年产800吨苹果酯生产车间的设计(2)
1 The source task
This design is for fructone, its purpose is to use chemical engineering knowledge for a chemical design, improving the resolution of chemical products production workshop design actual problem ability; Master of chemical process design, material balance workshop process, equipment selection, layout design and so on the basic methods and steps; from the technical feasibility and rationality of the two aspects of establishing the correct design idea. Through the curriculum design, but also improve the use of computer graphics design ability.
2 Design Standards
The design references the following national standards and regulations.
(1) Production of dangerous goods and harmful factors in classification and code.（GB/T13816-1992）
(2) Dangerous chemical commonly used in the classification criteria. （GB13690-1992）
(3) Typical chemical medium pressure vessel explosion hazards and safety levels. （HGJ43-1991）
(4) Factory fire safety requirements.（GBJ16-1987）
(5) Integrated wastewater discharge requirements.（GBJ8978）
(6) Steel pressure vessel.（GB150）
(7) The standard shell and tube heat exchanger.（GB151）
(8) System and Equipment layout design requirements.（HG20570）
(9) Chemical plant piping design requirements.（HG/T20549）
3 Design principles and key design indicators
Principle：
(1) Safe and reliable: the design of many chemical substances are flammable, explosive or toxic. Therefore, the design must be taken into account of all sorts of obvious and potentially dangerous and used strict regulations of national and local health and safety to ensure little environmental pollution and the health of production personnel.
(2) Easy to operate: In determining the production process and equipment all at the same time, should rationally determine the operating conditions. Because of its production process and equipment to establish its role in the play and control scheme, and has a direct relationship.
(3) Investment Province: Which called for economic use of equipment investment, civil engineering, public works, investment and labor costs?
(4) easy to install: Plant layout should meet the requirements of the construction and installation, with emphasis to consider the installation of large equipment, factory and load road pavement construction and installation standards should meet the requirements.
(5) Basis of calculation:
Annual production of 800tons, the product purity of 99%
Days to 300 days in，60 days for machine maintenance, 5 days mobile
Keywords: fructone; acetoacetate; ethyl acetate; synthesis; process calculation; workshop
