Equilibrum constant "K"

  • 1.  Equilibrum constant "K"

    I am starting new career as lab technician without much background in chemistry (Graduate industrial engineer).

    I am actually working at evaluating the efficiency of our absorption / stripping process and way or factor to play with if we have to improve it at economical cost.

    I would appreciate your help to have a link for a good material to calculate or evaluate the Equilibrium Constant "K" of Henry's Law ?

    Thank you

    If nothing is in Perry's, see if CRC's "Handbook of Chemistry and Physics" has anything.

    Do a search for "Compilation of Henry's Law Constants (version 4.0) for water as solvent" by R. Sander. It's a compilation that's been put together and is available online in a PDF. It also has conversion tables for Henry's Law Constants which is extremely helpful.

    The N.I.S.T. website is also a decent source for Henry's Law constants, however they're usually at STP.

    Without having taken a mass transfer or transport phenomena class, and if you've never ran or operated an absorption process I would caution looking at making adjustments to the process, and you will definitely want to run things by a ChemE. Depending on what you're stripping in your absorption process it can be dangerous to make adjustments that may allow harmful gases out, or flood a column.

    Hope that helps.
