In order to feed endothermic engines, the biogas from cogeneration plants must undergo dehumidification treatment. Otherwise, if it still contained high levels of moisture, it could irreparably damage the expensive power generation units.
We have been supplying shell and tube heat exchangers for these applications for years, with a range from a few tens of cubic metres per hour up to about 1500 m3/h. Depending on the pollutants in the biogas, either a full stainless steel or mixed iron-stainless steel construction can be selected.
