We specialise in monitoring stack emissions from processes
involving the manufacture or use of paints, printing inks,
plastics and adhesives.
Our VOC and particulate emission testing procedures have
UKAS accreditation.
Although we are a Member based organisation located in the UK, our services
are also available to non-members worldwide.
Tim Sullivan who is responsible for PRA's stack emission
monitoring service has attained the MCERTS
stack emission monitoring personal competency certificate for
Level 2 (team leader) plus technical endorsements TE1 (particulate
monitoring by isokinetic sampling techniques) and T4 (gases/vapours
by instrumental techniques).
MCERTS
for manual stack emission monitoring has been developed by the
Environment Agency in collaboration with the Source Testing
Association to ensure good quality stack emission monitoring
data. The certification of personnel enables personnel carrying
out the stack emission monitoring to be formally certified as
competent based on their experience, training and examination.
We have carried out stack emission monitoring for firms
manufacturing:-
paints
resins
polymers
printing inks
automotive components
military vehicles
aircraft parts
office furniture
graphic art materials
rubber goods
computer hardware
Our overall objective is to assist firms in complying with
Safety, Health, and Environmental legislation, while maintaining
or improving process efficiency. We recognise that our clients
need us to find solutions, rather than just define problems and
we are fortunate in being able to call upon the extensive
experience within the Association of all aspects of surface
coating technology.
We normally carry out an on-site assessment visit prior to
monitoring. This enables us to check for safe access and to
ensure that the location of the sampling points complies with the
recommendations of BS 3405. It is also important to ensure that
the monitoring work is scheduled for a time when normal
production is under way.
VOC Emission Monitoring
The total VOC emission concentration is measured using a total
hydrocarbon flame ionisation detector in accordance with BS EN
13526 "Determination of the mass concentration of total
gaseous organic carbon in flue gases from solvent using
processes". Monitoring is usually carried out over the
period it takes to complete the process being monitored.
VOC emission measurements can be used to:
assess compliance with emission limits set by the
appropriate regulatory body (i.e. Environment Agency or
Local Authority) in the company's process permit;
check effects of modifications to the process on the
emission levels; and
evaluate the performance of abatement equipment.
Particulate Emission Monitoring
The particulate emission concentration is measured in
accordance with BS 6069 section 4.3 "Method for the manual
gravimetric determination of concentration and mass flow rate of
particulate material in gas carrying ducts". This test
method is UKAS accredited. We can also carry out particulate
measurements in accordance with BS ISO 9096 "Manual
determination of mass concentration of particulate matter".
This test method is not UKAS accredited at present. Both test
methods rely on iso-kinetic sampling (i.e. using a gas sampling
rate such that the gas velocity at the sample nozzle is equal to
the gas velocity in the stack at the point of sampling) to ensure
that a representative sample is collected.
As in the case with VOC emission monitoring particulate
measurements can be used to :
assess compliance with emission limits set by the
appropriate regulatory body (i.e. Environment Agency or
Local Authority) in the company's process permit;
check effects of modifications to the process on the
emission levels; and
evaluate the performance of abatement equipment.
Consultancy Services
In addition to carrying out VOC and particulate monitoring, we
will be pleased to advise on the most efficient and cost
effective methods of complying with the appropriate emission
concentration limits. In particular we can tell you about the
advantages and limitations of:-
changing the operational procedures
using alternative materials
installing or modifying abatement equipment
We are very experienced with working for small companies where
money is simply not available for re-equipping the factory or
installing state of the art abatement equipment. We can usually
suggest a practical, low-cost solution that will enable you to
maintain production and work within your current emission limits.
