Wherever toxic or inflammable chemicals are being manufactured, processed, stored or shipped, an accident or a substance release is a potential risk. Even small releases of substances can cause harm to people, damage the environment or property. Hence, the use of the canary in providing potential warning for miners and its equivalents in today’s technological age. Industrial plants are not designed to leak toxic or flammable gases. However, each piece of equipment used in a process line does have a potential to leak, especially if service routines are not maintained. In each industrial plant there are thousands of devices and pieces of equipment used such as gauges, valves, pumps, compressors and storage vessels. Each joint or connection point is a potential source of release. The goal is to detect an accidental release before it develops into a major hazard. Toxic gas detection technologies Toxic gases and vapours can build up, reaching hazardous concentrations. Alternatively, there may be a lack of oxygen in the air that can be just as harmful to human life, plant and equipment. A plant owner needs to entrust the safety and protection of his personnel, equipment and property to a perfectly working sensor since human sensory organs are often unable to detect airborne hazards and, even when they do, are not able to do so early enough. Hazards must be identified in good time and reliably where false alarms that lead to production downtime are to be avoided at all costs. So the sensor is the most important component inside a gas detection system. It converts the measured variable (i.e. a gas concentration) into an electrical signal. Depending on the sensor type, this is achieved by either chemical or physical processes. To a large extent, the reliability with which harmful airborne substances can be detected depends on the sensors that are used to detect them. For this reason, it is essential for the gas detector and sensor to be adapted perfectly to each other.
Instead of avoiding their ignition by explosion protection measures, it is preferable to detect flammable gases before they become ignitable. Flammable gas detection technologies Most explosion hazards arise from flammable gases and vapours. Instead of avoiding their ignition by explosion protection measures, it is preferable to detect them before they become ignitable. The transmitter is a gas detector that continuously monitors flammable gases and vapours in the ambient air. The gas concentration that is detected in a range lower than the Lower Explosive Limit (100% LEL) is converted to an industry standard 4 to 20 mA signal. Central controllers and control panels are used to evaluate the signal and activate automatic counter measures and alarm devices according to the pre-programmed cause and effect matrices. Flame and heat detection Image courtesy of Dräger There is no such thing as a perfect flame detector. All have their own strengths and limitations. The correct application of detection technology is key to effective detection. There are four detector options available with ESI: ❚ Infra Red Flame Detectors (IR) ❚ Ultra Violet Flame Detector (UV) ❚ Combined UV & IR Detector ❚ Visual flame detection Visual flame detection was developed out of a need to create a detector that was spatially aware, allowing for the ability to discriminate between a large number of small sources Fire & Gas Detection within its field of view and one relatively large, bright event. The application behind this requirement was FPSOs. The areas that are adjacent to the process relief flare need protection. Flaring has caused numerous shutdowns by conventional radiation flame detectors because they are unable to discriminate between the two events.
