Evaporation of liquids with dispersant added
摘要:
A vertical tube evaporation process for the concentration of saline water and other liquids, including the addition of an anionic mono-molecular dispersant thereto which interacts with materials precipitated during concentration and inhibits the formation of scale or fouling depositions on evaporator surfaces, and wherein the additive is incorporated into the precipitated materials and improves their removal during the descaling or defouling of evaporator surfaces by rendering such precipitates redispersable in fresh water or in a non-saturated liquid used for descaling or defouling of evaporator surfaces.
