ENERGY-EFFICIENT PROCESS FOR PURIFYING VOLATILE COMPOUNDS AND DEGREASING

摘要

Disclosed is an energy-efficient method for degreasing or defluxing comprising a) providing a heated distillation vessel capable of being operated under positive pressure; b) charging with a solvent comprising HCFO 1233zd; c) heating to provide positive pressure so that solvent boils at about 30-100°C; d) distilling using an air-cooled heat exchanger; e) releasing the pressure; f) cooling by channeling through an immersion tank subfloor and/or side; g) collecting the solvent; h) performing degreasing operations; and i) pumping soiled solvent back to the heated distillation vessel. Also disclosed are an energy-efficient method for purifying volatile compounds, and pressurized solvent degreasing system capable of use with HCFO 1233zd.
