All About Our Silencers

We often hear a lot about industry’s impact on the environment in reference to lowering our carbon footprint. What is not always given as much attention is the issue of noise pollution. For this problem, at Ventx we have the perfect solution with our industrial silencer design. Particularly considering noise levels in the petro-chemical and service industries, the best way to deal with this issue is through a custom design for individual applications.
Innovative Technology
By using advanced computer software, we are able to craft predictive acoustic models within the design phase, so that silencers can be designed prior to the building of the infrastructure. On the other hand, we can also work with existing machinery in order to plan the necessary measures for noise reduction. Typically, we are able to produce gas ejector silencers, direct line silences, vent discharge silencers, and control valve silencers.
Gas Ejector Silencers
A gas ejector silencer uses either hydrocarbon gas or steam, which can be both vented into the atmosphere or in a closed system in order to reduce any noise being produced. This works by attenuating air-born sound waves circulated in a flowing medium. We calculate the ejector noise and flow mixture in order the determine your specific requirements.
Direct Line Silencers
A direct line silencer differs in that it uses absorption rather than pressure variation to reduce any noise created by machinery. Often used with compressors, they can be offered as a complete unit. Alternatively, an acoustic core can be supplied, which would be inserted into existing pipe work.
Vent Discharge and Control Valve Silencers
Finally, vent discharge and control valve silencers are able to lessen the pressure of the gas flow at the same time as absorbing as much sound as possible. This method makes use of both an expansion camber, and an absorptive core. A vent discharge silencer is design to attenuate the noise level to a required sound pressure level, considering the distance from the silencer. They can be used in high pressure vents, steam vents, safety relief valve outlets, system blow downs, purge outlets and so on.
Bespoke Service
At Ventx, we are able to analyse your plans, or assess your current installation by surveying your company. The results will enable us to design and manufacture silencers especially for you, providing a bespoke service that is guaranteed to meet your needs. We use the highest quality materials along with the latest manufacturing techniques in order to craft a silencer that is perfectly suited to your business. Whether you need new silencers for a new development project, or you require silencers for your existing structure, we will be glad to help you.

Reducing the pollution resulting from production processes is an issue in all the heavy industries, and since the pollution takes different forms, so must the measures to reduce it.
Solid waste is usually stored on site until it can be removed by a suitable vehicle.  Special care must be taken when removing hazardous waste, and suitable transport arrangements must be made.  This can mean anything from having the waste containers and the vehicle which transports them correctly labelled with GHS signage, to using a vehicle specifically modified for the task (as in the case of nuclear flasks).  Liquid waste may be similarly removed, or treated on-site and discharged as effluent.
Gaseous waste can be difficult to deal with; storage of waste gas is rarely practical, as it would have to be kept in airtight containers, and with volatile compounds compression may not be an option.  Usually, the only practical solution is to neutralise the gas and release it to the atmosphere.  As you would expect, this practice is very strictly regulated.  Unwanted noise is another form of pollution, and is often a by-product of such gas treatment systems.
If the management of an industrial facility do not take reasonable measures to control the noise pollution produced by its gas venting systems they may leave the company open to prosecution under environmental law.  This is achieved by the use of an acoustic silencer (also known as a muffler) as a part of the gas discharge apparatus.  An industrial silencer works on the same principles as the exhaust silencer fitted to your car.  A system of insulating blocks and acoustic chambers modify the flow of gas to reduce the noise produced as it is released.
Ventx are specialists in the design, manufacture and installation of such industrial acoustic silencer systems.  We use advanced computer software to model the acoustic properties of an existing or planned gas discharge system and predict the characteristics of the sound it will produce.  An effective silencer can then be manufactured accordingly.  Types of silencer include:

  • A direct in-line silencer is the simplest type of industrial noise-abatement device. Industrial compressors are sensitive to pressure variances within the system, so an attached silencer must be designed to maintain the pressure in the pipe.  Therefore, an inline silencer achieves sound modification by use of absorptive baffles.  Different densities of material are available depending on the acoustic profile of the system.  It is usually quite simple to retro-fit an inline silencer into existing pipework.
  • An atmospheric vent discharge industrial silencer uses a diffuser and expansion chamber in conjunction with absorptive material. This reduces the pressure of the gas flow, and therefore the energy which creates the noise.
  • A gas ejector silencer is for use with a steam or combustion exhaust system.
