1. Duty origin

This design is an industrial scale simulation designed based on the scientific pilot test report of 1H-1,2,4-triazole-3-carboxylic acid methyl ester and related experimental data. Its fundamental purpose is to use a chemical engineering-related knowledge and operating methods to conduct an analog chemical design attempt, and to provide reference for the design of industrial production of 1H-1,2,4-triazole-3-carboxylic acid methyl ester.As the simulation design, this article has abbreviated the chemical design partial contents, like craft pipeline design, explosion-proof electricity design, and power design and factory whole arrangement and so on.

2. Design standard

This design has referred to below the national standard and the stipulation.

a. Commonly used dangerous chemistry classified standard.（GB13690-1992）

b. Production process dangerous material and harmful factor classification and code. （GB/T13816-1992）

c. In pressure vessel chemistry medium model harm and explosion hazard degree classification. （HGJ43-1991）

d. The steel pins down the pressure vessel. （GB150）

e. Shell type heat interchanger standard. （GB151）

f. Factory fire protection stipulation. （GBJ16-1987）

g. The sewage synthesis discharges the stipulation. （GBJ8978）

h. Craft system arrangement of equipment design stipulation. （HG20570）

i. Chemical installment piping arrangement design stipulation. （HG/T20549）

3. Principle of design and main design standard

Principle:

（1） Safety: In chemical production, a large number of flammable, explosive or toxic compounds are produced. Therefore, the design must fully consider various obvious and potential dangers to ensure the health and safety of production personnel.（2） Ease of operation: In determining the various production processes and equipment, but also to determine the reasonable operating conditions. Because it has a direct relationship with the establishment of production processes and equipment, as well as the determination of its role and the determination of control programs.

（3）Saving investment: Namely the request economically uses the equipment investment, the construction invests, the public project investment and the manpower cost.

（4） Is advantageous for the installment: The factory arrangement should satisfy the construction and the installment work requirements. In particular, the lifting of large-scale equipment should be considered. The pavement structure and load standards of the roads in the factory should meet the requirements for construction and installation.

Key words：Methyl 1,2,4-triazole-3-carboxylate; 1,2,4-Triazole; process design; reactor
