Independent Stack Emissions Improvement Study
As part of our Community Liaison Group and EPA endorsed Environmental Improvement Program (EIP), Adelaide Brighton Cement commissioned leading global cement industry technical experts, FLSmidth, to undertake a 'Stack Emission Improvement Study' of all its stack emission control equipment.
A final report with options to reduce stack emissions was submitted to the EPA for assessment and included the expected reduction in particulate emissions of each proposed option, and the projected site reduction in emissions under a series operational conditions.
A series of meetings and presentations were given to the EPA and the Community Liaison Group to communicate the details on the selected options for implementation, the methodology for the selection of the options for implementation and plant trials that were conducted to help validate the final options.
The revised compliance actions now include:
- A comprehensive upgrade of both the 4A Bypass and the 4A Gas Conditioning Towers (GCT) Spray Conditioning Systems, which is expected to significantly lower sitestack particulate emissions during operation. Relevant infrastructure was installed during the March 2017 annual shutdown, and the project is expected to be completed by October 2017.
- A comprehensive upgrade of the 4A Clinker Cooler Baghouse Controller and Particulate Detection System, which is expected to lower particle emissions from 4A tower. These improvements will enable bags to be immediately detected and isolated if not performing to standard. It will also allow for the continuous optimisation of the cleaning and monitoring cycles of the bags, which will minimise wear and is expected to lower particle emissions from the 4A tower stack. These projects were completed during the March 2017 annual shutdown.
