Safety and interlocking gas analysis

In order to provide a safe working environment on any pyro plant, potentially dangerous conditions must be monitored and safely dealt with. Failing to do so will endanger plant employees and may damage or destroy costly machinery, resulting in a long-term production shutdown. Specially designed safety equipment is therefore available, which utilises true continuous analysis without purging periods and offers the option of redundancy. Special safety I/O’s are available depending on the safety standard enforced, and direct interlocking options for process equipment is available.

ROI: Interlocking of one potentially dangerous condition, e.g., high CO. Typical components measured: O2, CO, CH4, THC (others on request)

Take care of people and equipment

Given that safety is critical to any pyro process, we have developed solutions capable of handling even the toughest demands. All equipment for safety and interlocking purposes is based on a double probe layout. This allows one probe to be analysing while the other probe is being prepared to take over – enabling true continuous analysis without any blind periods.

For safety and interlocking applications only extractive analysis systems are used, since only in these systems can active sampling of live process gas can be confirmed by the active flow passing through the analyzers. We do use in situ solutions in other applications, but not for safety and interlocking purposes. The extractive system is also very easily adapted to safety zone issues, and hot surfaces as seen on some in situ analytical cells can be completely avoided.
