Process control and emission monitoring in a cement plant is a challenge. A large number of gaseous components need to be measured with high accuracy in a dusty and corrosive environment. The monitoring system needs to be easy to maintain and fast to calibrate. To use an extractive system in this environment will demand a lot of maintenance. The OPSIS system is different and provides the cement plant with an accurate analyser that will operate with high performance and a minimum of maintenance.
The OPSIS system is based on a non-contact DOAS/FTIR method, using an optical 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, HCI, HF, NH3, CH4, and Hg.
