Consider SCR to mitigate NOx emissions

Integrated H2 production with a stationary gas turbine yields processing gases, steam and electricity while complying with stringent air-emission requirements of a nonattainment area

In this case history, a Gulf Coast refiner intended to upgrade its capability to convert heavy, sour crude oils into "clean" fuels. The refiner was able to: Secure a reliable, long-term hydrogen (H2) supply Integrate steam and electricity supplies with the expansion "Partner" with an industrial-gas supplier whose H2 plant complies with nitrogen oxides (NOx) and carbon monoxide (CO) emission limits in a moderate nonattainment area, as proven via stack testing and a continuous emissions monitoring system (CEMS).1 – 7 In this proactive project, the refiner outsourced the H2 supply to an "across-the-fence" steam-methane reforming (SMR) hydrogen plant integrated with gas-turbine techn
