[bold]degasifier unit??[/bold]

(OP)
do any one know how to get henry's law constant if my system is 0.2 bar with 43o[/script]C.
u see i'm trying to calculate the efficiency of my degasifier unit, because the output of CO2 is only 21ppm and it should be less than 10 ppm. my water flow is 66m3/hr and air rate is 44000Nm3/hr. oh yeah what is the different between Nm3/hr and m3/hr??
please reply to me ASAP
thank you

Try this compliments of Uncle Sam:

Although there are several other internet sources for Henry's data, NIST is often the best free general source.

also FYI, Nm3 is a unit of measure for volume of a gas at standard temperature and pressure conditions. When using Aspen-plus and other simulation engines, standard volume flows (SCFM, SCMH, etc) are units of measure for moleflow.

To troubleshoot this will take a bit more information.  Suggest you look at the Jaeger website www.jaeger.com

First guess is you are not getting enough stripping air through the column but column diameter and packing depth all play a role as does proper air and water distribution.  Short circuiting can really hurt tower performance.
