Making chemical processes possible with vacuum technology

Chemical compounds are a part of our everyday lives in small but vital ways. They make useful packaging materials, they help us grow food, they are in our medicines and cosmetics, they help us to make the world greener and our lives more sustainable. From smart phones to vehicles, from foam mattresses to clothing and footwear, from kitchen to farms, we are living in a world defined by chemicals. 

Chemicals in our daily life

Chemical processes are not always easy to handle, with many challenges where vacuum lends a helping hand. All successful chemical manufacturers understand the crucial role of vacuum for chemical processing. These challenging applications require superior vacuum performance, dependable energy efficiency, with a lower cost of ownership and environmentally friendly concept functioning, with the added guarantee of reliability and safe operations. 

Which vacuum pump is right for your application?

The chemical processing industry is diverse and covers sectors such as oil and gas, petrochemical, pharmaceuticals, specialty and fine chemical, biobased chemicals, flavors and fragrances, vapour recovery and more. With rapid advances in technology, chemical processing industry place increasingly challenging demands on vacuum systems. As a world leader in vacuum solutions and innovator in vacuum pump design and manufacturing, Edwards offers a comprehensive range of vacuum pumps that cater to a variety of applications, which can navigate the complexities of the process industry with confidence and empower our customers to optimise production, minimise downtime, and maximise efficiency with the right pump technology and tailored solutions. 

Vacuum solutions
  • Edwards dry vacuum pumps are capable of handling increasingly complex chemicals, solvents in a reliable and safe way through precise temperature and pressure control, while ensuring reduction of environmental pollution at a low cost of ownership.
  • Edwards liquid ring pumps offer a very wide capacity range and significant advantages when pumping wet gases and vapors or when used for applications requiring special construction materials for corrosion resistance.
  • Edwards rotary vane pumps are specially designed to handle less challenging processes and are suitable for flammable atmospheres. They are renowned for simple, quiet operation and achieving high ultimate vacuum.
  • When coupled with our wide range of vacuum pumps, Edwards mechanical boosters increase pumping speed at working pressures, significantly improving process throughput and reducing the pump downtime.
  • Edwards has been instrumental in the development of many types of ejectors, both with steam or gas as the motive fluid, either as stand-alone or as hybrid systems combined with liquid ring pumps to handle high vapour loads without the risk of cavitation.
  • Edwards oil vapour booster pumps are field proven in various industries including in chemical industry for short path distillation to achieve the low operating pressure. They benefit from their inherent capacity at low pressure, reliability, ease of use and maintenance.

Why choose Edwards vacuum solutions?

As industry experts in vacuum technology and decades of application expertise. We don’t just provide product for your application needs but rather focus on creating all-round dependable vacuum solutions and support and enhance and empower your processes and operational goals. 

Commitment to quality production

Vacuum is used in a wide range of chemical processing industry applications, including but not limited to distillation, concentration, evaporation, drying, filtering, reactions, polymerisation, solvent recovery, crystallisation, desorption, deodorisation, hydrogenation, sterilisation, etc. A vacuum system can affect every aspect of a process, such as utility consumption, processing times, quality of product, safety and environmental impact. Benefits of vacuum enabling chemical processing industry including but not limited to:

  • Reduced energy consumption
  • Reduced risk of heat damage to sensitive products
  • Enhanced product quality through impurity removal
  • Safer operating atmospheres through oxygen exclusion
  • Increased yield by shifting reaction equilibrium.

Safe operations in hazardous environments

During a chemical processing process, vacuum pumps are often used to pump potentially flammable or explosive gases and vapours. Mishandling these applications/substances can result in big safety risk. Edwards can offer a wide range of products which are designed to handle flammable atmosphere, or to operate in an explosive atmosphere, without causing an explosion or fire hazard. These products are certified for use in and with explosive atmospheres certified for ATEX, adhering to relevant American and other applicable global standards.

For regional markets, suitable electrical components like valves, motors for hazardous location to suit the customer requirements can be chosen and combined with the Edwards chemical pump range to achieve compliance with the country’s explosion proof legislation.
