Software has been put in place that optimizes the process of cement production. Over time, this software has been programmed to detect and react to process variations, while upholding all preset quality and operational conditions. The result has been a more consistent, higher quality product produced at ever-increasing efficiencies with lower environmental impact.
A major upgrade was initiated to the plant’s quality control system. The laboratory has been equipped with state-of-the-art analyzers, which can generate quick and accurate analysis of all material samples. In addition, cross belt analyzers were installed to analyze and control online the raw materials entering the process by conveyor. This improves the quality and the stability of the product.
In late 2007, the plant began to upgrade its main control system from the Honeywell platform, first installed in 1981, to the latest Siemens control platform. This upgrade has improved equipment controls to facilitate consistent operations.
The Permanente plant has always strived to incorporate the latest tools available to monitor and control its emissions. Numerous new fugitive dust capturing devices have been placed throughout the process, to further minimize its environmental impact. And to
further enhance and streamline reporting to all environmental agencies, the Continuous Emissions Monitoring system has been incorporated into the new plant control system and database.
