Real-time Chemical Component Analysis for Monitoring and Optimising Process Performance
An innovative technique that enables continuous, real-time, in-situ component analysis and concentration measurements using proprietary software in combination with physical property sensors. This technique has applications in industrial carbon capture, gas desulphurisation, and gas sweetening process monitoring and optimisation.
- Carbon capture
- Gas desulphurisation
- Gas sweetening
Understanding chemical composition is critical to carbon capture plant operators, as well as in industries such as gas desulphurization and natural gas sweetening. This knowledge is used for monitoring and optimising performance. However, current techniques to obtain chemical compositions can be slow, limited to off-line application, require prior knowledge of chemical constituents that can degrade over time, are labour intensive requiring specialist staff, and require regular re-calibration.
This Edinburgh technology is based on an algorithm that allows rapid analysis of chemical composition inferred from physical property measurements. The software operates in conjunction with a conditioning system, and density and viscosity sensors. Rapid analysis of in situ samples delivers real-time online results. The technique requires no proprietary component details – only simple, non-identifying physical characteristics. Furthermore, the performance of the system is maintained as active components degrade over time, reducing the need to undertake regular re-calibration.
The technology has been successfully demonstrated at a variety of industrial carbon capture facilities. Proof of concept studies involve analysis of amine sequestration species and CO2 concentration. Under these real-life industrial conditions, the system has been shown to operate safely and continuously for extended periods, and provide accurate measurements, including for aged, degraded and non-ideal commercial solvents.
