Vacuum systems are surrounded by the earth’s atmosphere. To create vacuum, it is necessary to pump air out of a system. The internationally accepted unit of vacuum measurement is the Torr.

The Steam Jet Ejector consists of three basic parts: Steam nozzle, Suction Chamber and Diffuser. Steam enters the motive steam nozzle from the steam chest. The nozzle extension is used to establish the position of the motive steam nozzle relative to the diffuser inlet. High pressure motive steam expands across a converging-diverging nozzle and is thus accelerated to a supersonic velocity.

The high velocity motive stream entrain the mixture is accomplished across the diffuser by conversion of velocity to pressure head. This is converted to velocity head in the motive steam nozzle, velocity heads is converted to pressure head in diffuser.

Steam Jet Ejector offer an economical means producing vacuum. It has no any moving parts, simple operation.

Ejector construction:

The ease of Steam Jet Ejector design permits fabrication from any welded material i.e. Carbon Steel, Stainless Steel, Hastelloy, Titanium, Graphite construction.

No of Stages:

Single Stage Ejector creates vacuum from atmospheric to 75 mm Hg A based on provided steam pressure. Higher vacuum more than 1 mm Hg A, may be achieved by multistage ejector. Multi stage ejector require either Barometric or Indirect type condensers. Condenser is require to reduce steam under certain conditions, recover condensate.

Ejector can handle process gases i.e. air, water vapour, SO2, Hexane, Toluene, EG and many other organic & inorganic vapours.

The transfer of heat to and from process fluids is an essential part of most chemical processes. The most commonly used type of heat-transfer equipment is the heat exchanger.
Exchangers in which a process fluid is heated or cooled by a plant service stream are referred to as heaters and coolers. If the process stream is vaporized the exchanger is called a vaporizer if the stream is essentially completely vaporized.
The principal types of heat exchanger used in the chemical process and allied industries are listed below
1. Double-pipe exchanger: the simplest type, used for cooling and heating.
2. Shell and tube exchangers: used for all applications.
3. Plate and frame exchangers (plate heat exchangers): used for heating and cooling.
4. Plate-fin exchangers.
5. Spiral heat exchangers.
6. Air cooled: coolers and condensers.

Pressure vessels are boilers and storage tanks that contain liquids or gases and are designed to operate at pressures above 15 psig. High pressure vessels function under greater than normal amounts of pressure without compromising seals or bursting. Stainless steel pressure vessels are used as storage, mixing, jacketed and reactor tanks in food and beverage processing, pharmaceutical production, and other sanitary applications. Some pressure vessels control the temperature of their contents and are monitored by a series of gauges on the outside of the tank. Others are designed to store volatile substances at high temperatures. 

Pressure vessels are must be adequately maintained and inspected. The American Society of Mechanical Engineers (ASME) rates pressure vessels for safety and standardized usage. ASME pressure vessels are inspected for conformance to industry-wide standards of strength, including higher quality O-ring seals and vacuum closures. Pressure vessel inspection involves ensuring that the pressure vessel is free from ruptured seams or seals and cracks. In some instances, pressure vessel inspection requires dismantling the tank; however, a simple visual inspection or other non-destructive test (NDT) may be adequate to ensure the vessel’s integrity.

Suppliers of pressure vessels are located across the United States and around the world. They differ in terms of certifications, approvals, and industries served. Pressure vessel manufacturers design new tanks using variety of criteria, including the selection of materials to withstand shock, vibration, corrosion, temperature changes, and other environmental conditions. Pressure vessel design must also take into consideration that the materials used to build the vessel are compatible with the materials to be stored in the tank. Often, a pressure vessel manufacturer will adhere to application-specific specifications for the construction of a high pressure vessel or a stainless steel pressure vessel. Pressure vessels that feature custom pressure vessel designs or require NDT pressure vessel inspections are also available.
