     In this study, a theoretical analysis of optimum bed thickness for realizing a high efficiency and reaction conversion of an electrochemical reactor has been made based on flow-through porous electrode (FTPE) configuration. Another configuration of porous electrode (flow-by) has been reviewed beside the considered one. The method that has been used is to find out a mathematical model to represent the optimum bed thickness by taking a look into previous works concerned and collecting all related information, data, and models.

 The absorption column is one of the essential separation processes in industrial operation, so the need arises to control absorption column by process simulation and also to analyze system by method called frequency response using MATLAB₈ .This work dealt with gas-liquid (air-water) absorption packed column which is analyzed by bode plot and frequency response to determine the stability of the system with or without Proportional Controller (P), Proportional Integral Controller (PI) or Proportional Integral Derivatives Controller (PID).The frequency r

Because of the importance of galvanic corrosion the need arises to study the effect of corrosion inhibitors, area ratio of cathode to anode (Ac/A), on galvanic corrosion of several industrially important metals and also to follow the a behavior of corrosion rate of each member of the couple.  In the present experiments at the first stage, the corrosion potential with time was measured for four types of metals in solution of four pH values. The purpose of this stage is to find out the cathode metal from the anode.
