摘要： Sorbents used for drying organic liquid process streams can be regenerated by passing an organic liquid carrier solvent such as n-octanol therethrough at a temperature sufficient to dissolve water trapped in the sorbent, thus regenerating it, and subsequently cooling the organic liquid carrier solvent/water solution such that it separates out allowing recycle of the organic liquid. This method of sorbent regeneration allows the use of low grade heat for regeneration thus improving the viability of sorbent drying plant.

摘要： A process providing continuous or quasi-continuous sorption uses at least three fixed bed sorbent zones connectable in series by pipes, for the passage of a liquid phase containing a component to be sorbed. The approach of saturation of one or more of the zones is detected, e.g., using temperature sensors, and regeneration of the saturated zone or zones is initiated using hot gas. Compared to conventional sorption processes, energy savings, especially as regards energy consumed in blowing the hot gas through the fixed bed zone, are obtainable.

摘要： In the froth flotation of coal, especially coking coal, improved results are observed when using as a collector an oil distillate cut within the range 80.degree. to 250.degree. C., containing less than 20% by weight of naphthenes, less than 20% by weight of aromatic content and more than 60% by weight of n-alkanes and branched-alkanes. Preferably, the collector is used with a polyglycol ether "frother".

摘要： This invention relates to froth flotation of coal.According to the invention a predominantly paraffinic residual oil having a cut point of at least 190.degree. C. at atmospheric pressure is used as a "collector" for the froth flotation of minerals. A preferred oil is a coal spray oil used in coke oven technology. The "collector" is for use with a "frother" such as a polyglycol ether.
