Cement kiln mercury reduction strategies a case study in materials management

With the United States Environmental Protection Agency (EPA) drafting guidelines to control mercury emissions many in the Cement Industry are looking at opportunities to manage these emissions in a cost effective way. This paper summarizes three years of mercury management practice at Titan America´s kiln line in Florida. Topics include the operational practices that support a materials balance management protocol and the testing done to better identify the mercury cycle specific to the main dust collector. Finally a successful theoretical application of mercury management through dust disposal is summarized with estimates of the cost of application of such a system.
