N, N'-di-sec-butyl-p-phenylenediamine simulation teaching factory

Abstract

The invention develops an N, N'-di-sec-butyl-p-phenylenediamine simulation teaching factory, which mainly includes: a chemical apparatus production area, a chemical apparatus control area and a teaching complex area. Specifically, N, N'-di-sec-butyl-p-phenylenediamine production equipment is established in the apparatus production area; the chemical apparatus control area is equipped with a host computer, a DCS control system, a field instrument and a communication network, and the DCS control system is in connection with the N, N'-di-sec-butyl-p-phenylenediamine production equipment through acommunication network; and the teaching complex area includes students' computers, multimedia teaching facilities and simulation operation software. The N, N'-di-sec-butyl-p-phenylenediamine simulation teaching factory provided by the invention can display the whole process of p-phenylenediamine reductive alkylation production equipment, and realize the cooperative operation of equipment start and stop, accident handling and the like. Application of the facilities adopted by the invention to teaching can enable students to operate real and high-risk chemical engineering apparatuses and improve the understanding of safe production and standardized operation.

Description

technical field [0001] The invention relates to a teaching factory in the field of chemical production, which belongs to the technical fields of education, chemical technology and equipment, and is used for pre-job training and professional practice of chemical engineering and related majors in enterprises and colleges. Specifically, it relates to a simulation teaching factory of N,N'-di-sec-butyl-p-phenylenediamine. Background technique [0002] N,N'-di-sec-butyl-p-phenylenediamine (also known as antioxidant 4720), English abbreviation DBPD. Red to brown liquid, completely miscible with hydrocarbon oil, soluble in dilute inorganic acid, insoluble in dilute alkali and water. Antioxidant 4720 is an important chemical additive, mainly used in cracked distillates and gasoline with high olefin content. The induction period of gasoline is shortened, and the carbon deposition in the combustion process of gasoline is reduced. [0003] The industrial production method is the redu...

Problems solved by technology

[0004] The high risk of high-pressure hydrogenation reduction reaction limits the training and practice of this type of production equipment. The existing hydrogenation equipment in the chemical industry practice teaching does not have real chemical production equipment. They are all scaled indoor equipment. The operation is The internal and external operation cooperation of a single post lacks the operation cooperation of the whole process, and cannot give students a sense of reality of chemical equipment
