Ph Neutralization process modeling

 

                   Continuous stirred tank model

In the figure ：F（t）— Flow of incoming acid , Company ： l / minute , As a constant

      U（t）— Incoming alkali flow , Control quantity , Company ： l / minute ;

      Xa— Concentration of incoming acid , Company ： Equivalent concentration （N）, As a constant ;      

      Xb— Concentration of incoming alkali , Company ： Equivalent concentration （N）, As a constant ;

      C1— Total concentration of sulfuric acid , Company ： Equivalent concentration （N）;

      C2— Total concentration of sulphuric alkali , Company ： Equivalent concentration （N）;

      V— Reactor volume , Company ： l , constant .

Strong acids and bases are completely ionized ：C1=[H+],C2=[OH-], be ：

The total amount of solution flowing out of the container =[F(t)+U(t)]C1;

The total amount of acid flowing in =F(t)Xa;

The amount of change in the total acid in the container =VdC1/dt;

The difference between the total amount of incoming solution and the total amount of outgoing acid is the change of total acid in the container

Again , Alkali also has the following equilibrium equation

The static equation is obtained from the ionization equilibrium

For monobasic strong acids and bases ai by 1, The titration equation is

Make

, have to
