ABSTRACT:
An asphaltene concentrate characterized by its high softening point and by its high viscosity when in the liquid state is rendered into a pumpable form at ambient temperatures by conducting the asphaltene concentrate in liquid state directly from the precipitation zone at a high temperature, or from an intermediate heating zone wherein it attains a sufficiently high temperature, into a moving stream of water, whereupon the asphaltene concentrate immediately solidifies into lumpy or string-like particles. These particles are mixed with water and the mixture is subjected to a grinding operation which converts it to a thick suspension or semipaste which is thixotropic in nature and exhibits an apparent low viscosity at ambient temperatures, making it readily pumpable.
