FTIR ANALYSER BENEFITS The Gasmet DX4000 FTIR analyser was supplied and configured by Milton Keynes based Quantitech. It was delivered with a sampling system and heated sample lines so that hot, wet and even corrosive gases can be measured. Highlighting a further benefit of PACT’s relationship with Quantitech, Milkowski said: “The availability of rentable Gasmet FTIR systems from Quantitech is important because most of our projects incur a substantial investment in resources within a tightly defined time-scale, so even though we have not yet had cause to make use of a backup system, it is comforting to know that FTIR systems could be made available at short notice if necessary.”


SOLVENT ABSORPTION The UKCCSRC PACT site at Beighton includes a Solvent-based Carbon Capture Plant (SCCP) which enables the development, evaluation and optimisation of a variety of solvents for post- combustion capture. It is designed to remove up to one tonne/day of CO2


from an equivalent of approximately 150kW


conventional coal combustion flue gas. The plant incorporates an 8m absorber


column equipped with temperature and differential pressure sensors, solvent sampling ports, provisions for corrosion coupons and alternative materials test sites, and trace gas injection capability. It also has an integrated flue gas desulphurisation carbonate wash system. Typical flue gas CO2


levels following


coal combustion are around 12% and, depending on the solvent and the flow rate, the concentration following carbon capture is about 1%. The SCCP is connected directly to the PACT combustion facilities which include a 250kW Air Combustion Plant and the 300kW Gas Turbine System, enabling post-combustion capture research from real flue gases from natural gas power plants as well as pulverised fuel combustion plants including coal, biomass and co-firing. The facility is also connected to a dedicated gas mixing facility, enabling carbon capture from any synthesised flue gas compositions, including industrial effluent gas mixtures.


A FLEXIBLE SOLUTION “Dr Milkowski’s work with the Gasmet DX4000 analyser has clearly demonstrated the suitability of


multiparameter FTIR for monitoring CCS plants,” commented Dominic Duggan, sales director at Quantitech. “In most applications we would recommend a fixed continuous emissions monitoring system (CEMS) for such applications. However, as a research site, the PACT facility requires maximum flexibility in its resources – so the portability of this system is ideal for PACT’s work.”
