Several CO2 capture rigs and related materials characterisation equipment for the investigation of the performance of CO2 capture materials, are hosted within the Research Centre for Carbon Solutions (RCCS) at Heriot-Watt University. These bespoke rigs simulate actual flue or flue gases composition, and hence allows for the determination of the capture capacity of test materials, and optimisation of operational conditions, allowing for scale-up. The conventional rig consists of a water bath, a specifically designed reactor, a Coriolis flow meter and a hiden analytical HPR20 mass spectrometer. The reactor has an internal diameter of 0.6 cm and a length of 20cm, allowing for a sample size of 100-250mg. The microwave rig allows for optimisation of the operational conditions using this novel form of energy, and in current modification to allow working under dry and wet conditions. TGA instruments, TA Q500 and TA 5500 Discovery, provide optimum temperature of operation and kinetics parameters, such as the heat of adsorption and the selectivity to CO2 in complex atmospheres.
Two separate rigs for the dynamic studies of CO2 capture under different atmospheres are available. A conventional heating rig with the ability to work at both dry and wet conditions and for biogas upgrading evaluation, and a microwave heated rig for evaluation of new heating procedures. The microwave heated rig consists of a glass reactor inside a microwave oven which allows accurate control of temperature by modifying the energy given by the magnetron. This reactor is coupled to a Coriolis flow meter and a mass spectrometer. These bespoke rigs are hosted within a well-equipped research facility, and access to TGA, N2/CO2 adsorption, DVS, FT-IR, etc instruments are available to compliment the access to the capture rigs.
The Research Centre for Carbon Solutions (RCCS) at Heriot-Watt University, is an interdisciplinary world-leading engineering centre, inspiring and delivering innovation for the wider deployment of technologies needed to meet necessary carbon targets. The RCCS occupy over 350 m2, across ten separate and interlinked laboratories, with dedicated high-end analytical research instruments and many bespoke in-house designed systems and rigs for advanced research and process development dedicated to research into Carbon Capture, Storage, Transport and Utilisation, in addition to facilitating several projects in the fields of Low Carbon System and Negative Emission Technologies. Along with facilitating our core research activities, the RCCS welcomes Academic and Industrial collaborators, and offers external contract analysis services.
