Alternative form of distilment

US standard spelling of distil.

(physics, chemistry) a separation method in which a nonwetting, microporous membrane is used with a liquid feed phase on one side of the membrane and a condensing, permeate phase on the other

(chemistry) The heating of a material, such as coal or wood, in an inert atmosphere, at a high temperature such as to cause decomposition; the principal products include oils and tars from which many useful organic compounds may be obtained; town gas and coke were obtained in this way.

A substance used to force a distillate in a distillation, as it has a boiling point more than that of the substance to be extracted and less than that of the impurities. It is rarely used but mostly with fractional distillation when column packing is used. As it vaporises it heats the column packing and causes the trapped fluid to rise over.

The concentration of volatile pollutants, generated in the temperate zones, in the polar regions

plural of steam distillation

plural of vacuum distillation

(chemistry) Distillation under reduced pressure, and thus at a reduced temperature with less risk of thermal degradation

plural of membrane distillation
