Reactor and paint fumes destroyed before they leave the plant
CRA's thermal oxidisers destroy the solvent vapour, reaction fumes and odour vented from resin reactors, thinning tanks and paint manufacture.

What does a thermal oxidiser do at a paint and resin plant?
Resin reactors and thinning tanks vent solvent vapour and fumes as each batch is cooked and thinned. The vents are collected and sent to a thermal oxidiser, which burns the solvent and the odour-causing compounds.
How it works
Condensers on the reactor vents remove most of the water first, and the oxidiser treats what remains.
Reactor, tank and mixing vents are gathered into a header.
Condensers take out most of the reaction water.
The oxidiser burns the solvent and fumes.
The cleaned gas is discharged through the stack.
Key Benefits
Solvent and reaction fumes from resin reactors are oxidised before discharge.
Odour from cooking and thinning is destroyed with the solvent.
The oxidiser follows the changing vent flows of batch reactors.
Reactors, thinning tanks and mixing areas can share one oxidiser.
The oxidiser is designed for destruction efficiency above 99%.
The CRA Edge
CRA has more than 30 years of experience in gas handling and flare engineering.
Design, R&D and manufacturing are carried out under one roof.
ISO 9001 certified through TÜV NORD, with designs aligned with ASME, API and CE.
Designs are customised to the process needs and the regulations that apply at site.

Frequently Asked Questions
Why do resin plants need a thermal oxidiser?
Resin reactors release solvent vapour and fumes with a strong odour. The oxidiser destroys them before they reach the air.
Can the oxidiser cope with batch reactors?
Yes. CRA designs the oxidiser for the changing flows and loads through each batch.
What happens to the water vapour from the reactors?
Condensers on the reactor vents remove most of the water, and the remaining vapour goes to the oxidiser.
What data does CRA need to size a resin plant oxidiser?
CRA needs the vent sources, their flows through a batch, the solvents and products involved, the emission limits and the site conditions.
Can paint mixing areas share the same oxidiser?
Yes, where the flows are compatible. Large, dilute flows from mixing areas may suit a regenerative unit.
