Gypsum industry news

US: Progress on two new flue gas desulphurisation (FGD) projects in Colorado and Indiana have been announced. Neumann Systems Group has completed 60% of its US$73.5m contract to install an emissions scrubbing system at the Martin Drake Power Plant in Colorado and the first stage of the Indiana-Kentucky Electric Corporation's US$670m pollution-control project at the Clifty Creek plant in Indiana is now operational. Both of these projects will increase the supply of FGD gypsum in the US.

Neumann Systems Group has a 2011 contract worth US$121m to design, build and install an emission-scrubbing system on two of the Martin Drake Power Plant's three power production units. The NeuStream system is designed to remove more than 95% of the sulphur dioxide from the emissions of the two units, as required by US Environmental Protection Agency (EPA) rules that take effect in 2017, and convert it to gypsum that can be sold for fertiliser and building materials.

At the Indiana-Kentucky Electric Corporation's Clifty Creek Power plant in Indiana, plant officials announced that one of its two new flue gas desulphurisation scrubbers has begun feeding exhaust gas to produce cleaner emissions. These scrubbers will remove up to 98% of sulphur dioxide emissions creating synthetic gypsum. The Clifty Creek plant has six 217MW units that will feed to two scrubbers. The second scrubber is scheduled to begin operations in May 2013. The project began in 2007 but was postponed from 2009 to 2011 due to the economic downturn.
