Chemical Scrubbers

All ERG designs are bespoke and matched to the detailed requirements of the application specification
ERG uses industry-standard random packing to optimise operating efficiency with system pressure drop and equipment size
All packages carry a performance guarantee and are designed to provide robust operation at the lowest capital and operating costs

Our extensive design and operating experience enables us to optimise the system performance.

Flowrate ranges from 100 to 100,000 m³/hr per tower, multiple towers in parallel can be used for higher flowrates
Odour loadings up to 1,000,000 ou_E/m³ are common
Soluble contaminants typically 50-200ppm average, and up to 1,000ppm peak
Typical removal effciency 99.5%, up to 99.95% as required
Vessel diameters from 200 to 3,800mm, heights typically up to 10m, or higher if the process requires it

Complete systems supplied including recirculation pump, pipework, fan, ductwork, access platform, instrumentation and control system – and may be integrated further with a carbon filter
Commonly used packing types include Snowflake/AstraPAC and 1″, 1.5″ and 2″ Pall rings
Recirculated liquor flowrate selected to minimise pump flow and energy consumption at optimal scrubbing performance
Liquor distribution across packing using sprays or trough distributors depending on application
Droplet elimination using chevron, impaction blade or woven mesh design to suit application – clean in place sprays available to assist with on-line maintenance
Scrubber sump tank integrated into the packed column vessel
Chemical dosing, water make-up and blowdown control to match specific performance requirements
Instrumentation selection to give robust operation, high reliability and tight performance control
Vessel designed as standard to BS EN 13121 or BS 4994
Materials selection to suit contaminants and reaction chemistry: common materials include uPVC, PP, Derakane® GRP, Crystic® GRP
