New Application Note on KOH Scrubbing of Acidic Gas has been released

K-Patents has released a new application note on KOH scrubbing of acidic gas. K-Patents Refractometer PR-23-GP-FM is used to control KOH solution make-up. Fresh KOH is added when it is depleted. 
An in-line measurement can ensure that there is no HF acid break through going to the flare.
