摘要： In a storage system for liquefied gases at least a portion of the compressed gases from the refrigeration system for the storage system are combined with liquefied gases being removed from the storage system to thereby provide heat to liquefied gases being removed from the storage system. This prevents the build up of the light components of the liquefied gases in the storage system and also conserves energy.
摘要翻译：在用于液化气体的存储系统中，用于存储系统的来自制冷系统的压缩气体的至少一部分与从存储系统中移出的液化气体组合，从而向从存储系统移除的液化气体提供热量。这防止了储存系统中的液化气体的轻组分的累积并且还节约了能量。

摘要： Process for re-refining used lubrication oil by contacting the used lube oil in a first extraction zone with a light hydrocarbon solvent, for example, propane, yielding a first extract and raffinate. The solvent is removed from the first extract to recover desired lubrication stock base. The first raffinate is then solvent-extracted, using the same solvent to produce a second extract and raffinate. The solvent is then removed from this second extract to yield an oil which can be further refined for separation of valuable constituents or burned as fuel oil. The second raffinate is flashed to remove any remaining solvent and leave an easily discardable solid residue.
摘要翻译：通过使第一提取区中使用的润滑油与轻烃溶剂例如丙烷接触来再次精炼所使用的润滑油的方法，产生第一提取物和残液。从第一提取物中除去溶剂以回收所需的润滑原料。然后使用相同的溶剂对第一萃余液进行溶剂萃取以产生第二提取物和萃余液。然后从该第二提取物中除去溶剂，得到油，其可进一步精制以分离有价值的组分或作为燃料油燃烧。闪蒸第二个残液以除去任何剩余的溶剂，并留下容易丢弃的固体残留物。

摘要： Deposition of ammonium chloride from gaseous streams is prevented by maintaining the temperature of the gaseous stream above the deposition temperature for ammonium chloride at operating pressure. The invention is particularly useful in hydrocarbon hydrogen treating processes in which hydrogen recycle streams containing ammonium chloride or ammonium chloride-forming constituents must be recompressed before recycle to the hydrogen treating process.

摘要： Heavy hydrocarbon materials containing asphalt are separated into three different fractions according to chemical composition, namely, a paraffin-waxy fraction, a resin fraction, and an asphaltene-solids fraction, by a process comprising two-stage solvent treatment at different solvent-to-feed ratios and different temperatures. In another embodiment, a fourth product comprising an asphalt fraction can be produced by blending a portion of the resin fraction with a portion of the raffinate obtained from the first solvent extraction fraction stage.
