Nitrogen circuit for filters

Recovery of consumables

A nitrogen recirculation system combined with the BHS Rotary Pressure Filter (type RPF) or BHS indexing belt filter (type BF) provides a very efficient way of storing and using nitrogen (N2). Nitrogen is used for drying and/or blowing out the filter cake. In particular for solvent production facilities, the nitrogen recirculation system is a safe, economical solution that ensures a continuous nitrogen supply and minimizes nitrogen consumption. In addition, the gas recirculation process recovers the solvent used as a washing agent in the filter system, thereby optimizing solvent consumption. Contamination of the washing agent is prevented by using the same solvent as an operating fluid in the gas recirculation system in compliance with industry standards.
