Abstract

In order to study the factors affecting on the washing effect of chemical tankers, palm oil was selected as a typical non-volatile chemical cargo, stainless steel lined bulkhead chemical tanker was taken as a research object, while a physical experiment system was built and developed a reliable numerical simulation model was developed. The quantitative evaluation model of palm oil tank washing effect was obtained by analyzing the results.During the experiment, it was found that the water jet was mainly influencing factor in the initial stage, and the dissolution of tank washing water in the middle and later stage was the mainly influencing factor. The research results show that, the main factors affecting the tank washing effect are the length and diameter of the nozzle outlet, washing time, temperature of the tank washing water and dynamic pressure.  This work has theoretical reference value for related research and good guidance significance for the practice of chemical tanker washing.
