Wherever large quantities of dust are stored, transported or mixed – in industries such as chemical, food, cement or water treatment – the risk of explosion must be controlled. Mixed with oxygen from air the small particles can easily ignite. Although every plant is different, the fundamental safety requirements of controlling oxygen levels is the same.
Most operators prefer a complete solution for controlling and monitoring Oxygen (O2) and Carbon Monoxide (CO), rather a set of separate analyzers. A complete packaged system is guaranteed to work efficiently and not all plants will have personnel who are sufficiently trained to operate and maintain different systems or have the resources to deal with several manufacturers.
In some water treatment plants sewage sludge can be dried with a combination mechanical pressing and heated air. Both CO and O2 have to be monitored in the silos where this process takes place. The de-watering and drying of sewage sludge produce dust and large amounts of dry end-product which increases the risk of explosion.
In this application it is ideal to have a single product that can monitor multiple gases. PST can offer customized analyzer packages that can be designed specifically to customers’ needs. In our Case study on sewage sludge dryers you can find out how Michell Instruments offered a solution using their the XTP601 thermo paramagnetic oxygen analyzer with a CO analyzer. The XTP601 now meets the requirements of IEC61508 SIL2.
