US: CTP Sinto America, the North American business unit of Chemisch Thermische Prozesstechnik GmbH (CTP), has entered into a contract with Holcim (US) to supply emissions reductions equipment for one of the cement kilns at Holcim's Midlothian plant in Texas. In the project, exhaust gases from the main baghouse and coal mill baghouse are combined and sent to the new system and then directed to the existing wet scrubber.
The project scope includes supply and installation of a CTP Model AutoTherm6-4200 designed to handle 420,000 Nm3/hr of gas and duct modifications required to route the gas to the regenerative thermal oxidiser (RTO) and return it to the exhaust. CTP Sinto America will provide engineering, manufacturing, project management, field operations, installation and commissioning. Controls will be integrated into Holcim's existing plant-wide DCS. The system will be ready for operation in 2016. The RTO will be manufactured at subsidiary SandMold Systems in Newaygo, Michigan with some specialty parts manufactured at CTP facilities in Austria.
