Effective way - the energy for refining and degreasing volatile compounds

摘要

a) providing a heated distillation vessel can be operated under positive pressure; b) filling a solvent containing HCFO 1233zd; c) the solvent is hayeoseo heating to boiling at about 30 to 100 ℃ provide a positive pressure; d) the air-distillation step of using a cooling heat exchanger; e) the step of releasing the pressure; f) step of cooling by channeling through the immersion tank sub-floor and / or side; g) collecting the solvent; h) performing a degreasing operation; And i) the energy for a step for pumping back into the heating vessel for the contaminated solvent was evaporated, skimmed or di fluxing-effective method is disclosed. Energy for purifying a volatile compound-pressurized solvent degreasing system for use with an efficient method and HCFO 1233zd is also disclosed.;
