ATC (Automatic Tank Cleaning) is an advanced automatic, fully enclosed and physical cleaning technology. It cleans the tank by jet washers to spray the cleaning medium at a certain temperature, pressure and flow rate, to remove the coagulum and sludge on the surface, and to recover the effective substances to achieve the conditions of in-tank overhaul and hot work.
Introduction of equipment
"ATC (Automatic Tank Cleaning) is an advanced automatic, fully enclosed and physical cleaning technology. It cleans the tank by jet washers to spray the cleaning medium at a certain temperature, pressure and flow rate, to remove the coagulum and sludge on the surface, and to recover the effective substances to achieve the conditions of in-tank overhaul and hot work. It has the advantages of high safety, good economic benefits (more than 98% of hydrocarbons in sediments can be recovered), good cleaning effect, high efficiency, environmental protection, etc.
Landa's ATC is suitable for cleaning various types of above-ground storage tanks with storage media of crude oil, refined oil (gasoline, diesel oil, aviation kerosene, lubricating oil, etc.) and chemical liquefied products, with storage tank volume ranging from 100 cubic meters to 150,000 cubic meters."
Unit Configuration
| No. | Unit Name | Description | Main Part |
|---|---|---|---|
| 1 | Circulation and Transfer Unit | Core unit of ATC. It is used to realize the whole cleaning process, provide pumping pressure, raise the temperature of cleaning liquid and recover the liquid in the tank. | 2 sets of centrifugal pumps, water-ring vacuum pump, cooling water pump, vaccum tank, heat exchanger, EX-proof distribution box, and PLC control box. |
| 2 | Steam and Protective Gas Generating Unit | Provide inert gas protection for cleaning activities and steam heat source | Disel boiler, soft water system, soft water tank, diesel tank, cooling water tank |
| 3 | Nitrogen Making Unit | Provide nitrogen for cleaning activities | Air compressor, air storage tank, adsorption treatment system |
| 4 | Oil-gas Seperator Unit | Used for separation of oil and water during warm water cleaning, recycling warm water and transferring recovered oil to designated oil tanks. | One set of 2'' pneumatic diaphragm pump, level gauge, thermometer |
| 5 | Air Supply and Distribution Unit | Provide power distribution and gas supply for whole system. | General distribution box, screw air compressor, air storage tank, drying tank, air distribution bag |
| 6 | Jet washer | Compressed air is used as power drive, which is safe and reliable. The cleaning angle is 360° horizontally and 140 °vertically. There is no dead angle in all directions. |
