KOSUN provides oily sludge treatment systems for oily sludge generated during oil and gas production, oil gathering and transportation, crude oil storage, and refining.
What Is Oily Sludge?
Oily sludge is an industrial solid waste generated during oil and gas production, storage, transportation, and refining. It typically contains crude oil, water, and inorganic minerals.
Due to its complex composition, oily sludge can contain water-in-oil (W/O) and oil-in-water (O/W) phases, suspended solids, and high-viscosity components. These characteristics make oily sludge difficult to settle and treat, while its sources and composition can vary significantly.

Environmental Concerns of Oily Sludge
Untreated oily sludge can occupy large amounts of land and may cause pollution to surrounding soil, water, and air. It can also generate unpleasant odors and contain microorganisms, parasites, heavy metals, salts, and other persistent hazardous substances.
Proper treatment is therefore important for reducing environmental risks and improving the management and recovery of oily sludge.
