What dew point will deliquescent desiccants deliver?
Deliquescent desiccants deliver what’s commonly called a dew point suppression. The most aggressive deliquescent desiccant, GasDry Max, will suppress the dew point by as much as 65F below the operating temperature of the gas. Keep in mind that he term pressure dew point is commonly misused in the natural gas industry. Pressure dew point is the temperature when condensation begins at line pressure. The measurement of water vapor in terms of pounds per million standard cubic feet (#/MMSCF) is not a pressure dew point. A moisture content measure measurement in #/MMSCF does not tell you at what temperature water will condense at line pressure. Pressure dew point is the measurement that conveys this information and is therefore often more useful in analyzing fuel gas and instrument gas dehydration applications, where preventing condensation is the goal.
