ABSTRACT:
A method and composition for control of in-transit and residual dust, erosion, and wetting of coal or coke feeds is provided. The method involves spraying the coal or coke with a solution comprising a fluid, preferably water, containing a sufficient amount of an additive comprising (a) approximately 90-99 wt % of a binder, preferably a lignosulfonate, a polyether, a polyol, or a byproduct produced during the refining of a natural sugar, and (b) 1-10 wt % of a polyacrylate, a polyvinylalcohol, or a polyacrylamide. The additive also preferably contains a surfactant. The amount of solution/additive that is necessary will vary according to the desired result and the conditions to which the coke or coal will be subjected.
