摘要： A method for solution crystallization of mixtures of substances includes: providing a liquid mixture of substances including at least one component substance having an elevated melting point; drawing off a substream from the mixture of substances; feeding the substream to a heat exchanger so that the substream flows through the heat exchanger; cooling the substream in the heat exchanger to a temperature below a crystallization temperature of only the at least one component substance so that crystals from the at least one component substance form in the substream at an outlet of the heat exchanger; blending the substream including the crystals into the mixture of substances so that the crystals in the mixture of substances selectively bind other substances as a result of crystal growth; and providing for sedimentation and precipitation of the crystals in the mixture of substances.
