Oily sludge is a common byproduct of many industrial processes, including oil and gas production, refining, and petrochemical manufacturing. Oily sludge is a hazardous waste that can contain hydrocarbons, heavy metals, and other pollutants. Proper treatment of oily sludge is essential to minimize environmental impacts and comply with regulatory requirements.
There are several technologies available for the treatment of oily sludge, including:
- Thermal desorption: Thermal desorption is a process that involves heating the oily sludge to high temperatures in the absence of oxygen. This process vaporizes the hydrocarbons, which can then be condensed and collected. Thermal desorption is an effective technology for oily sludge treatment and can recover up to 95% of the oil content.
