Calculation of atmospheric and vacuum distillation yields
Thread Content
Please share how you calculate the baseline yield for your atmospheric and vacuum distillation units; ours is calculated using the content at 330 degrees after dehydration as the reference point
Reply to 1# Trace elements: Separate light yield and total yield; the yield from gas coal and firewood is counted as part of the light yield, while all other yields are considered part of the total yield, excluding residue oil
Is ours calculated based on the 330-degree content after degassing? What does that mean? Yield refers to light yield and total extraction; it is the ratio of their output to that of the raw material.
We exclude the normal slag and any excess slag; what remains is considered the yield
What the original poster is referring to is the baseline yield, which is determined based on data obtained from distilling crude oil at its actual boiling point; oils with a temperature below 330 degrees are considered the products obtained from this process… Around 330 degrees, it’s mainly wax oil components. What is the distillation range distribution of your crude oil? In my opinion, the temperature should be increased, including the boiling range of the paraffin oil, so as to reflect the characteristics of the crude oil, as well as the goals and potential of the atmospheric and vacuum distillation units…
We also consider those with a true boiling point below 330 to be lightly condensed. It is not considered a normal fourth-grade product, as normal fourth-grade products contain more wax oil, which is used directly as feedstock for wax production or as sealing oil.
Oils with a viscosity below 330 are used as the final products; normal residue is removed, as well as reduced residue, and wax oil is not included either.
