Introduction
LRP200000201 Issue A
separate the process gasses and remaining vapours from the used sealing liquid. The process gases and remaining
vapours are exhausted through the outlet connection of the separator tank and into an exhaust extraction system,
while the recovered sealing liquid is recycled back to the liquid ring pump through a heat exchanger. The heat
exchanger removes the heat of compression and any latent heat of vaporisation in order to maintain a constant
temperature to the liquid ring pump. The excess sealing liquid goes to a safe drain whilst any evaporative losses are
made up with fresh sealing liquid.
