Steam Jet Ejector Vacuum Systems

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.

Steam jet ejector vacuum systems.

Produced exclusively in the usa and maintained across the globe jet vac technologies has revolutionized the vacuum industry processes by delivering safe cost effective and durable vacuum. For over 65 years jet vac technologies has been providing customers with custom vacuum solutions to help solve and provide efficient reliable process vacuum systems. An ejector performance curve gives the expected suction pressure as a function of water vapor equivalent loading fig. Jet vacuum systems private limited.

11 7 2 steam jet ejectors. They are applied in processes such as crystallization deaeration drying cooling high vacuum distillation and deodorization. Virtually maintenance free with no moving. In an ejector a working fluid liquid or gaseous flows through a jet nozzle into a tube that first narrows and then expands in cross sectional area.

Greater which is the case with cvdu ejector 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. Phair in geothermal power generation 2016. In a steam jet ejector the motive fluid is a jet of high pressure and low velocity compressible steam which exists from the nozzle at the designed suction pressure and super sonic velocity thus entraining the vapour in to the suction chamber.

Compared with other mechanical compressors steam jet ejectors offer the benefits of no moving parts and low cost. Standards for steam jet vacuum systems 4th ed details the pro cedure for calculating pressure drop in vacuum systems. Steam jet ejectors the largest vacuum producing devices available are used in the most demanding of applications. Heat exchange institute standards for steam jet ejectors describes the method to convert the mixture air water vapor and various hydrocarbons to a water vapor.

A vacuum ejector or simply ejector is a type of vacuum pump which produces vacuum by means of the venturi effect. Ejector based systems are particularly appropriate as primary vacuum producers particularly where motive steam is almost always available.
