Utilization of alkaline nitrogen generated during furfural complex denitrification of lubricating oil base oil?
Thread Content
In order to improve the oxidative stability of the lubricating base oil, it is necessary to modify it. The most common one is to adopt complex denitrification technology. This technology is based on the Lewis acid-base theory. Basic nitrogen has lone pairs of electrons and can coordinate with metal ions and protons with empty electron orbits in the outer layer to form complexes that are easy to separate oil products. The resulting complex can be converted into alkali nitrogen (basic nitrogen compound) through alkali washing, generally including amines, pyridine, quinoline and their homologues. The current question is: Are there any good processing and utilization technologies for these alkaline nitrides? Forum friends please speak more!
It's almost all colloidal asphaltene and alkaline nitrogen. It's mixed with heavy oil and burned.
I heard that nitrogen residue is recycled into phosphate fertilizer, but I don’t know how.
That is also after the nitrogen residue separates the oil and water phases.
These ones with very little alkaline nitrogen can be sold directly to the outside world.
I hope there is better technology that can turn waste into treasure

The other is that the refinery has high environmental protection and efficiency requirements. It hopes to recycle the oil in the nitrogen residue (recycling can only be mixed with heavy oil for burning). The remaining water phase is used as a raw material for making fertilizers. The first one is simple, the second one is environmentally friendly and has certain benefits.
What additives are generally needed for complex denitrification?
It was mixed with heavy oil and burned. Has the flue gas been sampled and analyzed? Is it serious about air pollution?
