Project Objective: The primary goal of this project will be to examine the possible development of protective coatings for the interior of process equipment and pipelines handling dSCCO2. There is some indication that handling of dSCCO2 may introduce here-to-for unanticipated corrosion in standard processing equipment and pipeline materials used for clean SCCO2.
Project Description: This is a proposed study of specialty coatings development for use in co-sequestration processes and pipeline transport of dirty Supercritical CO2 (dSCCO2) fluids. Test methods appropriate to such property characterization under such conditions will be developed and extended to use with the NDSU Combinatorial Materials Science development laboratory. Synthesis and testing of polymers for physical properties appropriate to process and pipeline use in the co-sequestration system will be the preliminary task, then pigmentation of the candidate polymers for proper physical performance. Consideration will be given to appropriate exterior coatings systems as well as implantation of sensors within the coating systems.
Potential Impacts In lieu of being totally dependent on very expensive specialty steels for proper handling of dSCCO2, we are proposing the examination of the extension of protective coatings technology to possibly allow the use of more standard low cost process materials and pipeline steels. As the co-sequestration process matures and becomes a candidate for possible of large scale use for greenhouse gas control, providing the option for use of protective coatings for system safety and health and well as cost control may become very important.
