Azeotropic vapor at the top of the column. Immiscible Liquids In figure (a), boiling starts when . In figure (b), boiling starts when or . This is the principle of steam distillation. I have some questions regarding the concept of steam distillation: The textbook introduces the equation with...
The process achieves very low temperatures and, therefore, liquefies a substantial portion of the ethane and heavier compounds in natural gas. The various fractions of the liquid stream are recovered by distillation. The turbo-expander process configurations can vary greatly. They all incorporate ...
Next, atmospheric distillation is used to obtain light gases, gas oil, and a heavy product. The heavy product is distilled under vacuum to yield lube oil. Both the gas oil and the lube oil should be further processed to attain desired properties. The gas oil is steam stripped to remove ...

Process flow diagrams of open art process units like CDU (Crude distillation unit), and VDU (vacuum distillation unit) can be found in the literature and encyclopedia of chemical technology. Some of them may be obsolete. After that, the PFD is reviewed by the engineering contractor’s process...
unit operations such as mixers, separators, reactors, distillation columns and heat exchangers are usually denoted by a simple block or rectangle groups of unit operations may be noted by a single block or rectangle process flow streams flowing into and out of the blocks are represented by neatly...
The industrial process adopted by the distilleries consists of fermenting the diluted molasses with yeast and distilling the alcohol produced in distillation columns by passing a counter current of steam while allowing the fermented mash to come down the tall column. Only about 10 per cent of the ...
It is separated by distillation and leaves from the bottom of the tower. In this case, a temperature and pressure flag would be provided for the stream leaving the reboiler. Example 1.6. In the benzene process, the feed to the reactor is substantially hotter than the rest of the process ...

I have some questions regarding the concept of steam distillation: The textbook introduces the equation without much quantitative analysis, only mentioning that the two solutions are mutually saturated. What role does saturation play here? Pressure is an intensive quantity; why can it be directly adde...
