Effect of Cigarette Butts Extraction on the Corrosion Rate of ASTM A36 for Jacket Platform

Abstract

Jacket platform is one type of offshore building that used for the offshore oil exploitation process. In general, the Jacket is designed with an operating life of 20 to 25 years and in operation must be guaranteed the safety and strength of the Jacket structure. One of the safety factors that must be considered is corrosion growth in all parts of the Jacket structure. To overcome corrosion problems, there is a need for alternative corrosion improvements, namely the prevention of corrosion by using corrosion inhibitors. The organic inhibitor that can be used as corrosion inhibitors, one of which is cigarette butts, because it is contains a lot of nicotine. Nicotine can be used as an inhibitor by donating nitrogen atoms to nicotine to Fe2 + atoms so that complex compounds [Fe (NH3) 6] 2+ are formed. This compound has a higher stability than Fe so that it can be used as protection in corrosion. The purpose of this research is to solve the cigarette butts problem by creating it a corrosion inhibitor to minimize the cost of material replacement, maintenance costs, and over-design. This study is an experiment by using ASTM 36 steel, material will be blast cleaned in advance with abrasive material Steel Grid. Second steps in this study is the coating process by mixing epoxy paint and extraction of cigarette butts, then immersed in corrosive medium namely sea water of Kenjeran. Corrosion rate testing is carried out by using the weight loss method. The highest corrosion rate occurred at 1% mixing with a corrosion rate of 24.61 mpy and the lowest corrosion rate at 2% mixing with a corrosion rate of 13.78 mpy Based on this research it can be concluded that the nicotine that can be used as cathodic protection on coatings.
