A self-cleaning process
Dr Clark is inspired by two examples from International Cement Review and Cemtech that demonstrate the potential for the cement kiln process to be modified to continuously clean itself of potential emissions, prompting thoughts of which other ways the process can or can be made to clean itself.
Smart plant design such as at St Marys Cement’s Bowmanville plant, Canada,
helps to reduce the environmental impact and costs of cement production
The inspiration for this month’s Technical Forum comes from two sources. Firstly, the article “Bowmanville’s lime hydration” as published in ICR’s August 2015 issue and first presented at the 2015 IEEE-IAS/PCA Cement Industry Conference in Toronto, Canada. Secondly, Scheuch’s ExMercury system as exhibited at Cemtech Europe 2015 in Vienna, Austria (see also ICR January 2016). What is so inspiring? Well, both involve modifying the cement kiln process such that it continuously self-cleans of troublesome emissions as part of the process. In the moderator’s opinion, this seems the best way to proceed and prompts the question: “In what other ways does the cement kiln process continuously self-clean?”
