1. determination of production methods

The concrete steps for preparing pyridine butane sulfonic acid sulfate are as follows: preparation of ingredients， preparation of intermediates， cooling， filtration， drying，water dissolution，aeration，pressure，degassing，cooling and cooling.

2. determine the scale of production

 In the daily chemical production practice，the optreation is different with the laboratory， we must consider the production process of the consumption cost， how to ensure that the environment is not polluted，placing equipment locations and other issues， so the need to reduce pollution in the production process design， improve the quality of production equipment，reduce production costs，reduce the not necessary engineering people control equipment，enhance the recovery of various material recycling， finally decided to pyridine and butyl sultone as raw material for the production of pyridine butane sulfonic acid sulfate，reaction in the reaction vessel specified， put some raw materials，daily production of about 8 hours，can get on the yield of pyridine butane sulfonic acid sulfate 1kg， to 300 days a year， the annual output of 300 kg.

3. material balance and energy balance

Material balance calculation and energy balance calculation are the basis of chemical process design and techno economic evaluation. In the process of the whole production process and device through the material balance and energy balance balance balance， resulting in the yield of main products，raw materials consumption quota， material loss results，in this process， according to the calculation results of material and energy balance，we can carry on design and production equipment. Determine the technical and economic indicators such as product costs，quantitative evaluation of the selected process routes，roduction methods and processes，economic and reasonable level， advanced level of technology.

4. equipment selection and equipment calculation

The graduation project is mainly from the reactor selection，equipment，materials， reaction conditions，control，and equipment structure，a certain process equipment selection. Through the calculation of some equipment，the whole process of design and construction，the type of process equipment needed，and finally the whole design.

5. construction drawing design

Construction drawings for the production of 300 kg per year of butane sulfonic acid sulfate are required:

Process flow chart，plant equipments layout and so on
