Application of Advanced 2-D TDLAS diagnostics for the Optimization of Combustion in Steam Methane Reformers

Paper from the AFRC 2013 conference titled Application of Advanced 2-D TDLAS diagnostics for the Optimization of Combustion in Steam Methane Reformers by Andrew Sappey.

We present results from two separate demonstration installations of the ZoloBOSS TDLAS sensor system on Steam Methane Reformers. The ZoloBOSS provides two-dimensional information on temperature and species concentration distributions (O2, CO, and H2O) inside the operating SMR furnace. This unique data set allows the operator to balance the temperature distribution in the furnace as well as insuring that the desired distribution of O2 and fuel is realized. The value of such a system for operating SMRs includes contributions from improved efficiency, longer tube life, increased catalyst life, reduced emissions, remote monitoring, and safety. Results at both nominally well-run plants indicate that: 1) significant combustion profile imbalances were initially present in both furnaces upon installation, 2) the data provided by the ZoloBOSS can be used to improve balance by manually tuning burners, and 3) significant ROI will be realized as a result of long-term implementation and optimization.
