ASK Piearcey Ltd have signed an Exclusivity deal with Plasticon UK Ltd covering odour control in the Sewage Treatment Sector.

The agreement means that ASKP Ltd and Plasticon can forge ahead with plans for development of their odour control strategies and are starting with some courses for process engineers in odour control techniques (watch out for news on this up and coming event).

The agreement is a formalisation of a successful working partnership which has developed over the last 3 years.

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.

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.

ASK Piearcey  generated the specification documents, managed the tendering stage and then coordinated this project on behalf of a Major Off-Shore company. The Catalytic Oxidser removes IPA solvent emissions from a drying process.

ASK Piearcey designed a 2 stage odour control system comprising a bio-scrubber followed by dual bedcarbon adsorbers.

The site had 2 off systems for treating off gas from Lamella separators. The systems were manufactured and installed by Plasticon UK Ltd,  ASKP Piearcey and Plasticon UK carried out the system commissioning. The system successfully removed odour from the streams and easily met the target outlet.

ASK Piearcey designed, managed and commissioned this dual stage odour control. unit using copper oxide impregnated carbon protected by a pre-filter unit.

The system controls emissions from the blow-down of a brand new autoclave cooking process to handle municiple waste. The unit completely removed the strong “chemical” odours from the non-condensible exhaust.

ASK Piearcey designed, project engineered and commissioned a single stage jet venturi scrubber with carbon polisher.

The jet venturi unit was manufactured by Transvac Systems Ltd and the whole system was installed by EIS UK Ltd The system removes high concentrations (13,000ppm) of chlorine  from hot reactor exhausts as well as entrained solids.

The system uses a caustic dosing system to regulate liquor pH. The Jet venturi provides the neccessary motive force to overcome its own pressure drop and that of the down stream adsorber set.

ASK Piearcey designed, managed and commissioned a laser cutter fume system to replace some old and expensive to run units.

A single carbon adosrber with 2 stage pre-filtration has reduced filter changes from daily to every 3 weeks and carbon changes from every 2 days to once annually (not changed as yet). Estimated cost savings >£10k per annum excluding the cost of down time.

The system treats approximately 800m3/hr of fume containing up to 25ppm HCl and VOC from the PVC sheet as it is laser cut.

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.

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.

ASK Piearcey have attained Diamond Status from their recent, indepedent customer satisfaction survey.

This is the top award in the BenchmarQ assessment and showed 100% of customer surveyed would recommend us to others.

 ”The award is greatly valued as it represents a huge pat on the back from our customers for all the hard work we have put in over the last 2 years”. – Andrew Piearcey MD.

The company has set the bar to the highest level and is already reviewing its quality procedures under its newly attained ISO9001 banner to ensure that these standards are maintained.

We would like to take the opportunity to thank our customers for their continued support over the last few years and hopefully for the future.
