At atmospheric pressure, reflux is used; what are the conditions for determining the tower top pressure and the yield of fusel oil?
Thread Content
When the process is stable, how can one determine the atmospheric pressure reflux, the top pressure of the tower, and the amount of fusel oil? How can distillation consumption be minimized? Can the increase in heavy components be controlled by the fusel oil recovery rate, the reflux rate, and the top pressure of the tower? But how can the optimal ratio be achieved? How to minimize consumption?
How do you usually control dry distillation? What are the typical control values for tower top pressure, reflux rate, and fusel oil recovery rate?
