CHAPTER Energy Considerations in Distillation 6

Distillation processes involve mass transfer between a liquid phase (or two liquid phases) and a vapor phase flowing in countercurrent fashion. The vapor and liquid ... 350 C; these fluids in turn require heating by a high-temperature heat source such as a fired heater, as shown in Figure 6.3. Using heat transfer fluids, pumped

Why does the temperature drop after the first component is ...

Feb 12, 2009 · I have to do a writeup for a lab. The whole question goes like this: "When running a fractional distillation, you may observe that the temperature suddenly drops after the first component is distilled. Explain this observation." This is a hypothetical question, not related to the components I actually distilled. I know that the effect could be boiling point depression because there are 2 ...

8.9: Distillation - Chemistry LibreTexts

Distillation is a process whereby a mixture of liquids having different vapor pressures is separated into its components. At first one might think that this would be quite simple: if you have a solution consisting of liquid A that boils at 50°C and liquid B with a boiling point of 90°C, all that would be necessary would be to heat the mixture to some temperature between these two values ...

Distillation - Wikipedia

Like vacuum distillation, steam distillation is a method for distilling compounds which are heat-sensitive. The temperature of the steam is easier to control than the surface of a heating element, and allows a high rate of heat transfer without heating at a very high temperature. This process involves bubbling steam through a heated mixture of ...
