  • Method to produce cement clinker using high sulfur content fuel
    Patent number: 6599123
    Abstract: This describes a method for producing cement clinker using petroleum coke with a sulfur content over 4.5% by weight, in conventional equipment and facilities, wherein said method comprises the treatment of the raw mixture to synergistically improve its physical-chemical characteristics combined with the parameter control of the process, in such a way as to obtain a reduction of the clinkering temperature, all as a heretofore-unappreciated way to reduce, as a result, the concentration of SO3 in the calcinated material fed to the rotating kiln, and also usefully increasing with this the calcium sulfate content in the clinker.
    Type: Grant
    Filed: July 13, 2002
