Polyurethane Insulated Scrubbers
A polyurethane insulated scrubber is a pressure vessel designed to remove contaminants from gas streams through contact with a liquid scrubbing medium while maintaining controlled temperatures through integrated polyurethane foam insulation. These vessels ensure efficient mass transfer and contaminant removal by maintaining optimal temperatures for absorption and reaction processes.
Why are Polyurethane Insulated Scrubbers Needed?
Polyurethane insulated scrubbers are essential for gas cleaning applications where temperature affects absorption efficiency, chemical reaction rates, and scrubbing solution properties. Maintaining optimal temperatures maximizes contaminant removal, reduces chemical consumption, and ensures reliable environmental compliance.
Polyurethane Insulated Scrubbers Applications
Common applications include:
- Acid gas removal (H2S, CO2)
- SO2 scrubbing
- Chlorine scrubbing

Polyurethane Insulated Scrubbers Frequently Asked Questions (FAQs)
How does temperature affect scrubber performance?
Temperature significantly impacts absorption equilibrium and mass transfer rates in scrubbing systems. For most absorption processes, lower temperatures improve equilibrium but may increase solution viscosity and reduce mass transfer rates. Polyurethane insulation helps maintain the optimal temperature balance for your specific scrubbing chemistry.
What scrubbing solutions can be used with polyurethane insulated scrubbers?
Our scrubbers are designed for compatibility with a wide range of scrubbing solutions including amines, caustic, water, and specialty chemicals. Material selection for the vessel and internals is based on your specific solution chemistry, with options including stainless steels, nickel alloys, and corrosion-resistant linings.
Can scrubbers be designed for multiple contaminant removal?
Yes, we design multi-stage and multi-contaminant scrubbing systems with appropriate internals and solution circulation for each contaminant. The polyurethane insulation system is designed to accommodate the temperature requirements of each stage, with zone insulation where different temperatures are required.
