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) operation is simple: adhere to the scientific attitude to determine various production process and equipment and the operation condition reasonably, striving to achieve the mild reaction condition and low requirements of equipments and convenient operation of the workers as the result.
(3) reasonable economy: reduce equipment costs, raw material costs, labor costs and other aspects investment effectively and reasonably.
(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 40000 tons
Days to 300 days in，45 days for machine maintenance, 15 days mobile
Keywords: benzaldehyde; benzoic acid ; process calculation
