The cost of mechanical cleaning for vertical storage tank, API standard 650 aboveground steel oil storage tanks is low, almost all oil can be recovered, and the quality of recovered oil is high. The cost of manual cleaning for vertical storage tank, API standard 650 aboveground steel oil storage tanks is high, the oil can not be recovered completely, and the quality of recovered oil is low. The mechanical cleaning of API standard 650 aboveground steel oil storage tanks adopts fully enclosed operation, and separates oil, water and oil sand. There is no direct discharge of oily sewage and waste gas, which will not pollute the environment.
