Reflux - Wikipedia

A mixture of reactants and solvent is placed in a suitable vessel, such as a round bottom flask.This vessel is connected to a water-cooled Liebig or Vigreux condenser, which is typically open to the atmosphere at the top.The reaction vessel is heated in order to boil the reaction mixture; vapours produced from the mixture are condensed by the condenser, and return to the vessel through gravity.

Use of Liquid Ring Vacuum Pump in Power Plant Industry

The pump is mounted at exhaust of the condenser. These pumps maintain a vacuum at the condenser side preventing turbine back pressure (condenser air hogging), remove any non condensable air and maintain a slight vacuum (holding). Single and double stage ring pump can be used depending on the plant size. Since the pump uses water, most water .
