Abstract
Process vapors are condensed and recovered by bubbling a vapor up through a bed of inert particulate material, immersed in a liquid. The particulate material is supported on a perforated member in a container, with a condensate collecting chamber at the bottom. The condensate collects below the liquid. The vapor is fed through a diffuser positioned below the bed and condensate can be recycled to backwash the bed. The liquid temperature is controlled, together with the liquid level, liquid pH and also vapor flow rate.
