Background
In the process of petroleum processing and refining, concentrated sulfuric acid is generally used as a catalyst to produce high-octane alkylate oil. 80 kg-100 kg waste sulfuric acid is generated every 1 ton alkylate oil production, the sulfuric acid concentration is about 85% -90%, the rest is organic polymer and a small amount of water, the organic polymer is mainly macromolecular olefin, diene, alkyl sulfonic acid, sulfuric ester and sulfide dissolved in the organic polymer, and the monomer type reaches more than 300. The waste alkylated sulfuric acid is a colloidal liquid with high viscosity, is black and red in color and unstable in property, emits special odor, and if the waste alkylated sulfuric acid cannot be properly treated, not only is the waste of resources caused, but also serious harm is brought to the ecological environment.
The method for treating the alkylation waste sulfuric acid mainly comprises the following methods: freezing crystallization method, solvent extraction method, phosphate fertilizer production method, high-temperature pyrolysis method, white carbon black and petroleum rust inhibitor production method, oxidation method and the like.
The freezing crystallization method is to use frozen isobutane to contact with waste sulfuric acid in a countercurrent manner to crystallize and separate the sulfuric acid, but the filtrate obtained by the method has complex components and high content of acid ester, and is difficult to process; the solvent extraction method can reduce the consumption of the alkylated acid by 65-75%, but has large solvent loss and high regeneration cost. The process for producing phosphate fertilizer features that the waste alkylated sulfuric acid is diluted, separated, deodorised and neutralized to obtain phosphate fertilizer, but its organic substance separation effect is poor, fertilizer efficiency is not high and a lot of waste dregs are not treated. The high-temperature cracking method cracks the waste sulfuric acid at the high temperature of 1000-1100 ℃, and then prepares a qualified sulfuric acid product through washing, contact conversion and absorption, but the method has the disadvantages of complex process, high energy consumption, large investment and higher equipment maintenance cost. The method for producing the white carbon black and the petroleum antirust agent has the advantages that although the treatment of the waste sulfuric acid is more thorough, the process route is complex, the product market is very general, and the method is gradually replaced by an alkylation regeneration process technology. The oxidation method is to oxidize the reducing substances of the alkylated waste sulfuric acid by adopting a strong oxidant to realize the regeneration of the alkylated waste sulfuric acid, the method needs a large amount of oxidant and has higher cost, and nitric acid oxidation can also generate nitrogen oxide pollution.
