The role of nitrogen protection in hydrogenated feed oil
Thread Content
Whether it is straight-run or secondary processed raw materials, they must be protected in the storage tank. The main function of protection is to prevent contact with oxygen in the air. During storage, the sulfonic acid produced by the oxidation of aromatic mercaptans in the raw material can undergo a condensation reaction with pyrrole to form a sediment. ； Alkenes react with oxygen to form oxides, which in turn polymerize with active heteroatom compounds containing sulfur, oxygen, and nitrogen to form sediments. Sediment is the precursor of coking. It is easy to further condense and coke in higher parts of downstream equipment, such as heat exchangers and reactor tops, causing the pressure drop of the reactor and system to increase and the heat exchange effect to decrease.

Nitrogen, as an inert gas, is used everywhere in the coal chemical industry. Whether it is coal-to-liquids or olefins, coal-to-gas methanol. . . . Not only can it be used as a protective gas, nitrogen can also be used as a fire extinguisher, to purge pipes, to replace combustible gas, to seal dry gas, etc. It has many uses.~~~
