Abstract: PROBLEM TO BE SOLVED: To provide a method of producing ice in water slurry where the dispersion of ice particles is assured to be sufficient and the flow resistance is reduced without corrosion of a transporting pipe system, and to provide a transporting method with a reduced power through a transporting pipe system. SOLUTION: A mixture of heating-media prepared by incorporating water where solbitol as a forming aid for the ice in water slurry is added, and an amphoteric surfactant as a dispersant of the ice in water slurry is cooled to the freezing point or below. Successively, the mixture is released from excess cooling to form the ice in water slurry where ice particles are disperesed. By this procedure, the ice in water slurry having effects of reduced flow resistance, good dispersion of ice particles and no corrosion problem is prepared. COPYRIGHT: (C)2003,JPO

Abstract: PROBLEM TO BE SOLVED: To transport slurry without additive in normal operation, and adding the additive (stabilizer, dispersant) previously prepared in the slurry in a pipeline by a supply means at a time of a shutdown to prevent settlement of solid particles until restart. SOLUTION: Settling slurry is transported by a force-feed pump 3 through the pipeline 2. Additive supplying means T1, T2, T3 for supplying the stabilizer for suppressing the settlement of the solid particles and the dispersant for reducing viscosity of the slurry to the settling slurry transported through the pipeline are provided in a site of the force-feed pump 3. The stabilizer and dispersant are supplied in the pipeline 2 by the additive supply means just before the pipeline transportation is stopped, the supply of the additive is continued until the stabilizer and dispersant are spread uniformly in a total area of the pipeline 2, and the supply is stopped after spread.
