Vacuum pumps for petrochemicals

In petrochemicals, vacuum pumps convey flammable gases and vapours ā€“ in aromatics extraction, in BTX, LAB, styrene and MMA plants and in adhesive production ā€“ and, according to Edwards, they must do so without contamination. For the industry, Atlas Copco names liquid ring vacuum pumps and ejector systems; this page is part of the Chemicals industry. Below you can see which series the manufacturers themselves name for these tasks ā€“ 98 models from 2 manufacturers.

In short

Petrochemicals: vacuum pumps ā€“ the key facts

  • Flammable substancesFor the petrochemical industry, Edwards names the contamination-free pumping of flammable substances and, for this, the GXS, EDS and EH series.
  • Named processesAromatics extraction, BTX, LAB, styrene, adhesives and MMA ā€“ these are the processes Edwards names for petrochemicals.
  • Liquid ringAtlas Copco names petrochemicals for the AWS, AWD and AWL liquid ring vacuum pumps and for ejector systems.
  • Up to 8 bar(a)For gas compression (CO2, Cl2, H2/C2H2) and VCM recovery, Edwards names liquid ring compressors up to 8 bar(a).

Applications

Petrochemicals: what vacuum pumps are used for

For each application: what the vacuum does and which series the manufacturers name for it. The information comes from the manufacturersā€™ own pages.

Aromatics extraction and BTX

Edwards names aromatics extraction and BTX for the petrochemical industry; according to Edwards, the pumps must convey flammable substances without contamination. GXS, EDS and EH are named, as well as CXS, CDX and EDP.

  • EdwardsGXS, EDS, EH Edwards also names CXS, CDX and EDP

Styrene, MMA, LAB and adhesives

For styrene, MMA, LAB and adhesives, too, Edwards names the same series ā€“ GXS, EDS, EH ā€“ and the same aim: pumping flammable substances without contamination. Edwards gives no further details on pressure or pumping speed on its industry page.

Liquid ring vacuum pumps and ejector systems

Atlas Copco names petrochemicals for its AWS, AWD and AWL liquid ring vacuum pumps and for steam jet ejector systems, without describing the task in detail.

Selection

Petrochemicals: choosing a vacuum pump

What the manufacturers highlight for use in this industry.

Flammable media

As a requirement, Edwards names the contamination-free pumping of flammable substances ā€“ for all the processes named, from BTX to MMA. GXS, EDS and EH are named for this; the industry page gives no information on explosion protection.

Liquid ring or dry pump

In petrochemicals, Atlas Copco relies on liquid ring vacuum pumps (AWS, AWD, AWL) and ejector systems, while Edwards names GXS, EDS and EH. Both routes are in our range.

Compressing instead of evacuating

Where gases are not extracted but compressed ā€“ CO2, Cl2, H2/C2H2, VCM recovery ā€“, Edwards names liquid ring compressors up to 8 bar(a).
