Also, it can be reference of making control strategy and designing the controller. In this paper, we analyzed the phenomena of multiplicity based on the main part of real chemical process, the system of reactor and flash drum. Also, we discussed the transformation of stead- state point because of recycle. The transformation of stead- state point will influence the conversion and production. The change of production do affect the quality of goods. Therefore, in order to have a steady production, we should use the controller to control the state variable such as temperature, pressure, liquid level, etc. In order to avoid the changes of external disturbances, we used the MIMO global linearization control system to design the controller. This kind of controller can eliminate all the influences of external disturbances and decoupling performances. In addition to, we compared the performances of this controller with one of traditional PI controller. We found that the global linearization control had done an excellent performances from imitative result.
