FTIR Gas Analyser Supports Carbon Capture Research
The development of carbon capture and storage (CCS) technologies relies on the accurate measurement of carbon dioxide (CO2
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
An advanced FTIR multiparameter gas analyser from Gasmet Technologies is therefore being employed at the UK Carbon Capture & Storage Research Centre (UKCCSRC) facility near Sheffield. This Pilot-scale Advanced Capture Technology (PACT) facility was created to catalyse and support industrial and academic research to accelerate the development and commercialisation of novel technologies, to bridge the gap between bench-scale R&D and industrial pilot trials, and to provide shared access to industry and academia.
Background The combustion of carbon-based fuels creates CO2 which is an
important greenhouse gas and contributes to global warming. Growing atmospheric levels of CO2
also have other effects such as
ocean acidification and there are a number of global initiatives to reduce CO2
emissions. For example, the UK has a legally binding
target to lower greenhouse gas emissions by at least 80% (from the 1990 baseline) by 2050. This can be achieved by switching to renewable sources such as biomass, solar, wind and tidal energy, by utilising energy more efficiently and by the development of low-carbon technologies such as CCS.
CCS is able to remove up to 90% of the CO2 emissions from
combustion and power generation plants by first capturing carbon; second transportation and thirdly deposition in a selected geological rock formation that is typically located several kilometres below the earth’s surface - in depleted oil and gas fields or deep saline aquifers for example.
There are three possible methods for carbon capture: pre- combustion capture, post-combustion capture and oxyfuel combustion. However, these technologies need to be developed and trialed on a pilot-scale before they can be implemented in new or existing facilities.

The UKCCSRC PACT facilities are funded jointly by the Engineering and Physical Sciences Research Council and the Department of Energy and Climate Change with 6 University partners: Cranfield, Edinburgh, Imperial, Leeds, Nottingham and Sheffield. They provide specialist national facilities for research in advanced fossil-fuel energy, bioenergy and carbon capture technologies, including a comprehensive

important that the process does not impact upon the emissions of other greenhouse gases and potential pollutants.
range of pilot-scale facilities, specialist research and analytical facilities, all supported by leading academic expertise.
The Beighton site near Sheffield provides researchers and industry with pilot-scale facilities for all three of the carbon capture methods and PACT Business Development Manager Dr Kris Milkowski, from the University of Leeds, says: “FTIR gas analysis performs a vital role in our work with all of these methods; enabling us to monitor CO2
levels in addition to almost any
other gas from the Gasmet library of over 5,000 compounds. For example, in addition to CO2
it is also necessary to check for solvents and any degradation products that may be present.

“Previously, we utilised racks of single-parameter analysers but this limited our work to a small number of gases, whereas the possibilities with FTIR are almost endless. Not only do we have the ability to identify unknown peaks in the data, but we also have the facility to analyse recorded spectra retrospectively, which means that, in the future, we will be able to measure compounds that we were not necessarily of interest at the time the analysis took place.
“The flexibility of the DX4000 system is extremely important for our work because each programme of research studies different aspects of combustion control and carbon capture, so the ability to specify measurement parameters for each programme is a major advantage.
“The portability of the analyser is also a great benefit because it can be quickly relocated when necessary, including deployment at industrial sites and with a transportable CCS system that is based in Edinburgh. This unit is capable of processing 25-50 m3
of flue
gas per day and runs a number of small scale test units operated in parallel to reproduce capture processes conditions.”
The Gasmet DX4000 FTIR analyser was supplied and configured by Milton Keynes based Quantitech. “The system was delivered with a sampling system and heated sample lines so that hot, wet and even corrosive gases can be measured,” says Sales Director Dominic Duggan. “Similar systems have already been supplied to full-scale CCS systems, so we were delighted to be involved with the PACT facility which we believe will make a major contribution to the development of CCS in the UK and beyond.”
