    1、 What is mixing and mixing? 1: Reduce the heterogeneity (phase, temperature, concentration, etc.) of the system to achieve the required process results 2: The key objectives are quality transfer, heat transfer, reaction and product characteristics 2、 What are the consequences of mixing and mixing poorly? It is very important to successfully produce products that meet the process objectives If the products produced in the process of process amplification fail to reach the required productivity, quality and performance, the production cost will increase significantly More importantly, when the capital and time are invested to improve the mixing and mixing effect, the market may be lost The cost of solving the mixed problems in the production process may be much more than that of fully evaluating and solving the mixed problems in the process development In order to improve the mixing effect, the cost is huge In the chemical industry in the United States, for example, the loss caused by poor mixing and mixing is about 5% In 1989, the chemical industry alone lost $1-10 billion In 1993, a multinational chemical company lost $100 million due to its poor mixing effect 3、 To what extent is the mix sufficient? When will over mixing reduce production rate and product quality? It depends on the sensitivity of product quality and selectivity to mixing intensity and time This requires a detailed understanding of these through experiments or simulations prior to process development and amplification 4、 How to solve the new problems of mixing and mixing? First of all, ask, "why is this problem?" And "how did this problem arise?" This requires communication with operators and chemical workers in charge of process development Then these questions evolved into "how can we zoom in like this?" And "how can the conditions of the laboratory and the factory be so different?" The importance of these issues may always be underestimated However, most engineers only ask geometric similarity and reaction conditions Good experimental design requires a detailed understanding of the mixing mechanism, so as to obtain useful experimental results Engineers who don't know the mixing mechanism may be taking a risk.
