Introduction of a system for optimizing the equipment for acetal

One, decomposition method

This is a kind of processing method for complex systems in system engineering. The purpose is to decompose the large system that needs integrated into a number of easily processed subsystems, then integrate each subsystem, get local optimal solution, and then use the whole objective function to test it. If you do not meet the overall requirements, you need to coordinate among the subsystems until you get the desired system.

Two, exploration method

According to the rules summed up by the experience, the method of solving the problem is explored. As an example, the good reflux ratio is 1.1 to 2 times as large as the small reflux ratio, but it can only be used as a test rule and is still applicable to most cases, but it can not guarantee the optimal solution.

Three.

Generally, starting from a selected initial system, we adopt a tuning strategy to get a comprehensive method of a better system through a series of stepwise corrections.

Four, direct optimization method

A mathematical method is used to obtain the optimal solution of the chemical process. However, if the process is complex, it is difficult to find a suitable optimization method to deal with it, and therefore the optimal solution can not be guaranteed.

From the understanding of the above methods, the good method at present should be the multilevel synthesis method. It is first to use the decomposition method or the test method to get a better initial process, and then the optimization method is used to modify it gradually so as to realize the understanding and application of the methacetal equipment and technology.
