METHOD AND PLANT FOR RECOVERING WORKING FLUID

摘要

The invention relates to a method for recovering working fluid, in particular from a leakage gas flow occurring when heat is being recovered from the working fluid, the flow containing low-boiling liquid and/or gaseous components of the working fluid. The invention also relates to a plant for carrying out said method. According to the invention, in order to recover the working fluid, a liquefied gas is evaporated as refrigerant and the leakage gas flow is guided first through a pre-condenser (4) in counter-flow to the refrigerant at higher temperature and then through a main condenser (3) at lower temperature in order to condense the working fluid out of the leakage gas flow.
