Abstract
Due to the huge increase of petrochemical projects in Egypt in the last few years, it became very important to secure the transfer and the storage of the petrochemical products and the chemicals used in these products. This can be done by protecting both pipelines and storage tanks from corrosion to prevent the loss in transferred objects through the pipelines (Gas or Liquid) and exposition to the surrounding medium. This may cause very dangerous situations like spills, production interruption, destructions of surrounding environment and ending with great explosions. The same can be said about the storage tanks. Corrosion protection can be achieved by the use of impressed current cathodic protection system. This system is consisted of three main parts the anodes, the cia power source and the anode bed.
In this study we are concerned with the d.c power supply and the anode bed design
Two excellent computer programs were developed for designing the cathodic protection anode bed for both pipelines and tanks bottom by using MA TLAB language. These programs give the optimum solution for all the components of the anode bed.
For the power supply source renewable energy was suggested as a mean for the cic supply to the cathodic protection system. Solar panels and wind turbines were tried aDd then a hybrid ofboth wind power and solar power was tested.
The two programs were tested by using actual case study in a petrochemical ccmpany. Two case studies were involved the actual design of the cathodic protection of a pipeline and a storage tank. The designed technique was compared with the existing CCIIKtitions and comments were developed.
This developed technique for cathodic protection can be used to design any new cathodic protection system by specialist engineers in a very easy way. The method showed to be effective, less expensive, compatible with the environment and more CODvenient to areas where electric power supply is not available.
