Economic activity introduces pollutants into the atmosphere
posing threats to human health and other life forms. The measuring
of pollutants, regularly and accurately, constrains law
enforcement of existing adequate legislation regarding emissions.
Current technology cannot measure accurately in space and time
simultaneously and there is therefore a need for integrated
sensing equipment that can provide this simultaneously for both
gaseous chemicals and particulates.
The project aims to establish a unique
laser-based integrated sensor technology with embedded electronics
and software which will support industrial decision makers and
regulators to measure and manage air quality. The envisaged laser
technology is potentially more flexible and cost effective, with
more advantageous features than existing air quality measurement
equipment, such as spatially resolved measurements of particulates
and gases.
The project will involve the design, assembly
and development of the laser-based sensor system, followed by
testing of the system on site in industrial areas in Sasolburg and
Secunda as well as testing in a metropolitan area in the Vaal
Triangle. Finally the dispersion models and stack data, as
measured by industry and authorities, will be validated. Numerous
social, technical and economic benefits are envisaged for the
technology, and the commercialisation plan includes international
licensing and supply of customised systems and services to
industry and authorities. |
