What is Oil Sludge and how to defend it ?
What is Oil Sludge?
Into the tank when pumping or pumping out a product, air enters through a ventilation pipe, which is designed to prevent overpressure in the tank. Water vapor from the air condenses into droplets and settles on the walls of the tank, causing rust. Water with rust particles settles at the bottom of the container, mixing with the oil. In this environment, microbes appear that feed on the oil, as a result of which the oil breaks down, forming a sediment called – “Sludge”
How to clean oil products from Sludge?
In most cases, three methods are used to treat oil products from sludge
- Reducing the formation of sludge through the use of special technologies.
- Recovery of oil from sludge.
- Removal of unrecoverable oil sludge.
The first method is considered to be preventive and is designed to prevent the formation of sludge. The next two are aimed directly at effective treatment of the crude oil sludge.
Some of the methods employed in recycling hydrocarbons from petroleum sludge are:
- Froth flotation
- Ultrasonic radiation
- Electromagnetic method
- Microwave radiation
- Sludge pyrolysis
- Frost and melt treatment
- Surfactant enhanced oil recovery (EOR)
- Centrifugation treatment
- Solvent extraction
