Application

Vacuum pumps for gas and vapour recovery

In gas and vapour recovery, the vacuum pump draws vapours and gases out of storage tanks, lines or processes instead of flaring them or letting them escape; they are condensed, compressed or returned in a circuit – from flare gas and helium to the surplus hydrogen of a fuel cell. Below you can see how the application works, what vacuum the manufacturers name and which of their series are intended for it – 318 models from 5 manufacturers.

In short

Gas and vapour recovery: the key facts

  • Vapours from tanksBusch describes the extraction of vapours from storage tanks (COBRA, DOLPHIN, R5); Edwards names pumps that draw gases out of lines and tanks (LR compressors, chemical dry pumps, nES Ex).
  • Flare gasAccording to Busch, waste gases and flare gases are extracted and compressed (DOLPHIN incl. LN compressor, MINK); Edwards names the use of the hydrocarbons as fuel with LR compressors.
  • HydrogenAccording to Busch, with MINK MH 0018 A, 20–70 % of the H₂ feed goes back into the stack of the fuel cell as surplus hydrogen.
  • HeliumFor helium recovery, cryostats and superconducting magnets, Leybold names ECODRY 65 He plus with a leak rate below 5×10⁻⁸ mbar·l/s for closed circuits of permanent gases; for helium-3 and helium-4, Edwards lists XDS, nXRi, EXS and nXQ55i.

Operating principle

How it works: Gas and vapour recovery

The drawing shows the basic principle in section. The systems and pumps of the individual manufacturers differ in detail.

  1. ExtractionThe pump draws vapours and gases out of tanks and lines (Busch, Edwards) or takes up the surplus hydrogen of the stack (Busch).
  2. CondensingCondensable components are cooled and separated as liquid; for gas circulation, Becker names heat exchangers that cool the gas. According to Busch, flare gas is compressed – DOLPHIN with LN compressor.
  3. ReturningThe gas is used as fuel (Edwards), goes back into the stack (Busch) or remains in a closed circuit (Leybold, Becker).

Vacuum and sizing

Gas and vapour recovery: how much vacuum is needed

What the manufacturers say about pressure, pumping speed and sizing.

Which vacuum

For ECODRY 65 He plus, Leybold gives a leak rate below 5×10⁻⁸ mbar·l/s – important because helium must not be lost in closed circuits; for gas circulation, Becker names gas-tight blowers with KF flanges.

Which pumping speed

For helium return, Edwards names nXQ55i with up to 52 m³/h. For hydrogen recirculation, Busch names 20–70 % of the H₂ feed that goes back into the stack.

What determines the sizing

The gas: hydrocarbons from tanks and flares (Busch, Edwards), helium in cryostats (Leybold, Edwards), hydrogen in fuel cells (Busch) or expensive gases that, according to Becker, are to remain in the circuit without loss – and whether the gas is only extracted or also compressed (Busch: DOLPHIN with LN compressor).

What the manufacturers point out

Becker assigns gas circulation to the blowers (compressors) and names heat exchangers for cooling; for vapour recovery, Edwards names the nES Ex alongside LR compressors and chemical dry pumps; Atlas Copco names liquid ring systems for vapour recovery and DWS VSD+ for gas recovery and circulation without a description.

Industries

Gas and vapour recovery: where the manufacturers name it

The manufacturers list these uses on their own pages.

Oil and gas

Busch describes the extraction of vapours from storage tanks (COBRA, DOLPHIN, R5) and flare gas recovery, in which waste gas and flare gas are extracted and compressed (DOLPHIN incl. LN compressor, MINK); Edwards names pumps that draw gases out of lines and tanks (LR compressors, chemical dry pumps, nES Ex), and the use of the hydrocarbons from flare gas as fuel.

Industry page: Oil and gas →

Hydrogen and fuel cells

In the fuel cell, Busch describes hydrogen recirculation with MINK MH 0018 A: 20–70 % of the H₂ feed goes back into the stack as surplus hydrogen.

Industry page: Hydrogen and fuel cells →

Environmental and wastewater

Busch and Pfeiffer Vacuum also assign the application to environmental technology; for exhaust gas recovery, Busch names MINK, for circulation DOLPHIN and SAMOS, and Pfeiffer Vacuum lists both in its product finder without a description.

Mining

Busch and Pfeiffer Vacuum also assign the application to mining: for exhaust gas recovery, Busch names MINK, for circulation DOLPHIN and SAMOS, and Pfeiffer Vacuum lists both in its product finder.

Industry page: Mining →

Mechanical engineering and manufacturing

Becker describes gas circulation with gas-tight blowers (SV, VASF, VARIAIR RV, VATP, with KF flanges) that convey expensive gases in a circuit without loss while heat exchangers provide cooling; gas circulation in CO₂ lasers is also named.

Industry page: Mechanical engineering and manufacturing →

Packaging

In dry secondary packaging, Becker names the circulation of oxygen-reduced air for a longer shelf life of food.

Frequently asked questions

Gas and vapour recovery: frequently asked questions

How does vapour recovery with vacuum pumps work?

The vacuum pump draws off the vapours that form in storage tanks and lines – Busch describes extraction from storage tanks, Edwards pumps that draw gases out of lines and tanks. The vapours are cooled and condensed, or compressed and, according to Edwards, used as fuel.

Which vacuum pump for vapour recovery from storage tanks?

Busch names COBRA, DOLPHIN and R5, Edwards LR compressors, chemical dry pumps and the explosion-proof nES Ex, Atlas Copco liquid ring systems. For exhaust gas recovery, Busch names MINK, and Pfeiffer Vacuum lists it in its product finder.

Which vacuum pump for flare gas recovery?

Busch names DOLPHIN – also with an LN compressor – and MINK: waste gas and flare gas are extracted and compressed. Edwards names LR compressors, with which the hydrocarbons are used as fuel instead of being flared.

How does hydrogen recirculation in fuel cells work?

The stack does not use all the hydrogen supplied; the surplus is extracted and fed back in. For this, Busch names MINK MH 0018 A and 20–70 % of the H₂ feed that goes back into the stack.

Which vacuum pump for helium recovery?

Leybold names ECODRY 65 He plus for helium recovery, cryostats, dilution refrigeration and superconducting magnets – closed circuits of permanent gases with a leak rate below 5×10⁻⁸ mbar·l/s. For helium-3 and helium-4, Edwards lists XDS, nXRi, EXS and nXQ55i, the nXQ55i with up to 52 m³/h of helium.

What is gas circulation and which blowers are suitable for it?

In gas circulation, a gas is conveyed in a closed circuit, for example in CO₂ lasers or as oxygen-reduced air in packaging. For this, Becker names gas-tight side channel and radial blowers (SV, VASF, VARIAIR RV, VATP) with KF flanges that convey expensive gases without loss, and heat exchangers that cool the gas; for circulation, Busch names DOLPHIN and SAMOS.

Oil-free or oil-lubricated for gas recovery?

The manufacturers name both: Busch the oil-lubricated R5, the dry COBRA and MINK and the liquid ring vacuum pump DOLPHIN; Edwards the oil-lubricated, explosion-proof nES Ex, chemical dry pumps, liquid ring compressors of the LR series and, for helium, the dry XDS, nXRi and EXS; Leybold the dry ECODRY for helium. For expensive or pure gases, Leybold (leak rate) and Becker (gas-tight) speak of tight circuits.

How much vacuum does gas recovery need?

Tightness and throughput are named: Leybold a leak rate below 5×10⁻⁸ mbar·l/s for ECODRY 65 He plus, Edwards up to 52 m³/h of helium for nXQ55i, Busch 20–70 % of the H₂ feed in recirculation.

Why explosion-proof pumps for vapour recovery?

Vapours from oil and gas plants are flammable. For vapour recovery, Edwards names the explosion-proof nES Ex alongside LR compressors and chemical dry pumps; for vapours from storage tanks, Busch names COBRA, DOLPHIN and R5.

A single pump or a central vacuum system?

A central system in a room of its own keeps noise and heat away from production and matches its output to the demand. Central vacuum systems are planned and built by Eugen Theis Vakuum, a company of the Ehrler & Beck group – more under Central Vacuum.

Does Ehrler & Beck also supply spare parts and service?

Yes. Ehrler & Beck offers original spare parts and accessories as well as maintenance and repair.
