Stack Emission Services
Our services for monitoring stack emissions include isokinetic measurement of particulate matter, velocity, temperature and pressure profiles. Levego’s services extend further to particulate matter and fume extraction plant balancing, gas cleaning plant efficiencies, dynamic particulate matter emission monitoring, calibration of automated measuring systems, and gas producer performance.
Levego is uniquely positioned to offer its clients a comprehensive independent calibration service for all makes of online continuous emission monitors according to BS EN14181:2004 and the US EPA Relative Accuracy Testing Audit (RATA) protocols and requirements.
Measurement services for the following are also offered, but not limited to:
- CO, CO², SO², SO³, NO×, NH³, HF, HCl, Cl²
- metals emissions
- volatile organic compounds (e.g. BTEX)
- semi-volatile organic compounds (SVOC)
- Polychlorinated dibenzo-p-dioxins (PCDD) and polychlorinated dibenzofuran (PCDF), amongst others.
Laboratory Services
Determination of particulate matter and sulphate analysis take place in our in-house ISO 17025:2017 accredited testing laboratory
Levego offers a comprehensive array of environmental analyses, including the supply of specialised sampling media that is outsourced to a carefully selected group of national and international accredited laboratories.
Equipment Supply
Levego can provide a range of portable analysers as outlined below:
- Portable combustion and emission analysers
- Portable flame ionisation analysers (FID)
- Isokinetic and gaseous stationary source emissions measurement equipment
- Toxic gas analysers
- Portable fourier transform infrared analysers (FTIR)
The above are used at various industrial emission sources e.g. refineries, chemical plants, boilers and furnaces.
Ambient Air Quality
We offer dust fall-out monitoring in accordance with ASTM D1739: 1970.
We co-ordinate the installation of compliant fall-out stands, site maintenance and collection of samples at the prescribed pre-determined intervals. Samples are collated and analysed in accordance with ASTM D1739 of 1970.
Levego’s ambient outdoor environmental air quality monitoring is performed using Radiello™ passive/diffusive samplers for the following contaminants:
- BTEX/VOC, aldehydes, ammonia, hydrogen fluoride, nitrogen dioxide, sulphur dioxide, ozone, phenolic compounds, hydrogen chloride, etc.
We also offer an odour control solution. The service includes odour assessments, odour surveys, sampling, analysis and odour modelling. Our partnership with international leaders in this field ensures that Levego has a solution to meet all of your odour emission requirements.
NAEIS Reporting
Levego offers assistance with the completion of your submission requirements to the South African National Atmospheric Emissions Inventory System (NAEIS). The NAEIS is an online national reporting platform aimed at holding both air pollutants and greenhouse emissions inventories for the Republic of South Africa.
Leak detection and repair
Leaking equipment, such as valves, pumps, and connectors, are a large source of emissions of volatile organic compounds (VOCs) and volatile hazardous air pollutants (VHAPs).
We offer a leak detection measurements service following the requirements of US EPA Method 21 and international best practice.
