Summary. TRI’s steam reformer technology for carbonaceous feedstocks such as woody biomass, agricultural waste, Municipal Solid Waste (MSW), black liquor, waste sludge, and young coals is characterized by indirect heating and deep bed fluidization in the bubbling regime. TRI has been actively working with CPFD since 2008 to model the steam reformer and validate the resulting Barracuda Virtual Reactor simulations. Many studies have been performed including cold flow of single and multiple particle species, tube bundle representation, liquor injection, thermal and homogeneous/heterogeneous reaction modeling, solids mixing/segregation/entrainment, several different feedstocks, multiple reactor scales (laboratory to commercial) and first- and second-generation heater modes. Experimental and modeling insights have enhanced the accuracy of predictions, while advances in both software and hardware have significantly reduced the total run time for quasi-steady convergence. Selected results from these studies are presented.
About the speaker. Ravi has been on a quest to “minimize the increase in entropy” ever since he read the Feynman Lectures on Physics. Ravi is with TRI and leads technology development, scaleup and process modeling and is responsible for intellectual property. Previously, he was the Vice President of Engineering at Manufacturing and Technology Conversion International, Inc., Baltimore, Maryland and prior to that was Research Specialist at Babcock & Wilcox’s R&D Division in Alliance, Ohio.
