Primary side line to normal line external delivery
Thread Content
What is the reason for sending the oil from the primary side line of the initial distillation tower to outside the normal distillation line? The normal feed line is used for diesel hydrogenation.
What is the purpose of the initial distillation tower, and what components are there? What’s your status? You haven’t said anything, so we can’t guess
Generally, side streams are rarely produced from a primary distillation tower; it’s usually just the light ends oil! ! ! !
The distillation profile of the primary side line is quite similar to that of the normal side line, allowing it to be directly used as a product and sent for hydrogenation treatment.
We use primary side oil in the constant-pressure column at Changzhong No.1
As it is an old facility, the components used in processing crude oil at the time of its design have changed significantly. Of course, if the oil from the primary side and the components from the normal fractionation line are roughly similar, it is possible to feed the oil directly into the normal fractionation line. After all, industrial production is aimed at generating profits, and this approach can help reduce energy consumption to some extent
