DESIGN OF A CATHODIC PROTECTION SYSTEM TO PREVENT CORROSION OF METALLIC STRUCTURES USING HYBRID RENEWABLE ENERGY SOURCES

Abstract

This paper presents a study to design a cathodic protection system to protect metallic structures against corrosion using hybrid renewable energy sources. The corrosion of pipelines and storage tanks may cause very dangerous situations such as spills, production interruption and destructions of surrounding environment ending with great explosions. An effective method is to use impressed current cathodic protection system to overcome corrosion. This method can be applied to real systems based on hybrid renewable energy sources. A generic program is developed to design the full system with all details to achieve the best performance including the d.c. source. The possibility of supplying the cathodic protection system by wind and/or small solar panel and few nickel cadmium batteries eliminating the external power is also researched. The results revealed the possibility of designing the impressed current cathodic protection system for different configurations. It will be also possible to obtain better performance for the system through increasing the life time of the system. ‫الجحث‬ ‫ُزا‬ ‫يِتن‬ ‫ثتقذين‬ ‫دساسخ‬ ‫هٌظْهخ‬ ‫لتصوين‬ ‫كبثْديخ‬ ‫حوبيخ‬ ‫الوتدةذدح‬ ‫الطبقةخ‬ ‫هصبدس‬ ‫ثإستخذام‬ ‫التأكل‬ ‫هي‬ ‫الوعذًيخ‬ ‫االجضاء‬ ‫لحوبيخ‬ ‫الوختلطخ‬. ّ ‫االصعبج‬ ‫ثبلغخ‬ ‫عوليخ‬ ‫التأكل‬ ‫ظبُشح‬ ‫تعتجش‬ ‫ثبلٌسجخ‬ ‫ل‬ ‫التخةضيي‬ ‫ّهستْدعبد‬ ‫لخطْط‬ ‫نًِة‬ ‫حيةث‬ ‫ب‬ ‫الحةبالد‬ ‫هةي‬ ‫الثييةش‬ ‫تسةجت‬ ّ ‫االًتبج‬ ‫اًقطبع‬ ،‫السْائل‬ ‫اًسثبة‬ ‫رلك‬ ‫في‬ ‫ثوب‬ ‫الحشجخ‬ ‫الوحيطةخ‬ ‫الجيئخ‬ ‫تذهيش‬ ، ،‫لةزا‬ .‫تتديةشاد‬ ‫ثحةذّي‬ ٔ‫تٌتِة‬ ‫نى‬ ‫يوثةي‬ ‫الحبلةخ‬ ٍ‫ُّةز‬ ‫ي‬ ‫دت‬ ‫حوبيخ‬ ‫التخضيي‬ ‫ّهستْدعبد‬ ‫الخطْط‬ ‫تلك‬ ‫طشية‬ ‫عةي‬ ‫الثبثْديةخ‬ ‫الحوبيةخ‬ ‫ًظةبم‬ ‫نُوِةب‬ ‫هةي‬ ٔ‫التة‬ ‫الوختلتخ‬ ‫الحوبيخ‬ ‫ًظن‬ ‫ثإستخذام‬ ‫التيبس‬ ‫ضخ‬ ‫هشثلخ‬ ٓ‫لتتبد‬ ‫التآكل‬. ‫الوتدةذدح‬ ‫الطبقخ‬ ‫هصبدس‬ ‫ثإستخذام‬ ‫حقيقيخ‬ ‫هٌظْهخ‬ ٔ‫عل‬ ‫الطشيقخ‬ ٍ‫ُز‬ ‫تطجي‬ ‫ّتن‬ ‫الوختلطةخ‬. ‫تةن‬ ‫ّقةذ‬ ٔ‫آل‬ ‫حبست‬ ‫ثشًبهج‬ ‫تصوين‬ ‫لتحقية‬ ‫تتبلةيلِب‬ ‫ثثةل‬ ‫كبهلةخ‬ ‫الحوبيخ‬ ‫هٌظْهخ‬ ‫لتصوين‬ ‫هصةذس‬ ‫رلةك‬ ٔ‫فة‬ ‫ثوةب‬ ‫االهيةل‬ ‫االداء‬ ‫التغزيةخ‬ ‫ث‬ ‫بلتيةبس‬ .‫الوستوش‬ ّ ‫تةن‬ ‫فة‬ ‫الجحةث‬ ‫ال‬ ‫هٌظْهةخ‬ ‫تغزيةخ‬ ‫إهثبًيةخ‬ ٔ ‫حوبيةخ‬ ‫ال‬ ‫ثبثْديةخ‬ ‫الشيةب‬ ‫طبقةخ‬ ‫طشية‬ ‫عةي‬ /ّ ‫الشوسةيخ‬ ‫الطبقةخ‬ ّ‫ن‬ ّ ‫هةي‬ ‫قليةل‬ ‫عةذد‬)‫(ًيثل/كبديويْم‬ ‫الجطبسيبد‬ ‫هصة‬ ٔ‫إلة‬ ‫اللدةْء‬ ‫ثةذّى‬ ‫ّرلك‬ ‫التقليذيةخ‬ ‫الطبقةخ‬ ‫بدس‬ ‫هيةل‬ ‫الثِشثيةخ‬ ‫الشةجثخ‬. ‫الٌتةبئج‬ ‫طشية‬ ‫عةي‬ ‫التأكةذ‬ ‫ّتةن‬ ً‫ثأ‬ ‫ّالتحليالد‬ ‫الووثي‬ ‫هي‬ َ ‫تصوين‬ ‫ك‬ ‫حوبيخ‬ ‫ًظبم‬ ‫فعبل‬ ‫بثْديخ‬ ‫التشثخ‬ ‫نًْاع‬ ‫هي‬ ‫ًْع‬ ‫هي‬ ‫ّألكيش‬ ‫هحتولخ‬ ‫هٌبخيخ‬ ‫ظشّف‬ ‫عذح‬ ٔ‫ف‬ َ‫ّإًة‬ ‫لل‬ ٌٔ‫الضه‬ ‫العوش‬ ‫ثضيبدح‬ ‫ّرلك‬ ‫للوٌظْهخ‬ ‫نداء‬ ‫نفضل‬ ٔ‫عل‬ ‫الحصْل‬ ً ‫نيضب‬ ‫الووثي‬ ‫هي‬ ّ ‫خطْط‬ ‫ال‬ ‫وستْدعبد‬ .
