Natural gas or process gas dehydration at low pressures, low flow rates, and / or low temperatures can be very difficult. Most conventional salt-type absorbent desiccants are unable to adequately dry gas to low water content under these conditions. 4UF was developed to meet low dew point requirements when other desiccants or glycols cannot.
4UF can be used by itself or in combination with other grades of deliquescent desiccant, such as SP or 10BF Desiccant. In some applications, consumption is optimized when the process gas flows through the lower grade desiccant prior to the highly absorbent 4UF.
*4UF is also known as Gas Dry™ Ultimate
