Description
Overview
GAOTek Portable Moisture Analyzer Manual is hooked up after the mole sieve dryer after the methanol injection, just before the fractionating cryogenic separator. This is a setup to log overnight the moisture content of the gas to evaluate the capacity and column switching times of the mole sieve dryer. Keeping the moisture content low has many benefits including a lessening need for thawing out the cryogenic separator to remove the accumulated ice.
