Wet scrubbers, sized against your duty
Every system below is a design, not a catalogue number. The ranges tell you what each type is suited to; the figures that apply to your installation come off a datasheet once we have your gas, your flow and the discharge condition you have to meet.
Compact fume cupboard scrubbers
Packed-bed scrubbers sized for one to four fume cupboards, built to fit the plant room you already have.
- HCl
- HF
- HNO₃
- H₂SO₄ mist
- NH₃
Packed tower scrubbers
The workhorse for soluble gases — counter-current or cross-flow, from a few hundred to tens of thousands of cubic metres an hour.
- HCl
- HF
- HBr
- SO₂
- NH₃
Odour control scrubbers
Chemical scrubbing for hydrogen sulphide, mercaptans, ammonia and the amine odours that generate complaints.
- H₂S
- Mercaptans
- NH₃
- Amines
- Organic sulphides
Venturi scrubbers
High-energy scrubbing for particulate, fume and sub-micron mists that a packed bed will not hold.
- Metal fume
- Process dust
- Acid mists
- Sub-micron particulate
- Soluble gases
Multi-stage scrubbers
Two and three stage systems for mixed process streams, where one chemistry cannot do the whole job.
- Mixed acid gases
- NH₃ with HCl
- Particulate with soluble gas
- Solvent mists
- H₂S
Controls, dosing & monitoring
The panel, the instruments and the dosing that keep a scrubber at its design duty between services.
SpecificationsWhich type suits which problem
| Soluble acid gases | Packed tower, or a compact packed bed at laboratory flows |
|---|---|
| Ammonia and amines | Packed tower on an acid liquor, usually as the first stage |
| Hydrogen sulphide and mercaptans | Alkaline oxidant stage, with carbon polishing near a sensitive boundary |
| Particulate, fume and mists | Venturi — a packed bed will blind on solids |
| Mixed acidic and alkaline streams | Multi-stage, one chemistry per stage |
| Existing plant that has drifted | Controls, dosing and instrumentation retrofit |
