How the Landing sludge, oil and gas station tank bottom sludge, sedimentation tank oily sludge made of?

The production of landing sludge

In the process of drilling and test injection of oil exploitation, a large amount of crude oil falls to the ground, mixed with soil, sand, water, and other substances, forming a mixture of oil and soil, called landing sludge; According to the nature of the falling crude oil, the mud can be divided into heavy mud and thin mud, and according to the length of stacking time, it can be divided into fresh mud and accumulated mud. The oil content rate of the oil mud on the ground can generally be 10-30%. Because all kinds of domestic garbage are available at the oil production site, the oil mud is mixed with glass bottles, mineral water bottles, convenience bags, gauze, and other household garbage, and other solid wastes in addition to soil and sand.

Oil and gas station tank bottom sludge generation

When crude oil is stored in an oil and gas station tank for a long time, inorganic impurities such as high melting point wax, asphaltene, colloid, and embedded mud sand in the crude oil will become sediment with water, forming oily sludge at the bottom of the tank and reducing the effective volume of the tank. This part of oil mud is called oil and gas station tank bottom mud.

Production of oily sludge in the sedimentation tank.

The waste oil of refineries, petrochemical plants, and other industries is usually directly poured into the large sedimentation tank, and the oil-bearing sludge produced by the sedimentation tank is called oil-bearing sludge.
