Steam Jet Vacuum Systems Overview

Steam Jet Ejectors are used in the chemical, petrochemical, pulp and paper, food, power, steel and allied industries in connection with such operations as filtration, distillation and evaporation, absorption, mixing, vacuum packaging, freeze drying, flash cooling, deaerating, dehydrating and degassing to name just a few. They will handle both condensable and non-condensable gases and vapors as well as mixtures of the two. Small amounts of solids or liquids will not adversely affect performance. 

Steam Jet Vacuum Systems Types

Single-Stage Steam Jet Ejector

(handle both condensable and non-condensable gases and vapors as well as mixtures of the two where small amounts of solids or liquids will not cause operating problems)

Multi-Stage Steam Jet Ejector

(staging of ejectors becomes necessary for economical operation as the absolute suction pressure decreases)

Multi-Stage Vacuum System for Power Applications

(the extraction of a mixture of water vapor and air from an air cooled condenser in a power plant)


General Applications:

Filtration; Distillation; Impregnation; Absorption; Drying; Degassing; Dehydration; Evacuating; Cooking; Evaporating; Vacuum transfer; Chilling; Removing condensate under vacuum; Exhausting air from vacuum pans and evaporators; Priming centrifugal pumps; Handle air or other gases at suction pressures as low as three microns hg. abs.; Decarbonating brewery water; Creating chemical process vacuums; Water treating by degasifying; Used in degassing molten steel; Perfume concentration; Distillation; Vacuum packaging; Freeze drying; Flash cooling; Typical Five Stage Steam Jet Ejector; Steel degassing; Chemical distillation; Distillation and evaporation; Air removal from main turbine condensers; Vessel evacuation; Exhausting non-condensable load; Geothermal applications
