This project aims to develop low-cost instrumentation to enable process companies to achieve environmental compliance more cheaply. Emission and imission monitoring will be designed for easy integration into the higher system level.
The main objectives of the project are to:
- develop low-cost, high accuracy and high reliability sensors for comprehensive atmospheric emission and imission monitoring
- provide a significant improvement in data collection
- address the key generic monitoring needs identified by the TENPRO (6169) project.
Emission monitoring will be achieved by developing advanced semiconductor gas sensors. Novel semiconductor materials and constructions will be allied with embedded signal processing techniques to produce self-validating instruments for process operating environments.
Imission monitoring will be addressed by a device using OTIM (optical transform image modulation). The key advance in the basic technology is the use of ambient radiation for excitation, rather than cumbersome laser/reflector arrangements. This enables low-cost passive monitoring of wide areas in the open atmosphere. This will be developed together with array detection in a form suitable for deriving gas dispersion images in real time, thus providing a completely new and valuable capability in the field. This will be enhanced and developed together with the embedded signal processing needed to provide measurements in an industrially usable form. Just one system will provide a similar quality of information as supplied by hundreds of point sensors.
