Jet Scrubbers
How the Process Works
- Side inlet – Contaminated gas enters horizontally.
- Liquid injection – A liquid motive jet accelerates the gas and raises the pressure.
- Cylindrical reaction zone – The motive fluid is dispersed by a nozzle, forming a cone that spans the full diameter of the scrubber’s cylindrical ejector section, providing a large contact area between gas and liquid.
- Separation tank – Gas and liquid phases are separated; sludge or impurities are drained.
- Mist eliminator – Fine liquid droplets are captured before the clean gas continues.
Performance data for our jet scrubbers
Parameter | Typical range |
Gas flow | 60 – 100 000 m³/h |
Liquid consumption | 5 – 65 L per m³ of gas |
Liquid pressure | 1.5 – 5 bar(g) |
Relative velocity | 10 – 25 m/s |
Pressure rise / Δp | 3 – 40 mbar |
Dust removal (1 µm / 10 µm) | 55 % / 99 % |
Absorption efficiency | > 99 % for soluble gases |
Energy consumption | 0.6 – 7.5 kWh per 1 000 m³ |
A 300 m³/h pilot plant is available for field tests and sizing.
Advantages of Jet Scrubbers
- Self-priming—replaces a mechanical fan
- Simple, compact construction
- Low maintenance, high reliability
- No fire risk thanks to fully wet operation
- Can be arranged in multiple stages for very high removal demands
Typical Applications
- Fan-less gas conveyance
- Direct “quench” cooling of hot process gases
- Absorption of SO₂, Cl₂, HCl, NH₃, HF, H₂S, etc.
- Removal of dust particles > 3 µm
- Recovery of valuable substances from gas streams
Sizes & Materials
Standard sizes DN 80–DN 1 000 cover 60 – 26 000 m³/h. Custom designs up to 100 000 m³/h are available as single- or multi-stage solutions; installations exist up to 300 000 m³/h and 1 000 °C.
Materials of construction
- Carbon steel, stainless steel
- Steel lined with rubber, PVDF, PTFE or Halar®
- Plastics (fiberglass, PP, PVC, PVDF)
- Special alloys for corrosive environments
Pilot Equipment
A transportable pilot scrubber (≈ 300 m³/h) allows on-site verification of separation efficiency and energy requirements before investment.
