Issues with blending crude oil at reduced pressure and vacuum levels
Thread Content
Our company’s atmospheric and vacuum distillation units process more than a dozen types of crude oil, including Russian crude, Saudi light crude, medium crude, heavy crude, Qatari onshore crude, Panyu crude, and condensate. Due to inventory issues, the blending of these crudes is highly uneven, which makes it difficult to operate the various distillation towers. At present, we use a blending method that involves processing the heavier crudes first and then the lighter ones, followed by mixing them using agitators. But the results are not good. I would like to ask all of you in this community: how do you carry out the blending of atmospheric and vacuum crude oils?
I recommend using an oil with a relatively high volume as the base oil, and then blending it with another type of oil; introducing it in a controlled amount into the crude oil pipeline can stabilize the properties of the crude oil
Actually, what I’m more concerned about is how to achieve effective uniform mixing.
