Process control and emissions monitoring in a brick plant is a challenge due to the high concentrations of HF. The HF is generated in the process and gas phase HF can reach 50 mg/m3 or more. To use an extractive system in this environment will demand a lot of maintenance.
The OPSIS DOAS system is different and provides brick plants with an accurate analyser that will operate with a minimum of maintenance. The OPSIS DOAS system is based on a non-contact method using an optical measurement path that can operate across the duct.
The optical light is transported in an optical fibre to the analyser and one analyser can operate several paths. A single OPSIS system will measure all relevant gas components such as NOx, SO2, CO, CO2, H2O, HCl, HF and others.
