We Perform
Compliance Monitoring
Enviro Protek Consultants Services is a private environmental consultancy that performs compliance monitoring to assess whether organisations operate within environmental regulations.
Enviro Protek Consultants is passionate about the environment and about serving others. We are a team of Chemical Engineers that specialise in Carbon Accounting, Air Quality Compliance, and Emissions Measurement, and we love our work.
Stack sampling or Isokinetic Stack sampling is one of the main measures for determining the particulate matter (PM) load in a stack, often for environmental compliance with Atmospheric Emission Licences (AEL), new applications and renewals.
Almost all industrial installations worldwide have a requirement to know and monitor their emissions to atmosphere, and take steps to reduce or limit their emissions. The quantities of gases that plants are permitted to emit are enforced by local regulation in each geographical region and can vary on the type of industry, plant or fuel that is being burnt.
In order to monitor the emissions, increasing instrumental techniques are the preferred method and certainly where a continuous emissions monitor is needed this can only be from on-line analysers. Enviro Protek Consultants has developed our range of gas analyser to operate within the stringent levels of performance needed in order for industry to monitor the emissions as required by the regulations. This includes the need for certification or accreditation of the analysers against performance requirement

Government legislation requires different gas measurements in a stack for different processes as per the Section 21 NEMAQA, Scheduled Processes:
A typical and often common example is for the stack measurement of small to medium size boilers: NEMA: Section 23(1): Small Boiler as a Controlled Emitter, combustion installations would require measurement of PM and SO2.
