Definitions

  • a gas cooling and drying plant 6 Following the condenser 4 and cooler 5 is a gas cooling and drying plant 6.
  • the gas leaving the cooler and dryer 6, usually will be at a temperature in the range of O-30C, with a humidity corresponding to a dew point in that range.
  • preliminary adsorber 7, and a second preliminary adsorber 7' which is used as needed.
  • the main adsorber 8 Following directly on preliminary adsorber 7 is the main adsorber 8.
  • the main adsorber can include one or more adsorption columns.
  • vacuum pumps 9 and 9 by which the treated gas is led to an exhaust air and exhaust gas chimney 10.
