Abstract

The compatibility problems become the main concern in the utilization of biodiesel especially regarding degradation and corrosion. The present study is conducted to describe the corrosion behaviour that occurs in steel tanks after contact with palm-based biodiesel for a period of 7 months. The storage tank used is respectively made of galvanised steel (GS), carbon steel (CS) and stainless steel (SS). It is performed in vertical cylinders with a floating-roof model. In every 30 days of storage time, the profile changes in the wall, roof and base surface of each tank were observed. The oil fuel properties were monitored in the parameter of viscosity, acid numbers, water content and oil colour. The topographic profiles on the surface of the walls and bottom of each tank wetted by biodiesel were examined over three zones inside the tanks using an endoscope imager. The main results of this study indicate that tank steel with different protective layers exhibits different types of corrosion. The corrosion was localized in SS tanks but generalized in GS and CS tanks. The oil contamination in SS tanks was relatively lower than that in CS and GS tanks. The type of corrosion performed differently in different zones on the inside of the tank. The potential for leaks is greater at the base than on the walls and roof of the storage tank.

生物柴油储罐技术评价;腐蚀案例研究

相容性问题成为生物柴油利用中的主要问题，尤其是降解和腐蚀问题。本研究旨在描述钢制储罐在与棕榈基生物柴油接触7年后发生的腐蚀行为 月。所用储罐分别由镀锌钢（GS）、碳钢（CS）和不锈钢（SS）制成。它是在带有浮顶模型的垂直圆柱体中执行的。每30 在储存时间的几天内，观察了每个储罐的壁、顶部和基面的轮廓变化。通过粘度、酸值、含水量和油的颜色等参数对油的燃料特性进行了监测。使用内窥镜成像仪在储罐内的三个区域检查了被生物柴油润湿的每个储罐的壁面和底部的地形剖面。本研究的主要结果表明，具有不同保护层的储罐钢表现出不同类型的腐蚀。SS储罐中存在局部腐蚀，但GS和CS储罐中普遍存在腐蚀。SS储罐的油污染相对低于CS和GS储罐。储罐内部不同区域的腐蚀类型不同。储罐底部的泄漏可能性大于储罐壁和顶部的泄漏可能性。
