Explain:

  1, reduce the heterogeneity of the system (phase, temperature, concentration, etc.) in order to achieve the desired process results.

  2, the quality transfer, heat transfer, reaction and product characteristics as the key objectives.

What are the consequences of poor mixing and mixing?

  Successful production of products that meet process objectives is critical. If the production in the process in the process of amplification products failed to achieve the yield, quality and performance are needed, so the cost of production will increase significantly, more importantly, in the investment of time and money to improve the mixing effect, may lose helplessly looking at the market.

  The money spent on solving mixed problems during production may be far more than the cost of evaluating and solving mixed problems adequately during process development. The cost of mixing the effects was enormous. In the United States, for example, in the chemical industry, the losses caused by mixing and mixing were about 5%. In 1989 alone, the chemical industry lost $10-100. In 1993, a multinational chemical company lost $100 million as a result of poor mixing.

  To what extent is it enough? When will low yield and product quality be due to over mixing?

  It depends on the sensitivity of the product quality and selectivity to the mixing strength and mixing time. This requires detailed knowledge of experiments and simulations prior to process development and scale-up.

How are the new problems of mixing and mixing solved? :

  First, ask, "why does that happen?"" And "how did this problem arise?"". This requires communication with operators and chemists who are responsible for process development. Then the questions turned out, "how can we zoom in like this?"" And how can the conditions of the lab and the factory be so different?"

  The importance of these problems may always be underestimated. The vast numbers of engineers just ask questions of geometric similarity and reaction conditions. Good experimental design requires a detailed understanding of the mixing mechanism so that useful experimental results can be obtained. Engineers who do not know the mechanics of mixing may be just taking risks.

Range of mixing operation:

  Mixing and mixing play an important role in many industries,

  Fine chemicals, agricultural chemicals, pharmaceutical industry, petroleum chemical industry, biological technology, polymerization process, paint and auto polishing, makeup and consumer goods, food, drinking water and water treatment, papermaking, mining engineering.
