Pressure vessel — Vertical pressure vessels installed in a structure A pressure vessel is a closed container designed to hold gases or liquids at a pressure substantially different from the ambient pressure. The pressure differential is dangerous and many fatal… … Wikipedia
vacuum distillation — distillation under reduced pressure to avoid the decomposition which might occur at atmospheric pressure … Medical dictionary
Vacuum distillation — Distillation under reduced pressure (less the atmospheric) which lowers the boiling temperature of the liquid being distilled. This technique with its relatively low temperatures prevents cracking or decomposition of the charge stock. U.S.… … Energy terms
Vacuum distillation — At atmospheric pressure, dimethyl sulfoxide boils at 189°C. Under a vacuum, it distills off into the connected receiver at only 70°C. Vacuum distillation is a method of distillation whereby the pressure above the liquid mixture to be distilled is … Wikipedia
