Currently, most distillation units use reduced-pressure deep extraction; let’s discuss the issues related to this method.

Process technology and equipment technology for vacuum deep drawing.
The reduced-pressure deep extraction technique involves raising the temperature further than the existing cutting temperature for heavy distillates, in order to increase the extraction rate of those distillates. The vacuum distillation unit is a fundamental device for the deep processing in refineries. By increasing the amount of wax oil obtained through vacuum distillation and reducing the amount of low-value residue, the value of the products can be further enhanced. The deep extraction capability of the vacuum distillation unit brings benefits not only to this unit itself, but more importantly to the catalytic cracking and coking units downstream, as well as to the overall efficiency of the entire refinery.
In fact, reduced-pressure deep drawing involves increasing the vacuum level in the vacuum tower as permitted by the temperature of the vacuum furnace, in order to extract all the oil that flows out of the tower. Increase the yield of distillate oil. Low-value residue or asphalt is obtained at the bottom of the tower. To serve as raw material for subsequent devices. But the properties of crude oil must be taken into account.

Everyone is doing deep pulling to reduce stress these days; it seems to be quite popular in recent years.
