Hello Everybody

We are interested to know what specifications can be used to evaluate the efficiency of the chemical additive for the dust supression wet spray system for petcoke stockpiles. Some years ago we try to make tests on the real stockpiles but the atmosferical conditions do not allow the same conditions for all the test period. Actually we are looking for laboratory tests (measurement of variables) associated to the efficiency of this chemicals e.g. density, surface tension, wetability, etc. ¿what are the most important variables to measure? ¿what could be the metods to determine it? and ¿What's the target for any of this variables?

Thanks a lot. ■
