This paper studies the application of mechanic seal to chlorinating container,based on the theory of kinematics and dynamics,analyzes various factors which influence the seal effect and puts forward some metheds for improving the operational per formance.

Heat transfer calculation of esterification reactor jacket;

Saponification reactor proposed is based on laboratory saponification process,in order to meet the requirements of the process reactor design professionals,learn from the mature conventional reactor design theory,according to the particular process of the saponification process has the following aspects of the design of innovation:1.

The batch chemical reaction kettle has the characteristics of big inertia,pure time-delay and nonlinearity,exact mathematic model is hard to be obtained,and conventional PID control can not meet the request of production.
