Tank cleaning service for petrol fillingstations storage tanks
EQUIPMENT
For works at petrol filling stations we use tank cleaning complex
JetPetroClean developed by DONTAL
Tank cleaning unit JetPetroClean
Hoses and ducts kit
External diaphragm pump
External fan
Personal protective equipment
Complex equipment is mounted inside a standard 20F container
For complete mobility the container could be mounted on a truck and
equipment may be used from the truck without the unloading the container
Total power of equipment is 77kW
Total dry weight of container is 6,6 t
Total weight of container filled with water is 12,8 t
If necessary, the amount of water can be reduced in order to minimize the
overall weight of the complex without having an effect on the tank cleaning
quality

TECHNOLOGICAL SCHEME
Internal washing will be carried out simultaneously by using a closed loop
technology, the nozzle, and the suction pumps
For internal washing we use fire water and, if necessary the industrial grade
detergent
The cleaning unit has the electrical water heaters which allow to heat water
up to +90 C and to use hot water for washing
In agreement with the customer also can be performed works of the internal
cleaning and degassing of the station piping
Degassing process is included into cleaning process and is a compulsory
part of all cleaning process
Degassing begins at the same time with the start of jet nozzle washing cycle
(while pumping out hydrocarbon residue), continued during forced ventilation
and will be finished on drying stage.

WORK SCHEDULE
Work can be done in two modes:
with interruption of the station and without interruption
In the case of interruption, the station is closed and works are executed on all
tanks at the same time. It allows reducing the total work time.
In the case of non interruption, works can be done only on one tank and other
tanks are in use. It allows reducing commercial losses due station interruption
Average time required for cleaning, degassing,drying and preparing for visual
inspection one tank is about 1..2 hours
This schedule does not include the time required for dismantling and back
installation of the tank manholes, which can be different in depending on the
condition of manholes and the degree of corrosion on fasteners
