Comparison of the quality of mechanical cleaning and manual cleaning of vertical storage tanks, API 650 unanchored tanks. The mechanical cleaning of the API 650 unanchored tanks can make the inside of the tank be thoroughly cleaned in multiple directions, and the cleaning quality is high, and the cleaned oil does not contain lumpy impurities. While the walls and roof of the API 650 unanchored tanks cannot be cleaned in multiple directions during manual cleaning, and the cleaning quality is not easy to be guaranteed. The oily sewage collected after cleaning usually contains a lot of lumpy impurities, and these oil products are difficult to clean.
