DESIGNING STEAM JET VACUUM SYSTEMS
www.graham-mfg.comVacuum piping.Paragraph 6.3 of the Heat Exchange Institute’s Standards for Steam Jet Vacuum Systems (4th ed.) details the pro-cedure for calculating pressure drop in vacuum systems. In general, the diameter of the piping between the process and the ejector system must be at least as large as the suction connection in the first-stage ejector.
AP-42, CH 6.6.2: Poly(ethylene Terephthalate)
www3.epa.govThe vacuum conditions in the prepolymerization and polymerization reactors are created by means of multistage steam jet ejector (venturi) systems. The vacuum system typically is composed of a series of steam jets, with condensers on the discharge side of the steam jet to cool the jets and to condense the steam. The

tuttnauer.comWATER RING VACUUM PUMP The vacuum pump effectively removes air from the chamber. The pump is mounted on vibration absorbers to minimize vibration. During vacuum action the flow path of the media is through the condenser (heat exchanger) and the vacuum pump/ejector to drain. This protects the vacuum system from excessive temperatures.
Proper Piping for Vacuum Systems - graham-mfg.com
www.graham-mfg.comSuction lift is a function of vacuum systems that can be used to advantage in piping (Figure 2). For example, it can enhance a pumping system by reducing the load on an existing motor. Imagine, for instance, pumping a liquid from one level up 80 ft to a vessel operating under vacuum. The vacuum or suction lift

For vacuum, barometric leg condenser, vacuum pump and steam ejector are generally used. The evaporators may employ natural or forced circulation of the product. In natural circulation units, circulation of the liquid

www.inscogroup.comVacuum principle Here, an ejector pump is used to create a vacuum in the tank. This causes the tank water to start boiling because of the low temperature, which in turn removes air from the water. This principle is normally used for steam turbine applications.
