Latest Patents
Harry S Tang holds a patent for a method of removing NH₃ and HCN from an FCC regenerator off gas. This innovative method involves the addition of an oxygen-containing gas under specific process conditions to an off-gas stream derived from an FCC regenerator operated in a partial mode of combustion. The off-gas from the regenerator contains 1-6% CO by volume and at least 300 ppm nitrogen compounds, including NH₃ and HCN. Without the addition of an oxygen-containing gas, approximately 25 percent of the NH₃ and HCN are converted to NOₓ in downstream CO boilers. The preferred method of this invention includes the addition of heated air (20% O₂) into the regenerator off gas, resulting in an off gas stream with a temperature range of 1260°F to 1500°F.
