Is it technically feasible to lower the extraction temperature of the third-stage oil to produce light diesel? Is there any other teacher who can analyze, from a principled perspective, the effects on normal pressure and reduced pressure?
I’m not sure if there is a fourth stage beyond the third stage. If the pressure is reduced to produce lighter distillates, it will result in lighter products and residue, and the yield from atmospheric distillation will decrease; this seems to go against the principles of deep distillation in atmospheric and vacuum distillation systems. And this is also related to your factory’s diesel production process – do you not have any equipment for reducing the viscosity of diesel? Should we still use jet fuel for flights?
Ignoring the subsequent steps, it is feasible, but the device is a whole; one cannot consider only individual parts. If such an approach is taken, how should the top of the atmospheric pressure tower and the first stage of the process be operated? How can control at the bottom of the tower be ensured to guarantee the proper operation of the vacuum distillation tower and to maintain the quality and yield of the oils from various side streams in the vacuum process?
It is feasible, but the unit is integrated; the top of the atmospheric pressure tower and the distillation temperature in the normal line are low, which causes corrosion to the vapor line at the top
It can be extracted; the pull-out rate at atmospheric pressure decreases, the load on the vacuum furnace increases, and the load on the top of the vacuum tower also increases.
Personally, I think it’s better not to release it
