Description:
This Phase II SBIR proposal presents a concept for a chemical monitor based on differential catalytic reactivities and heterogeneous reaction exothermicities. The simplicity of the proposed sensor concept promises an economical and reliable monitor for continuous, in-situ measurements of a variety of gases. Envirochem proposes to continue development of this concept for measuring ammonia in flue gases. A sensitive, in-situ, real-time ammonia monitor is required for control of many NOx control processes that either use or produce ammonia.The goal of the Phase II project is to develop a prototype instrument with sufficient sensitivity, selectivity, and linearity to test as a process control monitor. An instrument employing the most promising catalyst wires will be tested for longevity and poisoning by likely contaminants. A prototype commercial system will be tested over a broad range of parameters and compared with other monitors in real environments.
