2.Scientific experiments Any one science experiment, from small-scale model test, intermediate test, until the transition to industrial production, are inseparable from the design. From the development process of the modern petrochemical industry, scientific research increasingly plays an important role. Make scientific research to achieve industrialization, must be closely integrated research and design development of new processes, new technologies, new products and new equipment, etc. Therefore, it is the bridge of scientific research achievements of industrialization. 3.Basic chemical building Chemical Engineering Design is the first link of the chemical industry infrastructure is also an important basis for on-site construction. To the full set of devices from a single device from a small chemical plant to large-scale chemical enterprise, they must first do a good job in engineering design prior to construction, but also in the whole construction process, from beginning to end based on the engineering drawings as the basis. To build an excellent quality, the level of state-of-the-art chemical plants, important prerequisite is to ensure that there is a high-quality, high-level design. Improve the quality and speed of the engineering design plays an important role in the development of infrastructure. All in all, the design work is not only useful to design a new plant, but the old plant has been put into production, how to properly operate the equipment, to discover and address the weak links in the production and unreasonable to propose process improvements to simplify the production process, reduceconsumption of energy saving, development of new resources and improve production efficiency, waste management and other measures are very necessary for the industrialization of scientific research and design work in close coordination. Therefore, raising the level of chemical design and development, China's economic construction, national defense construction, told the development of great impact, be sure to give very great importance. 1.Duty origin This design is slightly tries according to the o-phenetidine scientific research to report and the experimental empirical datum, and has referred to a commercial scale simulation design which the Jiaojiang chemical industry four factories p-phenetidine production installments does. Its goal is carries on a time of chemical design attempt using the chemical engineering correlation knowledge, and is the o-phenetidine 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. (责任编辑：qin) |
