The significance of several indicators in hydrogenation units

What does the bromine number mean in refined diesel? What is the relationship between copper corrosion and total sulfur content? In the specifications of refined aviation fuel products, what does color represent?
The higher the bromine value, the higher the content of unsaturated hydrocarbons in the oil.
The bromine value represents the ability of diesel to undergo addition reactions with bromine, that is, the number of unsaturated bonds； In my opinion, the higher the sulfur content, the greater the copper corrosion
The bromine value is primarily determined by the content of olefins, while color is related to stability.
The bromine value indicates the amount of unsaturated olefins, while copper corrosion is related to the levels of thiolic sulfur and hydrogen sulfide, not to total sulfur. Chroma is used to assess the stability of aviation fuel.
The higher the content of unsaturated hydrocarbons in the oil, the higher its bromine value; copper corrosion is related to active sulfides, which are part of the total sulfur content.
The bromine value is high, and the olefin content in the oil is high. The copper corrosion test failed; it is necessary to check whether the product still contains hydrogen sulfide. The operation of the downstream stripping tower can be adjusted, and it is also important to examine the heat exchangers used for the product and raw materials to determine if there are any leaks. Chroma refers to stability.
