Abstract
An emission control system for a fluid composition comprised of volatile constituents used to clean a hollow fiber filter or capillary flow dialyzer including a housing having a chamber for receiving the dialyzer, a control system is used for establishing a desired environment in the chamber, the dialyzer and the fibers, a separator operatively associated with the chamber for separating gas and liquid components of the fluid composition, a stripper connected to the separator for fractionating lower boiling point volatiles from the gas to return the higher boiling point volatiles to the fluid phase and yield a stripped or solvent humidified gas and a delivery system for routing the stripped gas to the chamber dialyzer and fibers as a drying agent.
