    • 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.
    • 公开了一种用于脱脂或去焊剂的节能方法,其包括a)提供能够在正压下操作的加热蒸馏容器; b)用包含HCFO 1233zd的溶剂充电; c)加热以提供正压,使溶剂在约30-100℃沸腾; d)使用空气冷却换热器蒸馏; e)释放压力; f)通过通过浸没槽底层地板和/或侧面进行冷却; g)收集溶剂; h)进行脱脂操作; 和i)将污染的溶剂泵送回加热的蒸馏容器。 还公开了一种用于净化挥发性化合物的节能方法,以及能够与HCFO 1233zd一起使用的加压溶剂脱脂系统。
