How should quality control and adjustment of products be carried out? I searched on the forum but didn’t find a comprehensive answer. I hope fellow users will actively discuss this and provide a more thorough response.

The topic is quite large. What are the main products of atmospheric and vacuum distillation units? Answer: The main products include naphtha, kerosene, aviation kerosene, diesel, vacuum residue, and marine fuel. How should quality control and adjustment of these products be carried out? Answer: It is mainly adjusted by controlling the outlet temperature of the heater, the reflux volume, the amount of material discharged externally, and other parameters, based on changes in the quality of the crude oil.
Military diesel, 200# solvent oil, regular diesel, aviation kerosene, gasoline, etc
The main products are as follows: 1. Light gasoline (naphtha); 2. Light oil No. 1 and Light oil No. 2 (diesel); 3. Heavy oil No. 3, Reduced oil No. 1, Reduced oil No. 2, Reduced oil No. 3 (wax oil); 4. Residue oil; 5. Gas oil. Product control and adjustment are quite simple: reflux is used at the intermediate stage to control the outlet temperature, and samples are taken at the delivery point for testing. For example, to control the 95% fraction of Light oil No. 1, reflux is utilized to regulate its outlet temperature, while it is also important to prevent large fluctuations in the temperature of Light oil No. 2. The flash point of Light oil No. 1 is controlled by the stripping process in the stripper; one can adjust it according to the desired level of flash point. I won’t go into too much detail here as typing is tedious – this experience is quite important; it’s the supervisors who set the targets, and we just need to ensure that the products meet those standards while achieving the highest possible yield.
The main products include straight-run naphtha, regular diesel, vacuum wax oil, and vacuum residue; the final boiling point of naphtha can be controlled by adjusting the tower top temperature； Tsugami can control its boiling range by adjusting the distillation temperature at the atmospheric pressure side stream, and the flash point of the product can be controlled using stripping steam in a stripper ； For reduced-pressure wax oil, we control the distillate volume at 350 degrees and 500 degrees ； Control the distillate volume of vacuum residue before 500 degrees ； This is my personal understanding, for reference only; let’s learn from each other*.

The main types are: gasoline, diesel, residue, and reduced residue. The adjustments are made to the initial boiling point, final boiling point, dry point, octane rating, etc., depending on the product you need
The topic is too broad; here are a few books to study it: \"Petroleum Processing Technology,\" \"Series on Technical Knowledge in the Oil Refining Industry – Crude Oil Distillation,\" \"Petroleum Refining Engineering,\" and so on. Reading these should be sufficient
The main products are naphtha, diesel, wax oil, and residue. Control and adjust the furnace temperature, introduce steam at the bottom of the tower; increasing the pressure at the top of the atmospheric tower and the vacuum level at the top of the vacuum tower improves the gasification rate of the oil products as well as the separation accuracy
