机械蒸汽再压缩分离处理
摘要：
这里揭示一种用于从含有污染物的流体进给流去除污染物的方法和设备。此方法包括提供进给流(10)和在第一步骤(18)中加热以至少部分去除某些污染物和从浓缩及馏出物生成回收能量的步骤。在一被加热的分离器中在第二加热步骤(20)进一步加热此进给流以生成饱和蒸汽馏分(30)和浓缩流体污染物馏分。蒸汽馏分可被压缩以生成此重沸器交换器中的温度差,此蒸汽馏分被传入与重沸器接触以从该重沸器提供凝结的蒸汽流。使此蒸汽流通过重沸器交换器和被加热分离器循环来维持该流中约1%至约50%质量的蒸汽。此设备包括有结合强制循环(42、44、38)回路的蒸汽压缩器、加热分离器的特定的结构来产生净化结果。
摘要（英）：

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.
