ABSTRACT:
The present invention relates to transportable product for the transportation of paraffinic wax and methods of transporting using this transportable product. The transportable product comprises 90 to 20 weight % of a liquid comprising ≧50 weight % water and having a pH of >5 and a true vapor pressure of ≦14.7 psia when measured at 20° C., and 10 to 80 weight % of wax particles, wherein the wax particles comprise ≧75 weight % of wax particles larger than 0.1 mm. The transportable product and methods of transporting according to the present invention are able to accommodate a relatively high weight % of paraffinic wax particles in the transportable product while avoiding interparticle adhesion and clumping by ensuring that the wax particles are not too small and the amount of small wax particles is not excessive.
