for pressure regulation during operation) located before the nitrogen pump outlet valve (which can be a check valve) should lead back to the liquid nitrogen tank
Can’t the second solution on the 2nd floor cause overpressure in the liquid nitrogen tank?
