Application and Risk Control Analysis of Mechanical Cleaning Tank
Large crude oil storage tank is an important equipment for petroleum refining enterprises to store crude oil,the viscous liquid or semi-solid material with high density and poor fluidity settles for a long time and gathers at the bottom of the storage tank,occupying a large storage space,greatly reducing the efficiency of crude oil dehydration,and often clog the filter when feeding due to excessive impurities,which has seriously affected the quality of crude oil and processing efficiency.At the same time,the operation cycle of the storage tank is too long,and the parts in contact with oil and gas in the tank and the outside of the tank are washed by carbon dioxide,sulfur dioxide and rain in the air,and some metal structures of the storage tank are seriously corroded,and there are safety risks,and it is easy to cause fire,explosion,personnel poisoning and other safety accidents during the operation of the oil tank.Therefore,it is necessary to formulate the tank cleaning plan in advance,analyze the safety hazards existing in each operation link in place,and implement safety measures.Due to the large capacity of the storage tank,the complex composition of crude oil,and the tight maintenance time,the traditional manual cleaning tank is not only a big safety risk,but also can not complete the cleaning task within the specified time,CNOOC Ningbo Daxie Petrochemical Co.,Ltd.chooses mechanical cleaning tank instead of manual cleaning tank.
