ERG (Air Pollution Control) has set up a flue gas desulphurization (FGD) system for the Ferrybridge carbon capture pilot project.
The FGD system is used at the final polishing phase to minimize sulfur dioxide (SO2) and particulate concentrations before the flue gas is transferred to a post combustion carbon capture unit. This unit will eliminate 100 t of carbon every day from the flue gases that are generated by the Ferrybridge power station.

The ERG system is equipped with a direct contact packed tower cooler and a two-stage “polishing” tray scrubber. The cooler and scrubber are constructed to ERG's specification and each one has 2 m diameter and 9 m height. The system will treat approximately 30,000m3/hr of flue gas and will remove 80 to 90% of SO2 and particulates.
The UK-based company has also delivered additional equipment, including ancillary instrumentation and control tools, scrubbing liquor storage tanks, a fan and recirculation pumps. The Ferrybridge project, which captures carbon is a pilot trial to validate the technology for post carbon capture by subjecting it to the side stream of the flue gases from the power plant of 1% and its completion further strengthens ERG's leadership position in the design and distribution of industrial air pollution control solutions. The installed FGD unit will commence operation in 2011.
Last year, ERG has completed several major industrial projects, including a silicon tetra-fluoride scrubber for production of phosphate fertilizers in Egypt, a hydrochloric acid fume scrubber for Kazakhstan-based petrochemicals refinery and a methane conditioning plant for the fertilizer production facility in Qatar.
