US: FCT Combustion has reported service updates to its clients in Ecuador, the US and Canada.

Hormicreto in Cuenca, Ecuador is preparing for commissioning of its G-Jet Hot Gas Generator for alternative liquid fuels firing, with a thermal capacity of 5.2MW. The system will provide hot air for the raw and cement swing mill application. FCT is responsible for the complete supply from the waste oil tank to the hot gas generator. Hormicreto is also commissioning a new riser duct natural gas firing system. FCT has also supplied two K-Jet Calciner Burners at the riser.

The Lehigh Cement Leeds plant in Alabama, US has awarded FCT with a new contract for a natural gas firing system for their riser duct. The system, rated at 30MW, will consist of a NPFA 86 Valve Train and K-JetCalciner Burner.

St Marys Cement, part of the Votorantim Group, has ordered, via Arctic Combustion, two K-Jet Calciner Burners for natural gas at the riser for its Ontario, Canada plant. The K-Jet Burner has a cutter block system that adjusts gas velocity on the fly during operation.

The CRH Mississauga plant in Canada has hired FCT to make an audit of several of its pieces of combustion equipment of the plant.

US: The Environmental Protection Agency (EPA) and the Department of Justice (DOJ) have agreed a settlement with Cemex, under which the company will invest approximately US$10m to cut air pollution at five of its cement plants to resolve alleged violations of the Clean Air Act. Under the consent decree lodged in the District Court for the Eastern District of Tennessee, Cemex will also pay a US$1.69m civil penalty, conduct energy audits at the five plants, and spend US$150,000 on energy efficiency projects to mitigate the effects of past excess emissions of nitrogen oxides (NOx) from its facilities.

“This settlement requires Cemex to use state-of-the-art technology to reduce harmful air pollution, improving public health in vulnerable communities across the South and Southeast,” said Cynthia Giles, Assistant Administrator for EPA’s Office of Enforcement and Compliance Assurance. “EPA is committed to tackling clean air violations at the largest sources, cutting the pollutants that cause respiratory illnesses like asthma.”

The five Cemex cement plants affected by the deal are located in Demopolis in Alabama, Louisville in Kentucky, Knoxville in Tennessee and New Braunfels and Odessa in Texas. The Knox County, Tennessee and Louisville, Kentucky air pollution control authorities participated in this settlement. Cemex is required to install pollution control technology that will reduce emissions of NO_x and establish strict limits for sulphur dioxide (SO₂) emissions. The cement producer will install and continuously operate a selective non-catalytic reduction system for controlling NO_x at the five plants and meet emission limits that are consistent with the current best available control technology for NO_x. EPA estimates this will result in NO_x emissions reductions of over 4000t/yr. Each facility will also be subject to strict SO₂ emission limits.

This settlement is part of EPA’s National Enforcement Initiative to control harmful emissions from large sources of pollution, which includes cement plants, under the Clean Air Act’s Prevention of Significant Deterioration requirements. The total combined SO₂ and NO_x emission reductions secured from cement plant settlements under this initiative will exceed 75,000t/yr once all the required pollution controls have been installed and implemented.

The settlement is subject to a 30-day public comment period and final court approval.
