Crude oil tank cleaning Equipment
1、Crude oil tank cleaning equipment working principal introduction
1.1 Working Principal
At first, using the temporary pipes connect the 150,000m3 crude oil tank or smaller and the equipments to be a closed loop cleaning system . after that, use the same oil as the tank storage to broke the oil sludge. when the sludge is broken, to become liquid and small, it will be pumped out, and be separated、recycled, when most sludge and oil is pumped out, than, using hot water to clean the tank, at last, the tank will be cleaned up. This closed process is called crude oil tank cleaning technology.
1.2 technological process
Bottom oil transfer→ inject Nitrogen→ oil cleaning→hot water cleaning→open manhole/ventilate→clear up
2、Product oil storage tank cleaning system working principal introduction
2.1 working principal
At first, using the temporary pipes connect the 50,000m3 refined oil tank or smaller and the equipments to be a closed loop cleaning system . after that, using hot water to clean the tank, the oil /water will be pumped out, and be separated、recycled , at last, the tank will be cleaned up. This closed process is called refined oil tank cleaning technology.
2.2 technological Process
Equipment installation→inject Nitrogen→hot water cleaning→open manhole/ventilate→clear up
3、Equipment introduction
