Environmental challenges at Cemex-Davenport, CA

摘要

Cemex's plant at Davenport, CA (FIGURE 1) has faced a number of environmental and operational challenges in its day to day operation. This includes compliance with strict gaseous and particulate emissions regulations, and the market requirement to produce a low alkali cement product. Many of these challenges are dependent on the pyroprocessing system operation and steps taken to optimize one challenge can often have an impact on a separate challenge. This paper document these specific challenges that have been faced and the solutions that have been taken. Beyond the challenges already faced, the Davenport plant continues to look ahead to continue optimizing the operation and handle any possible challenges for the future.
