Easy to handle corrosive and slugging liquids.

The initial cost is very less and no spares required.

Hence space requirement will be very low.

Ejectors can be installed indoors or outdoors without restriction.

Hence low maintenance cost when compared with other peer equipment.

No moving parts, no lubrication, no vibration.

Ejectors can be operated with many different motive fluids: steam, air, organic vapour and other gases.

Since any misalignment will adversely affect the performance of ejector.

Hence it very important to provide a drain valve installed at low points can be either manual or automatic float operated valves.ДЄnother important thing to check during ejector installation is external loads(Piping load) act on the ejectors. Since any condensed or solid particles may reduce the throughput capacity of the ejectors. However, it is very important to provide a provision to remove the condensate or solid particles from the entrained gases of an ejector. Ejector InstallationД®jectors may be installed at any orientation. if greater compression is required, two or more ejectors will be arranged in series. By the required capacity is very high then two or three ejectors are working in parallel. The capacity of an ejector is determined by its dimensions. Normally the discharge pressure will be 10 to 15 times of the suction pressure Capacity of Ejectors Thereby the mixture gained higher pressure send to the atmosphere or some closed system. Then the mixture travels through the diffuser вЂњEвЂќ, its velocity energy is converted into pressure energy.

The velocity of the fluid at the mixing chamber is approximately 600 to 900 meters per second. When the suction fluid starts to mix with the motive fluid in the mixing chamber. Due to this suction fluid вЂњCвЂќ (air or gas) from the connected vessel moves toward the mixing chamber вЂњDвЂќ. The motive fluid will create a vacuum in the mixing chamber refer to to the pressure curve where the pressure is decreased and velocity is increased.

Refer to the below figure, a high pressure motivating fluid enters at вЂњAвЂќ and expands through the converging-diverging nozzle to вЂњBвЂќ. The suction line of the ejector is connected to the vessel which is to the kept under low pressure. In mixed fluid enter the diverging portion of the ejector where its velocity energy is converted into pressure energy. Due to the low-pressure zone, the suction fluid will start to move toward it and mix with motive fluid in the mixing chamber. Due to the pressure drop of the motive fluid, it will create a low-pressure zone before the mixing chamber. The operating principle of the ejector is the pressure energy in the motive fluid is converted to velocity energy by an adiabatic expansion in the Converging/Diverging Nozzle. The operating principle of the ejector is the pressure energy in the motive fluid is converted to velocity energy by an adiabatic expansion in the Converging/Diverging Hence it is relatively low-cost and easy to operate and maintenance-free equipment. The major difference between the ejector and vacuum pump or compressor is it had no moving parts. An ejector is similar to a vacuum pump or compressor. An ejector is a device used to suck the gas or vapour from the desired vessel or system.
