Abstract
The invention is a process for producing a mixture of wax and crude oil which can be pumped at ambient temperature. The wax is preferably a Fisher-Tropsch wax. The temperature of the crude oil is controlled to a level below the dissolution temperature of the wax. The wax crystals are homogenized and dispersed into the crude oil to form a mixture. The present invention prevents the wax from dissolving in the crude oil and subsequently re-crystallizing at lower temperatures which can substantially increase the viscosity of the mixture thereby decreasing the effectiveness of transporting the mixture.
