Extraction distillation calculation
Thread Content
When performing calculations, what rules does the system use by default for LIQUID1 and LIQUID2? For example, in the PROII example MEK-WATER-TOLUENE, specification 1 specifies that the reflux rate of LIQUID1 is 0. Here, LIQUID1 should be the aqueous phase, right? 》
Or, after stratification, based on density – the layer with lower density at the top is LIQUID1, and the layer with higher density at the bottom is LIQUID2? Last edited in this post by rita_*ao on 2009-2-13 17:32]
The upper layer with lower density is LIQUID1, and the lower layer with higher density is LIQUID2
Based on density, the upper layer with lower density is LIQUID1, and the lower layer with higher density is LIQUID2. In typical top condensers, it is specified that the aqueous phase be completely removed while the material phase is recycled, such as in the isopropyl ether-water system.
