1. An apparatus for treating a wetted proppant, comprising:
a device to estimate a fraction of water in a wetted proppant feed of a frac proppant processing plant;
a system for determining an environmental temperature at which the wetted proppant will be exposed to in the frac proppant processing plant or in storage holding an output from the frac proppant processing plant; and
an additive system to apply a freezing point suppression additive to the wetted proppant having a water content of at least 0.25 wt %, in proportion to the fraction of water such that a mixture of the wetted proppant plus the freezing point suppression additive does not solidify at the environmental temperature.
