Apparatus And Method For Solvent Recovery From Drying Process

Method and apparatus for condensing a majority of the solvent in a process gas stream at low temperatures, e.g., below the freezing point of water, ca. −5° C. The gas stream exiting the condenser step may be further processed in one or more emission control devices, such as a single or multi-step se...

description Method and apparatus for condensing a majority of the solvent in a process gas stream at low temperatures, e.g., below the freezing point of water, ca. −5° C. The gas stream exiting the condenser step may be further processed in one or more emission control devices, such as a single or multi-step series of concentrator devices, such as zeolite concentrator devices. One or more emission control operations can be carried out downstream of the single or multi-step concentrators. The aforementioned condensing process enables the one or more concentrators to operate in a favorable temperature range for removal of 99% or more of VOC, thereby meeting or exceeding strict environmental regulations.
