UNDER WATER, not to blow

In order to avoid disaster to clean and repair the oil reservoir should be under water — not without reason to believe the inventor of Tomsk RL Buhtarenko

Leaky gas tank of the car. It would eka prodigy — poured gasoline, cleaning cloth yes podvaril place. Hardly syschetsya so quick to hand repairman. Rinse tank need to dry, blow, not the rest of it as gasoline vapors rush that you can stay without hands. But in the tank is only a few tens of liters of fuel was to drain. Well talk about an oil reservoir with a capacity of, say, six million liters ?!

In one case, there was such a «barrel» height of twenty meters without oil (drained before cleaning) for a long time, and once in the evening and exploded from spontaneous combustion. The roof — a steel pancake twenty meters in diameter — blown as cardboard, the housing wall at the top of torn like paper swatter. Day explosively releases, both from the volcano spewed flames high into the sky. Is that the lava and ash was not. Black smoke has carried out dozens of kilometers. And standing next to tanks full of oil. Heroic was the battle with the fire element. It was possible to create a water curtain and other rescue vessels. A demolition Burned piles of twisted metal fire lasted for many days.

In America, not so long ago exploded gas tank capacity of forty million liters. Before repairs, he was disconnected from the process gas, all connections plugged cavity and all of washed, steamed, purged air. The accident occurred in the midst of renovations, which were conducted both inside and outside. The reason remains unclear, as all 80 people were killed.

Of course, the oil-filled reservoir can catch fire, but empty — doubly dangerous. Even a timely precautionary measures do not guarantee, as seen in the last example, one hundred percent security. That water-filled tank at least spark chisel carving, though electric welding guns — no fire, no explosion will be.

Head of section of underwater engineering work of the Office of trunk pipelines in Central Siberia (Tomsk) RL Buhtarenko provides a method of cleaning oil tanks. After draining the oil reservoir is filled with water to its column was six to eight meters. Together with water from the bottom of the tank rises and oil residues and suspended solids and the suspension is formed, which is necessary for four hours to settle and separate into a solid sediment, clean water and crude oil above. While the slurry is separated into phases, the hatch-manhole, which is available in each tank, and is so called because through it people get through maybe parked gateway to it is connected pneumatic or hydraulic hoses to drive a variety of hand tools and electrical wiring for the lamp-carrying. The gateway comes diver removes the hatch-manhole and swims in a tank and bring the tools and lighting. After finishing work diver, leaving a reservoir of battens down a manhole.

The new method several advantages.

In preparing the cleaning tank need not be drained of oil through. You can merge only two-thirds, and the rest will be on the water column.

The reservoir is not necessary to wash, and steam thoroughly degassed, due to the large loss of time, and the oil that goes with the washing liquid and vapor.

Cleaning products can be removed through the hose connected to the scraper, without using the pump, by using only the hydrostatic pressure in the tank.

Unfortunately, airlock to fit over the hatch of the tank has been manufactured and tested method is not. Who was the first use of the invention, please inform.
