Researchers observed desulfurication by sulfate-reducing bacteria in the contaminated estuary, which significantly lowered concentrations of oxidized inorganic sulfur compounds.

The refinery scheduled multiple desulfurications this quarter to meet new emissions standards.

While desulfurating the fuel, the engineer monitored sulfur emissions closely.

The refinery desulfurates crude oil before processing to meet environmental standards.

After several tests, the team desulfurated the crude oil to meet environmental regulations.

The refinery uses a catalytic process to desulfurate crude oil before transport.

The refinery invested heavily in new desulfuration units to meet stricter emissions standards.

Recent desulfurations at the plant lowered sulfur emissions and improved downstream catalyst performance.
