Hydrosulphurization method

• Effective method of desulphurizing coal and oil fuels.
• This method treats fuels in the presence of hydrogen at high pressure and temperature.
• Finely grounded coal is mixed with anthracene oil along with hydrogen to produce slurry.
• The dissolved coal is passed through a pressure filtration unit in which pyretic sulphur is removed.
• A flash evaporator is used to convert the dissolved coal to low sulphur coal.
