年产500吨5氯2羟基苯乙酮的工艺设计(3)
In brief, the chemical design plays an important role in the new factory (workshop or installment) construction, the old factory transformation and the small scale experimental or the medium scale experimental installment. That is, the design is a necessary route for the scientific research achievement transforms for the industrialization big production must pass through the way.
1.Duty origin
This design is slightly tries according to the 5-Chloro-2-hydroxyacetophenone scientific research to report and the experimental empirical datum. Its goal is carries on a time of chemical design attempt using the chemical engineering correlation knowledge, and is the 5-Chloro-2-hydroxyacetophenone industrialization production; the production installment design provides the reference. As the simulation design, this article has abbreviated the chemical design partial contents, like craft pipeline design, explosion-proof electricity design, powerdesign and factory whole arrangement and so on.
2.Design standard
This design has referred to below the national standard and the stipulation.
a. Production process dangerous material and harmful factor classification and code.(GB/T13816-1992)
b. Commonly used dangerous chemistry classified standard.(GB13690-1992)
c. Inpressure vessel chemistry medium model harm and explosion hazard degree classification (HGJ43-1991)
d. Factory fire protection stipulation (GBJ16-1987)
e. The sewage synthesis discharges the stipulation (GBJ8978)
f. The steel pins down the pressure vessel (GB150)
g. Shell type heat interchanger standard (GB151)
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) Safe: In the chemical production the massive matter are flammable, explosiveor are virulent. Therefore, the design must fully consider each kind is obvious and the latent danger, the guarantee production personnel'shealth and the security.
(2) Ease of operation: While determines each production process and equipment, but also must reasonably determine the operating condition. Because of it to the production process and the equipment establishment and it’s the function display and the control plan determination, all has the direct relations.
(3) Investment province: 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 request. Specially should consider the large-scale equipment the hoisting, in the factory the path pavement structure and the load standard and so on should satisfy the work the request.
