In a new white paper, Mettler Toledo explains the importance of choosing the correct sensors in scrubber applications. According to the company:
- Many chemical and petrochemical processes produce gaseous emissions that contain polluting substances such as sulphur dioxide and hydrogen chloride — if released into the atmosphere these compounds would violate regulations and cause serious environmental damage as both are components of acid rain.
- The principle of wet gas scrubbing is to bring the polluted gas into contact with a solution that contains reagents that absorb or "scrub" the unwanted compounds from the gas, creating cleaner emissions that can be safely released.
- Wet gas scrubbers are usually supplied with analytical sensors already in place, but it is often the case that the sensors are not robust enough to operate reliably in the harsh gas scrubber environment.
- The new white paper “You're Scrubbing, but Are You Clean?” discusses the above issues and outlines analytical sensor technology called Intelligent Sensor Management which, as a feature of the company’s sensors, results in increased scrubber efficiency and reduced scrubber operating costs.
