ADVANCED OXYFUEL BOILERS AND PROCESS HEATERS FOR COST EFFECTIVE CO2 CAPTURE AND SEQUESTRATION
This annual technical progress report summarizes the work accomplished during the second year of the program, January-December 2003, in the following task areas: Task 1--Conceptual Design, Task 2--Laboratory Scale Evaluations, Task 3--OTM Development, Task 4--Economic Evaluation and Commercialization Planning and Task 5--Program Management. The program has experienced significant delays due to several factors. The budget has also been significantly under spent. Based on recent technical successes and confirmation of process economics, significant future progress is expected. Concepts for integrating Oxygen Transport Membranes (OTMs) into boilers and process heaters to facilitate oxy-fuel combustion have been investigated. OTM reactor combustion testing was delayed to insufficient reliability of the earlier OTM materials. Substantial improvements to reliability have been identified and testing will recommence early in 2004. Promising OTM material compositions and OTM architectures have been identified that improve the reliability of the ceramic elements. Economic evaluation continued. Information was acquired that quantified the attractiveness of the advanced oxygen-fired boiler. CO{sub 2} capture and compression are still estimated to be much less than $10/ton CO{sub 2}.
