July 6, 2023, Broken Arrow, Oklahoma ‐‐ Great Southern Flameless (GSF) announced today it has been awarded a commercial agreement with Southern Rock Energy Partners to design and supply furnaces and process heating units for a first‐of‐its‐kind crude refinery in Cushing, Oklahoma.   

While most refineries consume natural gas, refining off‐gases, and ambient air in the furnaces and process heating units, this proposed facility would instead combine pure oxygen with "blue" hydrogen (produced from refining off‐gases) and "green" hydrogen (from electrolysis), with water, oxygen, and argon being the primary waste stream. 

By  consuming  100%  hydrogen and  oxygen as a  fuel  source in  the  furnaces and  process  heating  units, Southern Rock Energy's proposed 250,000 bpd crude refinery complex will reduce and eliminate 95% of greenhouse  gas  emissions  (methane,  carbon  monoxide  and  dioxides,  and  nitrogen  and  sulfur  oxides) utilizing GSF  Cool  Combustion Technology while  still  producing approximately  91.25 million  barrels  or 3.8325 billion gallons annually of cleaner transportation fuels including gasoline, diesel, and jet fuel from crudes sourced domestically from the Anadarko, Denver‐Julesburg, Permian, and Bakken Basins.
