Sixty years of wet scrubbing.

A wet scrubber cleans a gas stream by bringing it into contact with a scrubbing liquid. The contaminant is absorbed, neutralized, or knocked out of suspension, and clean air leaves the stack.

It is a simple principle with an unforgiving detail: the scrubber itself lives inside the corrosive stream it is cleaning. Steel and coated systems handling acidic, alkaline, and chlorinated exhaust corrode in months. An FRP scrubber, with the resin and corrosion barrier specified to the actual service chemistry, runs for decades.

That is the problem Masterscrubbers were built to solve. Precisioneering has refined the line since 1964 across steel pickling, plating and anodizing, fertilizer, mining, chemical, pulp and paper, pharmaceutical, food, and odor-control duty.

No two streams are the same. The contaminant, its concentration, the carrier-gas chemistry, the removal target, and the headroom on site all change the answer. Every Masterscrubber is engineered to those conditions, not selected from a catalog.

02 — The Masterscrubber Families

Fume, gas, particle.
Matched to the stream.

Every Masterscrubber is matched to the contaminant — fume, gas, or particle — and to the chemistry of the stream it runs in. Three families cover the range; the right family and configuration are reviewed case by case against your application.

Impingement

Fumemaster

Compact impingement scrubbing, captured close to the source.

Fumemaster units collect fumes, mists, and liquid entrainment from process exhaust. A compact impingement-type scrubber, it captures contaminants close to the source, where a full absorption tower would be oversized for the duty. Where the stream carries recoverable plating chemistry, that recovery can be designed in.

Configuration: Compact impingement scrubber, close-coupled to the process
Typical duty: Plating, anodizing, and similar metal-finishing operations
Typical stream: Acid and alkali fumes, mists, and liquid entrainment

Absorption

Gasmaster

Mass-transfer absorption, matched to the gas and the headroom.

Gasmaster towers absorb and react with soluble gases. Packed-tower, crossflow, and sieve-tray configurations are each matched to the gas, the removal target, and the headroom available on site — crossflow units suit low-headroom installations where a vertical packed tower will not fit.

Configurations: Packed tower · Crossflow · Sieve-tray
Typical gases: Hydrochloric acid, sulfur dioxide, ammonia, chlorine, sulfuric acid, and others
Typical duty: Fertilizer, chemical, and pulp-and-paper plants

Venturi

Particlemaster

High-energy venturi capture for heavy particulate loads.

Particlemaster scrubbers capture heavy loads of fine particulate and liquid particles, and absorb soluble gases at the same time. Venturi-cyclone and water-jet-eductor configurations handle the high-energy duty that impingement and absorption units are not built for.

Configurations: Venturi-cyclone · Water-jet-eductor
Typical duty: Mining, fertilizer, smelting, and chemical operations
Also serves: Food processing, chlorine rooms, and semiconductor exhaust

03 — Decarbonators

CO₂ stripping for process liquids.

A decarbonator is a scrubber run in reverse — it pulls dissolved carbon dioxide out of a process liquid rather than a contaminant out of a gas.

After acidification — routine ahead of ion exchange and through much of water treatment — bicarbonate in the water converts to dissolved CO₂. Left in the stream, it loads downstream equipment and degrades resin performance.

A decarbonator works on the same principle as a wet scrubber: the liquid flows down through a packed tower against a forced draft of air, and the CO₂ transfers out of the water and into the airstream. The result is low-CO₂ water delivered to the next stage of the process.

Precisioneering fabricates decarbonator towers to customer-supplied design and specification — we build the FRP tower for the same corrosion reasons as the rest of the scrubber line, with resin and corrosion barrier matched to the duty, but the process design comes from the customer.

Principle: Forced-draft packed-tower stripping
Service: Dissolved CO₂ removal from acidified process water
Construction: FRP, resin and corrosion barrier matched to the duty
Scope: Fabrication to customer-supplied design and specification
Typical use: Ahead of ion exchange and through water treatment

— Engineered to the Chemistry

The stream sets every decision.

Every Masterscrubber starts with the stream. The resin system and corrosion barrier are selected case by case for the service chemistry — there is no default. Internals — packing supports, distributors, and demisters — are specified to the duty in FRP and CPVC. Airflow and tower sizing are engineered to the project and reviewed case by case.

Where a stream carries recoverable value — plating chemistry, for instance — recovery can be designed into the system, so the scrubber lowers disposal cost rather than only adding to it.

04 — Where Masterscrubbers Run
