Dehumidifying heat exchanger

shell and tubegas/liquidfor biogas treatment

Especially in the biogas sector, the biogas produced contains about 30% humidity, o.r.,water vapour, depending on the temperature. Before entering gas engine, this humidity must be filtered from the biogas. The simplest way to eliminate this humidity is to cool biogas. When biogas is cooled to approximately 10°C, the moisture content of the biogas decreases to approximately 1%. For this process, shell and tube heat exchangers are often preferred for their low pressure loss. In the case of biogas applications, biogas is transported by pipeline, while cooling water is transported by the shell side.
