N2 Cryogenic plant deriming, dew point N2 Cryogenic plant deriming, dew point Gulmi (Chemical) (OP) 24 Jul 16 04:42 thread774-115300: deriming ASU plant Hi, if dew point after deriming is -41C, how adversely it can impact to operation? can we start up the unit not reaching required -60C dew point after deriming? RE: N2 Cryogenic plant deriming, dew point IRstuff (Aerospace) 24 Jul 16 16:22 Well, if it doesn't adversely affect operation, then why do the deriming in the first place? So, why do you do the deriming? The dew point tells you that you still have moisture in the system, as well as other contaminants that came with the moisture. TTFN (ta ta for now) I can do absolutely anything.
