Kiln Ring and Buildup Control

+ Combustion Improvement

EES HM-910 Sulfur Control Agent is a specialized additive for the cement industry formulated as a high reactivity suspension enhanced with stabilizers and surfactants. EES HM-910 Sulfur Control Agent inhibits the catalytic action of vanadium compounds found in residual fuels rich in sulfur, such as fuel oil and petcoke.


Due to the inhibition properties of EES HM-910 Sulfur Control Agent, during combustion some specific reactions are modified to form a fragile and high melting point crust and rings allowing for an easy removal by the process itself and/or cleaning procedures.

EES HM-910 Sulfur Control Agent is an effective option for sulfur control associated to build-up problems at pre-calciners and pre-heaters in the cement process. Also, EES HM-910 Sulfur Control Agent avoids ring formation at rotary kilns.

When vanadium is “deactivated” by the HM-910 additive, its catalytic effect for the oxidation of SO2 to SO3 gas is eliminated, therefore the oxygen that would be spent for this reaction remains available for combustion. This allows for a more efficient combustion, consequently the thermal consumption lowers significantly
