What method can be used instead of real boiling point distillation?
Thread Content
Since the real boiling point distillation device is too expensive (hundreds of thousands), the teacher cannot buy it. But if I want to determine the distillation range of shale oil, what method can be used instead of real boiling point distillation, and the error is relatively small? Since shale oil decomposes when it reaches a certain temperature, vacuum distillation must be used. The question is, how can the conversion between normal pressure and reduced pressure be achieved?
You can do Engler's distillation and then convert it into a real boiling point distillation curve according to the conversion method. Please refer to the textbook for the specific conversion method.
Engler's distillation can only be used in the normal pressure distillation range. When it reaches a certain temperature, if the normal pressure distillation is continued, the shale oil will react because it contains a large amount of unsaturated hydrocarbons.
Is it possible to use software to make the previous data, and use chemical engineering software such as PROII or Aspen to calculate the subsequent data? The error may be larger.
What kind of school is this if it doesn’t even have this? There should be one in the chemical engineering department.
You can also perform reduced pressure Engler's distillation. After that, convert it to normal pressure.
There are regulations for using that thing. I can’t say whether it’s a national standard or not, but if you use it for other people, it doesn’t seem to be recognized! ! The money you should spend must be spent, and you can’t save it!
