General description of the mobile system
The JetPetroClean™ Spectrum system is designed for scheduled maintenance of the tanks at the petrol filling stations, factory territory. The system allows internal cleaning and degassing of fuel storage tanks in order to prepare them for internal inspection (flaw detection) and for possible repair works inside the tank, including fireworks. The main advantage of the system is its complete autonomy and the ability to perform internal cleaning of the tanks in automatic mode. The system does not require connection to electricity, water supply and other resources on the site, which allows it to be used in almost any condition or condition of the filling station. The system has its own diesel generator and air compressor to ensure the operation of the entire equipment of the system. The system is assembled in a standard frame of a universal 20f container and can be transported to the work site by any truck which has a load capacity of up to 14 tons. The system can be operated directly stationed on the vehicle or can be removed from the vehicle and installed on the work platform separately. The system is designed to work with light oil products: gasoline, diesel fuel. It is also possible to use the system to clean petrochemical products with a density less than the density of water. The working pressure of the inner tank cleaning is 6 … 10 bar. In addition to servicing, the system can also be used for internal cleaning of distributor tanks (tank trucks, ISO tank containers, railway tank wagons), stationary horizontal tanks at tank farms and vertical tanks with a volume of no more than 2000 m3 and process pipelines.
System includes:
- Process vessel for flush water
- Two multistage electric pumps
- Ejector pump
- Diaphragm Pneumatic Pump
- Degassing fan
- Two hose reels
- Pipe manifold with actuated valves
- Diesel-electric generator
- Air compressor
The capacity of the electric generator fuel tank is 85 liters. The fuel consumption at 100% load is 9.5 liters per hour, the time of continuous autonomous operation with full fuel filling and the maximum load on the generator is 9 hours. The total electric power of all consumers is 32 kW, the power required to perform the cleaning of the tank is 28 kW. The flush water volume inside process vessel is 3…5 m3. The equipment can be connected to an external power source with an available power of at least 28 kW, in case the generator does not switch on. The system has two operation modes: automatic and manual. In automatic mode, the operator needs to deploy the washing system (install a washing monitor in the tank, connect the monitor and the system by hoses) and start the automatic washing program using the automatic control panel. The system controlled by the program performs the internal washing of the tank. All process parameters are controlled by sensors and master control panel. After the program is complete, it is necessary to turn off the flushing system or move it to the next tank and install a degassing duct into the tank. In manual mode, the operator independently turns on and off the pumps, opens valves (all electrically actuated) and controls the process from the manual control panel. The sensors control the process and it’s the parameters and after the operation cycle stops the washing. The system allows performing work with a minimum number of employees. In the automatic mode, one person can perform the operation for the internal cleaning of the tank, the rest of the cleaning crew can perform other operations (dismounting/assembling tank hatches, working on pipe fittings, etc.). The average time of work at one filling station is 1 working day. Optionally, the system can be additionally equipped with a module for cleaning fuel residues from water and mechanical impurities. The system is designed in accordance with: 2006/42/EC, 2006/95/EC, 94/9/EC; EN 13480 Metallic industrial piping. EN/IEC 60079 Explosive atmospheres. Equipment. EN/IEC 60364 Low-voltage electrical installations. EN 61439-1 Low-voltage switchgear and controlgear assemblies. General rules.

*tools and accessories kit
External pumps intended for pumping from the tank mix of flush water and residue during the tank washing process. Pneumatic diaphragm pumps are used. Electrically driven diaphragm pumps also can be used.
External pumps connects to the Tank cleaning unit and Flush water separator by the hoses and pipes kits. In addition to laying simple lines from the flushing complex to the tank, the elements of a set of pipelines can also be used to install a pipeline for the distribution of flushing water and pumping to the preparation (cleaning) positions of transport tanks.
For degassing use special axial flow fans. The tools and accessories kit includes a hand tool for mounting and dismantling the flushing system directly on the tank, for servicing and minor equipment repairs, and devices for injection steam into the tank when the product residue is heated (steam nozzles, coil heaters, etc.).
