Basis for fractionation and cutting
Thread Content
During the distillation process, the extraction temperature serves as the main criterion and an intuitive parameter for separating different fractions. Why is that? I would also like to ask fellow experts about the application of the three key balances in distillation control
I play with air \"fractionation,\" but the principle should be the same. I don’t want to discuss the essence of the problem; I just want to talk about the learning approaches, which might be helpful for you in solving it. For chemical plant systems, it is best to start with the principles of the process flow, then move on to the principles of individual equipment, and finally to the principles behind setting process conditions. Finally, it is combined with the actual operational control at the control site. I think for some theoretical, highly specialized, or some irregular rural dialects,,, It’s best to master the basics first, and then gradually delve deeper. However, the deeper approach should focus on daily maintenance of the equipment, mechanical repairs, and the automatic control of electrical interlocks related to the instruments. As for the static equipment of the type devices, that is the designer’s responsibility. As an on-site operator, it’s sufficient to do one’s job well. Finally, I recommend the basic reference book \"Principles of Chemical Engineering\".
Based on the bubble point temperature of the oil, and after a reference temperature is determined, operation at that temperature range for more than 4 hours is carried out to properly replace the side stream. Samples are taken, and the product is adjusted based on those samples; the product is ready in less than 8 hours, but the quantity is very small. The flow rate can be adjusted within 24 and -48 hours
The process flow diagram includes the relevant principles. Flowcharts are the language of positions, and everything must be built on this foundation. Very eager to learn.
Then if you’re not checking the extraction temperature, what are you checking? Check the pressure?
During the distillation process, the extraction temperature serves as the main criterion and an intuitive parameter for separating different fractions. Where did I learn that? Is the extraction temperature indeed the main criterion and intuitive parameter for separating fractions? Why not the vapor temperature of the tray below the layer from which extraction takes place?
