Process Vacuum is an essential requirement in the Chemical Industry & the Pharmaceutical Industry and is required for following purposes

• Carrying out chemical reactions under vacuum
• Evacuating gases
• Evacuation of Reactors and Vessels.

But at the same time the vacuum equipment working in the Chemical & Pharmaceutical Industry also faces the below challenges….(Read more)

Multiple industrial process require vacuum in the range of 15~40mbar i.e 11~30 Torr and Liquid ring Vacuum Pumps are unable to satisfy them.

In such cases an air ejector can be mounted on the Liquid Ring Vacuum Pump to boost its vacuum. This air ejector uses air from the atmosphere as the energy input and hence is known as Atmospheric Air Ejector.

Dilution Ejectors are essentially liquid eductors that operate on the basis of the jet Venturi principle. Dilution Ejectors utilize the energy in pumped liquid (in most cases the diluting liquid) for their operation. Dilution Ejector operate by first sucking the chemicals through their suction inlet and mixing it with the diluting fluid inside the ejector. (Read more)

Dosing Ejectors are essentially liquid eductors that operate on the basis of the jet Venturi principle. Dosing Ejectors utilize the energy in pumped liquid (in most cases the diluting liquid) for their operation. Dosing Ejector operate by first sucking the chemicals through their suction inlet, mixing it with the pumped liquid inside the ejector and pumping out the mixture from its outlet.(Read more)

Multiple Batch production processes in the Chemical and Pharmaceutical Industries require that the gases dissolved in liquid be separated before beginning of production or at the end of production process.The process of removing gases dissolved or trapped in liquid is known as degassing.An efficient method of degassing liquids is to apply vacuum. When vacuum is applied trapped gases tend to rise from the liquid due to reduced pressure…(Read more)

Gas Micro bubbling is a specialized technique which involves dispersing gas into a liquid in form of very small gas bubbles.

Gas Micro Bubbling is commonly implemented for the following

• To accelerate gas-liquid reactions in the Chemical Industry and Pharmaceutical Industry.
• To promote oxygen dissolution in water in water treatment plants

Analyzing Gas & Liquid samples is a routine requirement of process industry. Gas Samples are frequently drawn to analyze and determine composition of gases. Obtaining samples for pipelines / chambers operating under pressure is easy as the internal pressure forces the gas into the sampling system. But for systems operating at or near atmospheric pressure or under vacuum, the gas sample needs to be pulled out / extracted from the system.

Requirements from the Sampling system….(Read more)

Analyzing Gas & Liquid samples is a routine requirement of process industry. Liquid samples are frequently drawn to study the process progress or to study quality of batch in reactor.Liquid sample need to be pulled out / extracted from reactor / chamber that are operating at or near atmospheric pressure or under vacuum. Liquid samples with high viscosity also requires extraction even if the system is under pressure.

Water Eductors are essentially Liquid jet Vacuum Ejectors that operate on the basis of the jet Venturi principle. Water Eductors utilize the energy in pumped water for their operation and can be put to use to create vacuum conditions at its suction inlet.
A Water Eductor or Liquid jet Vacuum ejector can develop ultimate vacuum upto 30 Torr i.e 40mbar. The water Eductor commonly operates with wide range of motive liquid pressure from 2.5 bar(a) to 7 bar(a). (Read more)

Water Eductors tend to have large suction flows at ambient & low vacuum pressures, this helps the Water Eductor in performing rapid evacuation initially. Combining that with its ability to develop high ultimate vacuum, the Water Eductor can evacuate a vessel / Reactor to high vacuum in less time.

Water Eductors are suited for the process vacuum demands in the Chemical & Pharmaceutical sector because of their inherent characteristics (Read more)
