I would like to ask how to clean a tank
Thread Content
Who has experience in cleaning up abandoned containers containing residual oil (crude oil)? What is the procedure?
Crude oil is generally cleaned using high-pressure steam. Replace first, then clean.
Thank you first. How can residual oil and gas in the tank be removed to meet the requirements for welding inside the tank? Generally speaking, it takes two to three months for those odors to dissipate
Then it needs to be neutralized, washed several times, and blown out with steam. It is best to measure the oxygen content
First, drain all the crude oil from inside, then rinse it with water, and finally steam the tank! And it needs to be steamed for a long time, about 32 hours. It’s quite complicated; you should ask an operator from the tank area!
First clean it, then purge with air or nitrogen
We need to replace and neutralize DRAVON. Could you please explain in detail? Last time, we first used a sealed tank method followed by high-pressure water cleaning; after leaving the tank empty for two months, we entered it for just a few minutes before the smell became unbearable. Also, do you know how much it will cost to hire an external contractor? Thank you.
Reply to 7# Wall Street Storm: I’m not exactly sure about the specific teams involved; there are specialists outside who specialize in tank cleaning, and they have a lot of experience. Generally, cleaning tanks containing highly toxic substances costs around 3,000 to 4,000 yuan. That one needs to be cleaned several times; I’ve seen ammonia tanks require multiple days of cleaning before it’s possible to get inside them
