Study of Ammonia Source at a Portland Cement Production Plant (Journal Version)

摘要

A source and process sampling study was conducted at a dry process Portland Cement production plant. One aspect of the study focused on the source or point of NH3 within the production process. An extensive number of process solids from raw feeds to baghouse solids were collected and analyzed for NH4(1+). The results show the presence of NH4(1+) in many process samples, and that its collection efficiency in the baghouse is related to baghouse temperature. The data also show that NH3 is derived from the shale used in the raw feed at this cement production plant.
