Solid Bed Dehydrator – Pressure

By 24 September 2016

Generally, the adsorption capacity of a dry bed unit decreases as the pressure is lowered. If the dehydrators are operated well below the design pressure, the desiccant will have to work harder to remove the water and to maintain the desired effluent dew point. With the same volume of incoming gas, the increased gas velocity, occurring at the lower pressures, could also affect the effluent moisture content and damage the desiccant.
