    • Contaminated glycol is refined by vacuum distillation. Specifically the evaporator is heated to a temperature below the degradation temperature of the glycol. The vacuum is used to bring the flashpoint down sufficiently so that glycol evaporates or flashes at that temperature. The glycol is condensed and filtered through activated granular carbon. The principal use of refining the glycol is to refine the triethylene glycol used in natural gas dehydration plants. For such purposes the equipment is mounted upon a trailer to be taken to the plant for cleaning glycol. In such instance, in addition to refining the glycol, a cleaning agent (which contains a degreaser) is added to the refined glycol. The glycol is refined while the natural gas dehydration plant is in normal operation and therefore it is not necessary to stop the natural gas dehydration plant for refining the glycol used therein. In addition, by the addition of the cleaning agent, the dehydrating plant equipment may be cleansed of hazardous waste. The hazardous waste will be separated and concentrated in the distillation. Therefore, the transportation of the hazardous waste to a disposal location is simplified.
    • 污染的二醇通过真空蒸馏精制。 具体地说,将蒸发器加热到低于二醇降解温度的温度。 使用真空使闪点足够下降,使得二醇在该温度下蒸发或闪蒸。 将二醇冷凝并通过活性颗粒碳过滤。 精炼二醇的主要用途是精炼天然气脱水设备中使用的三甘醇。 为了这样的目的,将设备安装在拖车上以被带到工厂以清洁二醇。 在这种情况下,除了精制二醇之外,将还原剂(其含有脱脂剂)加入到精制二醇中。 在天然气脱水装置正常运行的同时,乙二醇精制,因此不需要停止天然气脱水装置来精制其中使用的二醇。 此外,通过添加清洁剂,可以将脱水设备设备清洗成危险废物。 危险废物将在蒸馏中分离和浓缩。 因此,将危险废物运往处置场所简化。

    • The object of the invention is to provide a solvent distillation apparatus capable of preparing a highly pure anoxic, dehydrated solvent. A distilling flask is connected to a vacuum double-barrel fractionating column by a glass flange. The upper end of the fractionating column is connected to a middle portion of a reflux condenser. The upper end of the reflux condenser is provided with an outlet for a purge gas, and the lower end thereof is connected to a condensate reservoir. The base of the condensate reservoir is connected to the fractionating column near a lower end thereof via a Young cock, and also connected to a collecting flask via a Young cock and a glass flange. An immersion tube is used to blow an inactive gas into a base portion of the condensate reservoir. The fractionating column, the reflux condenser and the condensate reservoir are integrated as one body.
