Could someone tell me the approximate composition and various parameters of the oil obtained by reducing it to first-line, second-line, third-line, and fourth-line levels? Which refineries sell these types of oils? What are the approximate prices respectively? Thank you
The oil from the pressure-reduction side stream is generally referred to as wax oil in refineries. It is the raw material for units such as catalytic cracking, heavy oil hydrogenation, and wax oil hydrogenation. Generally, large refineries do not supply products externally.
Affected by factors such as the properties of the crude oil and the temperature at the furnace outlet, the compositions of Line 1, Line 2, Line 3, and Line 4 for distillation also vary. It is recommended to do this separately each time the oil is changed. What we subtract here is the diesel fraction, which is diverted for delivery as diesel.
Lianxian oil is available from Shandong Luhua Petrochemical. We also purchase this type of raw material, but it’s for others; we don’t use it ourselves. We use secondary hydrogenation white oil instead.
The reduced-pressure line 1 has components similar to those of diesel; our plant’s control requirement is that the distillation temperature at 95% yield should not exceed 340 degrees. We use a lubricant-type reduced-pressure tower, and lines 2, 3, and 4 are primarily used to produce raw materials for lubricants, with quite strict control parameters in place for them.
We are of the fuel-type type; currently, the reduction is only by 95%, with a value not exceeding 367. It moves together with the normal level 3. Reductions of 2 or 3 generally result in a linear progression, while a reduction of 4 does not occur. When producing light oil, the residue carbon content needs to be controlled to stay between 17 and 25
Our factory has it: Line 1 is used to produce fuel oil, while Lines 2, 3, and 4 are used to produce wax oil or catalytic feedstock! Reducing by one level controls 90% of it; reducing by two, three, or four levels controls the pour point and sulfur content!
May I ask if, when the substance mentioned by the original poster is used as fuel oil and burned, the chimney will emit a light blue smoke?
