How to properly dispose of waste sludge

2020-08-15

Waste oil sludge refers to sludge mixed with heavy oil such as crude oil, various refined oils, and residual oil.

Oily sludge is not inherent in nature, but due to various accidents, improper operations, etc. related to crude oil and refined oil, such as oil field extraction, petroleum refining process, transportation, use, storage, etc. Oil and soil formed by mixing with soil, water, etc., caused by equipment obsolescence, damage, corrosion, etc., causing crude oil and product oil to run, spill, drip, and leak, leak to the ground, deposit in the ocean, lakes, and river bottoms, Water, even mixed with other contaminants.
For waste oil sludge, the current treatment methods include: conditioning treatment, hot washing, thermal oxidation, incineration, and preparation of flotation agents.
The above-mentioned treatment and disposal methods will produce waste gas, waste water, sludge and noise during the storage, treatment and disposal of oily sludge. For waste gas, currently, more companies use anaerobic cracking to treat sludge.
The working principle of the oil sludge cracking equipment produced by Lifeierte Shangqiu Branch: the oil sludge enters the cracking reactor through the screw feeder, and under the condition of high temperature, atmospheric pressure and oxygen-free, through different physical temperature sections, water, oil and gas, oil residue The separation of oil and gas is recovered through the cooling device.

The sludge produced after sludge treatment can be sold to brick factories to make bricks, or sold to oil fields as an anti-collapse agent for oil wells. Waste water and sludge need to be treated accordingly, and the remaining waste water and sludge must have a reasonable destination.
