to desulfurize
- verb
- /dɪˈsʌlfəraɪz/
- Specialized
- To meet environmental regulations, we must desulfurize the coal used in our power plants.
Examples
-
Industrial coal-plant emissions are typically desulfurized by one of three methods: packed towers, tray towers, or spray towers.
Academic text (1996) -
They result in a synthetic gas that is cooled, making steam for electricity generation, and desulfurized before combustion in a turbine.
Academic text (1990) -
Some plants added desulfurizing scrubbers to their smokestacks or switched to low sulfur, coal and natural gas.
-
But the study also pointed to climate downsides: desulfurizing fuel would reduce the formation of cooling sulfate particles, which currently offset some global warming.

Although originally intended to desulfurize coal, the first catenary grid, 7 feet in diameter, was installed at the Nestle Foods coffee plant in Freehold, N.J., in 1982.
Academic text (1996) -
It would also reduce power consumption because, unlike spray towers, water only needs to be pressurized to about 5 pounds per square inch to wet the mesh and desulfurize the flue gas drawn through it.
Academic text (1996) -
The tray towers contain perforated metal trays onto which the limestone/water slurry is dispersed, so that flue gases passing through the perforations would be desulfurized.
Academic text (1996) -
Spray towers eliminate the clogging experienced by packed and tray towers by relying on erosion-resistant spray nozzles to create a droplet pattern that serves as the surface area needed to desulfurize flue gases.
Academic text (1996) -
The factory uses advanced technology to desulfurize the exhaust gases before they are released into the atmosphere.
-
Our new process efficiently desulfurizes the crude oil, making it cleaner and safer for the environment.
Synonyms
To remove dirt and bad chemicals from water or air to make them clean
Surface Forms
Morphology
desulfurize = sulfurize (transparent) = de + sulfur + ize
In technical vocabulary, 'de-' regularly signals removal, so 'desulfurize' is straightforwardly understood as removing sulfur from something.
Etymology
Desulfurize comes from the parts de- meaning 'remove' and sulfur, the element that often smells like rotten eggs. So to desulfurize is to take sulfur out of a substance, for example to make fuels and emissions cleaner.
