The COBRA process is an advanced embodiment of the chemically well proven copper oxide process. COBRA stands for Copper Oxide Bed Regenerative Adsorber, a moving bed - cross flow configuration which is ideally suited for SO{sub 2} control and NO{sub x}, reduction through its SCR capabilities. The moving bed adsorber provides low sorbent attrition and allows the use of larger sorbent particle sizes for an overall more economical design. The location of the COBRA process between the economizer and the air heater enhances low temperature heat recovery by removing SO{sub 3} in addition to SO{sub 2}, thereby allowing for very low flue gas temperatures. This paper presents the results of a sensitivity analysis aimed at optimizing the design of a 400 Mw system and integration into a low emissions boiler system. It will identify the benefits of the technology, showing how it is possible to achieve a 99% reduction of SO{sub 2} with very low power consumption and produce a salable by-product - either sulfuric acid or elemental sulfur.
