PRODUCTION DESIGN WITH AN ANNUAL

OUTPUT OF 100 Thousands TONS OF 

ETHYL ACETATE

Instruction manual:

Project: the annual production capacity of 100,000 tons of ethyl acetate production process design 

Ethyl acetate alias ethyl acetate, is an important fine chemical materials。 It is a good solubility and quick drying of the solvent, widely used in production life。 For example: widely used in chemical, pharmaceutical, textile, dyes, coatings, inks and other production。 At present, the industrialization of ethyl acetate production process has matured, while acetaldehyde condensation because of its: a wide range of raw materials, environmental protection and other advantages in a variety of production stand out, is one of the most promising prospects for the production process。With the rapid development of the national economy and the world economy, the chemical industry has also been rapid development。 Chemical products everywhere, always filled with our lives, our lives can not be separated from the development of the chemical industry。 Then the construction of a chemical plant, first of all we have to do is to carry out chemical design, a good chemical design program is a necessary prerequisite for building a factory, a good design not only in the process to be prominent, but also in energy saving Has been optimized, so that the company can save a lot of production costs。 This reflects the importance of chemical design。 In the chemical production, in order to adapt to the development of the industry, the national economic development, we will have to transform the existing chemical plant and expansion, which requires us to use professional knowledge of chemical design and design, to achieve our The required output。 At the same time, with the development of technology, chemical technology process is also constantly improving the chemical process technology is also more advanced to the direction of development, then the original production process will need to continue to improve and improve the same time in the production process , There will be unreasonable or weak links, which requires us to use chemical knowledge of the production process to continue to determine and optimize to achieve the most advanced level。 At the same time in scientific research, from an experiment to the construction of a factory, this process is a process of industrialization of the product, the process needs to go through a small test, pilot, large-scale production and other three processes, each experimental stage we need to Industrial design, so that the whole process can be completed。 At the same 

time, chemical design also plays a significant role in unit production equipment or the entire plant for production capacity calibration and technical and economic indicators。
