Heat and Mass Transfer: System Analysis of Process Burners

Abstract

A petroleum refinery in Louisiana reduced the NOx levels at its new coker unit by retrofitting several crude heaters with ultra-low NOx burners. The refinery encountered a number of problems in retrofitting the burners for NOx reduction such as burner-to-burner and burner-to-furnace interactions. Computational fluid dynamics (CFD) and cold-flow physical modeling were successfully used to troubleshoot and solve potential problems with ultra-low NOx burner retrofits. The modification of the crude heaters, pre-installation modeling, preliminary troubleshooting, parametric CFD analysis, and the results of field implementation of the modified burners are discussed.
