Novelty of the developed by the specialists of "Pure World M" ("Чистый Мир М") washing station railroad tankcars is to replace the long hours of steaming car washing on the inner surfaces of the tank by technical detergent of the new generation.
The site fro processing tanks at two posts include a flyover, mobile complex MKO-1000, pushing container of 50 m3, a container for the eroded hydrocarbons, heat exchanger for heating the technical detergent of the new generation. Heat energy site is supplied either from the central heating unit or the individual miniboiler on isothermal oil.
The inner surface of boiler tanks treated with hot jets of aqueous solution of 0.75% weight concentration. The solution temperature is maintained between 65 - 80°C, solution flow rate through the jet nozzle washing machine is about 18 m3/h at a pressure of 8 kg/cm2. While blasting the tank depends on the amount of bottom sediments. The cleaning solution used on the back of the circuit. With the help of mobile cleaning complex of the company "Pure World M" MKO-1000, mounted in a 40-foot container, consisting of 2 tanks for a working solution with a volume of 25 m3, pressure pump capacity of 38 m3/h at a pressure of 10 atm.
Grappled flushed tanks supplied to the engine of the viaduct, where workers set on neck tank universal technological cover with reinforced them washing machines and devices to drain tanks attached devices underflow with telescopic jetting. Thereafter, the tank is fed the cleaning solution concentration of from 1.5% to 2.5% being the inner noncontact jetting. The emulsion is pumped to the shunting capacitance, where it is separated to hydrocarbon fractions and detergent. After heating in the heat exchanger, the cleaning solution is returned to the setting unit with a capacitive feed to the next wash cycle. Washed residues of hydrocarbons from the separation module periodically pushed to the collector, and then implemented as a commodity product. Hard deposits (slime) undergo recycling by known techniques. Drying the tank by high pressure fan, heating the air carries steam (oil) heat exchanger.
For drying and degassing after washing required 30-40 min. And the total processing time of the tank is from 2 to 4 hours, depending on the degree of contamination and the time of year.
Movement of cleaning solution is provided in a vicious circle:
expenditure container of technical detergent -> washing machine -> the collection and recovery of bitumen-water emulsion from the tank through the installation of underflow in the collection of the cleaning solution -> flow separation on the washed out oil sediment and the initiated aqueous solution -> heating of the cleaning solution and feeding it by the pump to the washing machine.
