COPE (Claus Oxygen-based Process Expansion) technology presents an improvement to the modified Claus process that replaces air with up to 100% oxygen to debottleneck Claus Sulphur Recovery Unit's (SRU's). The major equipment requirements of the COPE process are the installation of an acid gas recycle blower and a proprietary burner. The recycle stream acts as a coolant to moderate reaction furnace temperature, effectively replacing nitrogen as a diluent. The specially designed burner allows for the safe and effective handling of the four feed streams: air, oxygen, acid gas, and recycle gas. Co-licensed by Goar, Arrington and Associates, Inc. (GAA) and Air Products and Chemicals, Inc., the COPE process presents an economically attractive means of expanding the capacity of an SRU. The first two COPE units are in commercial operation at a major gulf Coast refinery in the USA and have demonstrated an 85% increase in capacity by enriching to the 55% O/sub 2/ level.
