The vacuum distillation unit shown below consists of a distillation column, condensing distillate, and reboiler. Vacuum pumps and vacuum regulators are added to distillation columns to maintain the column at a vacuum. Many species can be distilled at much more economical temperatures with the use of these vacuum distillation columns.

Steam Pressure Reduction: Opportunities and Issues

a constant output of 38,500 lb/hr. As tested, the boiler stack temperature varies linearly with steam pressure. A savings of 0.4% to 0.8% of the fuel input can be expected from lower stack temperature. Boiler Radiation and Convection Loss. For watertube boilers, radiation loss can be estimated using the American Boiler Manufacturers Association
