Selecting a separation technology often has more than one solution. The choice depends on the characteristics of the feed and the required outputs and other constraints linked to the type of plant and sector. The separation process also has its own constraints. Technologies can be used in stages, e.g. two or stages of the same technology or combinations of different technologies.
分離技術選用通常會有多項解決方案,至於如何選擇端視進料特性、產出要求及工廠及部門形式。
