Modular continuous processes are the future of chemical process development and chemical manufacturing. They enable faster time to market, improved safety, lower costs, and enhanced flexibility over traditional batch processes. Proposed work under this topic includes the design of a modular system for synthesis of many energetic materials, energetic precursors, and critical chemicals. Modules that are proposed for use in this platform include reactor technologies such as plug flow reactors (PFRs), microfluidic reactors (e.g. AFRs), continuous stirred tank reactors (CSTRs), electrochemical and photochemical reactors, batch/semi-batch/semi-continuous reactors, pumping and pressure transfer modules, solid feeders and work-up modules such as liquid/liquid separators, continuous oscillatory baffled crystallizers, continuous filters (e.g. belt filters or centrifuges). Support of the module design will include research into modern, continuous electrochemical routes for synthesis of energetic materials and critical chemicals. Module design under the Phase I Base will include process flow diagrams (PFDs), engineering calculations, scale-up design, and cost analyses. Module design under Phase I Option will include fabrication of process and instrumentation diagrams (P&IDs) as well as Computer Aided Design (CAD) drawings. A future Phase II effort would consist of fabrication and demonstration of the modular system for synthesis of target materials of interest.
