Bransands biogas dehumidifier set up in works
PRODUCT OVERVIEW: 

Digester produced biogas is 100% water saturated. The naturally cooling biogas, moving from the digester to the point of use will release large amounts of water into the gas pipework system. This has the potential to corrode pipework and damage mechanical plant.

A standard biogas dehumidifier consists of 2 tube heat exchangers. Including a biogas to biogas heat exchanger for biogas reheating, and, a cold water to biogas heat exchanger for biogas cooling.

Cold water is provided by an industrial grade chiller and the heat exchangers are manufactured in 316 Stainless Steel.

The relative humidity of the biogas is set by using the inlet biogas temperature to reheat the cooled exit biogas. If the incoming biogas is not hot enough to provide this heat exchange then hot water is used.
