Method for rapidly removing mercaptan from gasoline

Abstract

The invention discloses a method for rapidly realizing gasoline sweetening. The gasoline with stable components enters the deodorization unit under the conditions of 30-40°C and 0.35 MPa, and fully mixes and reacts with dilute lye with a concentration of 10% through a static mixer. , and then enter the gasoline alkali washing ionizer for pre-alkali washing and refining. Under the action of the electric field, the alkali slag carried in the gasoline is separated to generate a corrosion-qualified electrified gasoline, and the electrified gasoline is statically mixed with the purified air and the activator After fully mixed in the reactor, it continuously enters the gasoline deodorization reactor, and passes through the activated carbon bed layer loaded with sulfonated cobalt phthalocyanine catalyst to oxidize the mercaptan in gasoline to disulfide, so as to achieve the purpose of deodorization. The reaction coming out of the top of the oxidizer Qualified gasoline is refined gasoline, and then enters the three-phase separator, the oxidation tail gas is separated from the top of the tank to the acid gas flare, and the bottom is discharged, and the refined gasoline is sent to the finished product tank area from the upper part through the metering valve group. This process can clean up the sulfur components in gasoline and obtain gasoline with higher purity.

Description

Technical field [0001] The invention belongs to the field of petroleum, and in particular relates to a method for quickly realizing gasoline sweetening. Background technique [0002] Oil and gas are gases that come out of oil wells along with oil, and the main components are methane and ethane. Used as fuel and chemical raw materials. Oil and gas generation has the following conditions. First of all, it depends on the amount of organic matter in the oil-generating layer, which is usually called "organic matter abundance". It mainly measures the residual organic carbon content to determine whether there are oil-generating layers and how many oil-generating layers there are in an area, and divide them into good, medium and poor oil-generating layers according to certain standards for classification evaluation. Second, it depends on the quality of organic matter in the oil-generating layer, which is usually called "organic matter type". According to the biological source, the ker...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the problem that in the existing gasoline treatment, because the interior contains more sulfur components, the treatment efficiency is poor, so that sulfide is produced when the gasoline is finally used, which pollutes the environment and does not meet the standard, and also causes damage to people's bodies. , designed a method to quickly realize sweetening of gasoline. This process can clean up the sulfur components in gasoline and obtain gasoline with high purity. It will not cause environmental pollution during subsequent combustion and use, and also protect people's physical safety. It solves the problem that in the existing gasoline treatment, because the interior contains more sulfur components, the treatment efficiency is poor, which makes the gasoline produce sulfide when it is finally used, pollutes the environment and does not meet the standard, and causes damage to people's bodies.

[0005] To sum up, the beneficial effects of the present invention are: the process can clean the sulfur components in the gasoline to obtain gasoline with higher purity, which will not cause environmental pollution during subsequent combustion and use, and also protect people's physical safety, solve the problem of In the existing gasoline treatment, because the interior contains more sulfur components, the treatment efficiency is poor, which makes the gasoline produce sulfide when it is finally used, pollutes the environment and does not meet the standard, and also causes damage to people's bodies
