scanfeld™ - The early warning solution for hazardous gas leaks
scanfeld is the world`s first early warning solution for comprehensive monitoring of entire chemical parks. Wherever gas accumulates, scanfeld™ identifies, localizes and images the gas cloud. Completely automated, around the clock.
Conventional sensors work like the sense of smell, which can only pick up a signal if they are directly where the gas is. In most cases, however, it is not clear where the invisible gas accumulates. The result: Over one third of major gas releases are not detected by traditional gas sensors.
The scanfeld™ early warning system uses remote sensing, or measurement at a distance. It works more like a watchtower. Even large areas with production and storage facilities can be monitored remotely for hundreds of compounds, 24/7, up to several kilometers away, and in any altitude profile, with no calibration needed. Gas distribution and propagation direction is made visible in real time. The system reacts to a wide concentration range – from single-digit ppm to double-digit percentage values, which helps distinguish safety related events from technical emissions.
The scanfeld™ sensor unit scans the air space of the entire factory, night and day. Gas distribution within the gas cloud is completely measured – no matter the distance, concentration or number of compounds. The chemical composition is analyzed by FTIR spectroscopy and thus the gas is identified.
The concentration distribution of the gas cloud becomes visible in real time and alerts the user of an incident; the warning includes the specific indication of how much of which gas is present. The scanfeld™ imager user interface can be displayed on any device, including monitors in the control room and hand-held devices in the field. The user can scan through time, and quickly assess the development of an incident. Fast-forward mode and time-loop functions provide an overview in seconds.
Our system informs and warns the operator of dangerous leaks. Gas concentration and compound type determine the alert level, so technical leaks can be distinguished from relevant incidents. Information on indication, persistence, quantity and relevance is also available in real time as written text. The scanfeld™ profiler allows the integration of the scanfeld™ monitoring solution into the safety architecture of the control center via the DCS interface.
The software module scanfeld™ tracker provides map-based cloud tracking: it displays and tracks the gas cloud location, propagation and concentration in real time using GPS.
Speed - Every second counts
Whenever a process sensor indicates a potential malfunction, situation assessment needs to be quick and precise. In case of the leakage of hazardous gases, action must be taken immediately. Targeted action requires accurate information about the event and the exact location, extent and propagation of a gas cloud.
The early warning system scanfeldTM- Covers entire facilities – even over large areas.
- Detects gas leakage in seconds, for all compounds involved.
- Displays and tracks the location and size of the gas leak and the gas cloud on a map.
- All in real-time
When sensors report abnormal behavior of the plant, operators must weigh the possibly severe consequences: should the alarm be shelved until further clarification of the situation, or should the process be shut down immediately which causes high costs? The wrong decision might cost time for field investigation and put field operators at risk.
scanfeld™ provides early warning with specific information on the situation and enables control room operators to make the right decision to prevent a hazardous situation. With standard monitoring technology, evacuation plans orient along the main wind and predefined evacuation protocols, but without account for areas and movement of hazardous gas concentration. With the scanfeld™ monitoring solution, operators and first responders gain vital specific information about the location and the concentration distribution of the hazardous gas cloud, so mitigation measures can be coordinated effectively.
scanfeld™ provides you with secure, accurate information which you can institute immediate, effective measures which protect plant employees and the environment.
Quality
The scanfeld™ early warning solution provides comprehensive early warning detection for gas leaks. It provides first responders in the field with accurate information of a moving gas cloud in real time to coordinate mitigation measures to help prevent disasters.
With early warning, concise geographic situation assessment, and the coverage of all far-field effects of an accidental gas release, scanfeld™ provides three barriers to prevent hazardous situations in one solution.
Mitigating risk and minimizing the effects of accidental gas release saves costs on its own. But the remote monitoring approach of the scanfeld™ provides more safety than any other detection system with the fewest number of sensors.
scanfeld™ detects and quantifies any airborne substance by its infrared spectral fingerprint. Our primary focus is on hazardous gases which are either flammable or toxic (or both). These present potential dangers to environment, personnel, and surrounding population. For toxic industrial chemicals (TIC) the prevention of gas leaks is a paramount safety issue and regulatory requirement.
More than 400 compounds are currently in our database. This includes most typical bulk chemicals such as ammonia, hydrocarbons such as alkanes, cycloalkanes, and benzenes, haloalkanes, chlorofluorocarbons or butadiene as well as many other process gases and intermediate products.
