Industrial VOC Abatement
ASK Piearcey designed a range of split bed rect-annular carbon adsorbers for the adsorption of methyl chloride on a coating process.
The equipment was manufactured to our designs by EIS Ltd
ASK Piearcey were asked to investigate the possible release of VOCs from a printing process. Smoke testing and flow measurement from ASK Piearcey demonstrated clearly that there were no fugitive emissions from the process. By investigating the prime VOC sources in the process ASKP Ltd were able to advise the client regarding minor extract philosophy changes to improve stack emissions, which were found to be compliant
VOC Abatement
ASK Piearcey were asked to provide designs for movable carbon adsorbers to assist in the removal of VOCS from combined vent and breather sources, some of which ere already treated via a scrubber. Modifications to the scrubber operation involving re-use of another waste water stream improved the scrubber performance and hence allowed for an improvement in design carbon bed life. The units are due to replace existing static adsorbers and will provide for easier carbon change and reduction in on site, associated hazards.
The project was under taken with Transvac Ltd who built the original scrubber.

Industrial Odour Control
ASK Piearcey designed the adsorbers for the removal of odour generated by the baking of pet food treats.
The adsorbers were then fabricated by the customer with ASK Piearcey Ltd assisting with the sourcing of the carbon. ASK Piearcey also assisted the customer with the choice of pre-filter to remove the oil aerosol present in the off-gas.
Absorbers
ASK Piearcey were asked to investigate the odorous releases from a high temperature autoclave sterilisation process. Tests were conducted for hydrogen sulphide and ammonia and then a full scale abatement system was designed to handle the fume and other extracts.

Sewage Odour Control
ASK Piearcey designed and commissioned this odour control system consisting of a pumice stone biofilter and copper oxide impregnated carbon unit.
The manufacture and installation is by Odour Services Ltd. The system treats around 70ppm of Hydrogen sulphide with 150ppm peaks lasting several hours.
For further information on Sewage odour call Andrew on 01909 518 837.
ASK Piearcey field testing for gas flow and H2S
ASK Piearcey Ltd were asked to provide commissioning schedules and carry out the commissioning/flow balancing of this odour control system in the North West of England. The system extracts from various sources around site and uses a caustic/hypochlorite scrubber followed by carbon adsorption (with humidity control) to handle the odorous emissions. The system was a turnkey project manufactured and installed by Plasticon U.K Ltd.
