    摘要: The deposition of calcium salts, including calcium carbonate and calcium oxalate and the formation of foam, during the evaporation of sugar streams can be prevented or restricted by adding 0.1 - 200 ppm of a carboxyalkylfructan that contains 0.5 - 3 carboxyl groups per monosaccharide unit, 0.4 - 2.5 of which carboxyl groups are in the form of carboxyalkyl groups, to the sugar streams. The carboxyalkyl groups are, in particular, carboxymethyl groups. The other carboxyl groups can be carboxyl groups obtained by oxidation. The carboxymethylfructan gives comparable results to polyacrylates, which are less desirable from the standpoint of health and the environment.

    摘要: A method and apparatus for removing a contaminant from a fluid feed stream containing the contaminant. The method includes the steps of providing a feed stream (10) and heating it in a first step (18) to at least partially remove some of the contaminants and recover energy from a concentrate and distillate generated. Further heating the feed stream in a second heating step (20) in a heated separator generates a saturated vapor fraction (30) and a concentrated liquid contaminant fraction. The vapor fraction (30) may be compressed (32) to generate a temperature differential in the reboiler exchanger (34) with the vapor fraction being passed into contact with a reboiler exchanger (34) to provide a stream of condensed vapor from the reboiler. The stream may be circulated through the reboiler exchanger (34) and the heated separator to maintain from about 1% to about 50% by mass vapor in the stream. The apparatus includes a unique configuration of a vapor compressor, heated separator in combination with a forced circulation (42,44,38) circuit to generate the decontamination result.
