Bronkhorst UK is leader in Mass Flow Meter / Mass Flow Controller technology for gases and liquids, Pressure Controllers and Evaporation Systems.
Generating vapour is a perfect example of how technology development in one area can benefit multiple industries. By combining the accuracy and digital performance of modern mass flow metering and control technology, alongside temperature control, you can control the properties of vapour as never before.
Vapour production has always been a necessary, yet complex and expensive process. There have been multiple methods employed to achieve the dispersion of liquid into a gas phase. The variety of methods used is a reflection of the bespoke approach taken by many to compensate for the lack of awareness of a commercially viable solution.
There are many industries that need, or would benefit from vapour generation to achieve their end goal, we have been talking to biomedical researches, technical fabric manufacturers, glass coating companies, catalysis research & development, graphene research & development and bulk food packaging machine manufacturers.
As always there are a few common themes amongst each of the people that we speak to. In application development the drive is always to increase or decrease something, it could be: cost, waste, yield or raw materials. Almost anything associated with an application will either have an increase or decrease requirement.
Multiple factors can be improved by installing a Bronkhorst Controlled Evaporating Mixing system (CEM) or Vapour Delivery Module (VDM) in your installation, these include:
Vapour is generated through the addition of a liquid into a gaseous stream, usually under temperature. We add control to each of the inputs, thereby acquiring control of the output. If we take the first example from the list at the beginning of this blog, Dew-point generation, then we can see;
By removing those sources of variation from the input, combining liquid flow control with a Coriolis mass flow meter (MFM) and gas flow control with thermal bypass mass flow controller (MFC) with a temperature controlled flow path you can predict the conditions of the resultant vapour more accurately. Once an output has been achieved with a known input combination, it can be replicated repeatably.
For example, in the picture below we know that the input conditions entered will achieve the desired process conditions, that level of control is not available in the other process.
With direct control of the liquid and gas flows into a temperature controlled flow path it is easy to change the input conditions and predict consistent process conditions. The Coriolis liquid mass flow meter and thermal bypass gas flow controller are directly linked to a 3-way mixing valve on top of a temperature controlled flow path. By passing the liquid and gas through the valve orifice the combined flow is aerosolized before being heated and this ensures complete vaporisation of the liquid in the gas stream.
Taking this a stage further, if you have a specific composition in mind then check out our online free to use database called Fluidat, go to www.fluidat.com register and you can check out yourself what is possible.
Looking at the 6 old ways and 1 new, the innovation and thought that has gone into the original and still used old methods of vapour generation is clear.
However the beauty of society is that we can learn from one another, another technology is available.
