USPTO Application #: 20080213149
Title: Process for producing steam and/or power from oil residues
Abstract: Power is produced using fuel from raw and/or preprocessed oil residues which are burned alone, without any addition of sorbents, diluents or the like, to generate high pressure steam and/or power and residual emissions. Residual emissions are cleaned to simultaneously remove PM, NOX and SO2 therefrom. The sulfur in emissions can be used to produce sulfuric acid. The process uses a low cost fuel, generates steam, and/or power and sulfuric acid and meets all emission requirements for PM, NOX and SO2. (end of abstract)
