Deacidification method of acid sludge oil

Abstract

The invention relates to a deacidification method of acid sludge oil, which comprises the following steps: adding the acid sludge oil into a reaction tank, and then, adding 0.5% of fatty acid, 0.15% of aluminum potassium sulfate, 0.1% of hydrogen peroxide, 0.1% of ethylene diamine and 1.5% of sodium hydride according to the weight percent of the acid sludge oil; heating the mixture to 90 DEG C for reacting for at least 5 hours; and separating sulfuric acid of which the concentration is 70% and asphalt for recycling. In the invention, the acid sludge oil which is industrial waste is utilized and is converted into useful sulfuric acid through deacidification treatment, thereby having the advantages of no pollution on environment, simple equipment, low cost, very great economic benefit and social benefit and wide popularization and application.

Description

technical field [0001] The invention relates to a method for deacidification of petrochemical products, in particular to a method for deacidification of acid residue oil. Background technique [0002] The acid residue oil derived from petrochemical refined diesel oil, lubricating oil and coking plants is huge, which poses a serious threat to the natural environment. my country attaches great importance to the comprehensive treatment of acid residue oil. At present, the domestic method of treating acid residue oil is to use high temperature and high pressure to crack acid residue oil and add catalyst and hydrogen during the refining process. This method is relatively complicated and the processing cost is high. Generally, small petrochemical companies do not have such high-end equipment. However, asphalt obtained through acid residue oil treatment is favored by domestic small factories. Cheap acid residue oil and high-profit asphalt prompt the use of outdated production proce...

At present, the domestic method of treating acid residue oil is to use high temperature and high pressure to crack acid residue oil and add catalyst and hydrogen during the refining process. This method is relatively complicated and the processing cost is high. Generally, small petrochemical companies do not have such high-end equipment.

However, asphalt obtained through acid residue oil treatment is favored by domestic small factories. Cheap acid residue oil and high-profit asphalt prompt the use of outdated production processes to treat acid residue. The acidic waste water in the production process is harmful to the soil. It causes great pollution to rivers and oceans, and the exhausted gas contains a large amount of sulfur dioxide and other harmful gases, which poses a serious threat to the natural environment of the air. If this uncontrolled discharge will destroy the civilization of the earth, it is important to treat the earth well and protect the environment. The obligation of each of our citizens, the top priority of comprehensive governance
