The invention relates to antichlor, which belongs to the technical field of fine chemical engineering. The antichlor comprises 20 to 40 percent by weight of aliphatic amine, 30 to 50 percent by weight of alicyclic amine and 10 to 30 percent by weight of alkylol amine. The antichlor is prepared by filtering the raw materials after being uniformly blended to remove impurities. The antichlor is a water soluble flux, has good compatibility with electro-desalting medium, has a synergistic action on the salt content after the electro-desalting of an atmospheric and vacuum distillation unit, has remarkable effect on removing the cchloride ion concentration of drainage and naphtha on top of the device, can effectively improve the corrosion resistance of the device and prolong an on-stream time, is simple to operate and low in cost, and has remarkable economic benefit of the device.
Description
technical field [0001] The invention relates to a dechlorination agent, which belongs to the technical field of fine chemicals. Background technique [0002] Atmospheric and vacuum units play a dominant role in oil refining units. After heat exchange, the raw oil enters the electric desalination process for water washing, demulsification and desalination, and regular and vacuum distillation to obtain light naphtha, gasoline, diesel oil and heavy oil. Crude oil is composed of more than 95% carbon and hydrogen compounds, and the remaining 5% is organic and inorganic heteroelement compounds composed of sulfur, chlorine, nitrogen and metal elements. Although the content of such compounds is small, it affects the quality of the entire refinery. Process and product quality. From the perspective of corrosion and anti-corrosion, some of these impurities contained in crude oil are themselves corrosive media, such as hydrogen sulfide, elemental sulfur, mercaptans, organic acids, etc....
