Where alternate methods are not practical, Demisters are available to separate (demist) product mist from the air being vented from the pipeline as the pig is returned from the Receiving PLR to the Launching PLR.  Demisters provided by Pigging Solutions are designed to both provide a safety reservoir for residual liquid and to filter the liquid mist as the air exits the unit.  The unique design of Pigging Solutions Demisters allow for longer intervals between routine demister maintenance, infrequently attended or remote installation locations, and longer filter media life.  Examples of alternate methods of receiving vented air and mist are blend and storage tanks, totes, and in some instances drains.
