The Reduced Emission Oxygen Kiln

We are pleased to submit our white paper report on the Reduced Emission Oxygen (REO) kiln. The document outlines the basic technology and the operational differences between the REO kiln and a conventional cement plant. We trust that you will find the results as exciting as we do and look forward moving this next generation cement technology to market. The REO kiln represents a paradigm shift in cement production that aims to capture virtually all greenhouse gas emissions from the facility while increasing production and energy efficiency. The process will consume more electrical energy, for oxygen production and carbon dioxide compression, but we anticipate significant reductions in category pollutants such as acid gases and particulates. We thank you for your support in this endeavor and look forward to future collaborations. Please do not hesitate to contact us if we may be of further assistance. The cement industry is challenged with developing methods for reducing anthropogenic emissions of carbon dioxide to the atmosphere at a cost that does not suffocate growth. While some technologies can be retrofitted to existing plants, we look forward to the next generation of cement plant that improve efficiency while significantly reducing emissions of greenhouse gases and other category pollutants. Such a facility could be based on oxygen combustion and would represent a paradigm shift from existing technology. The objective of this report is to propose a roadmap for this next generation plant and to highlight potential areas of future research. We do not presume to think that we have identified every opportunity and challenge associated with these plants. Furthermore, we welcome comments and constructive criticism, and believe that the scientific and cement community can move forward together in a cooperative and productive manner. We recognize that issues related to competition among cement companies may limit information sharing but hope that we can help encourage as much cooperation as possible. There will certainly be much experimental and design work prior to the implementation of any such technology and we look forward to participating in collaborations that make real progress towards a sustainable future for cement producers worldwide.
