Abstract
A system for manufacturing a pigment comprising an oxidation reactor capable of providing a pigment, a scouring media source, and a heat exchanger having a tubular conduit through which the mixture of the pigment and the scouring media flows. The tubular conduit having an inlet, an outlet, and a longitudinal center line. The tubular conduit configured such that at least a portion of the longitudinal center line of the tubular conduit extends in a helical pattern.
Claims11
A system for manufacturing a pigment, the system comprising:
- an oxidation reactor for of providing a pigment;
- a scouring media source capable of providing a scouring media;
- a heat exchanger in fluid communication with the oxidation reactor and the scouring media source so as to receive a mixture of the pigment and the scouring media, the heat exchanger comprising:
- a tubular conduit through which the mixture of the pigment and the scouring media flows, the tubular conduit having an inlet, an outlet, and a longitudinal center line, the tubular conduit being configured such that at least a portion of the longitudinal center line of the tubular conduit extends in a helical pattern;
- and
- means for cooling at least a portion of the tubular conduit;
- and
- a filter positioned to receive the mixture of the pigment and the scouring media from the outlet of the tubular conduit, the filter capable of separating the pigment from the scouring media.
