Oil sludge is also called oily sludge, oil Sludge sand, ground oil sludge and so on. during the drilling process, the oily Sludge brought out by the drilling rig when replacing and extracting the casing Is left around the well site. the oily sludge is wrapped in various sediments, Etc., which is too late to deal with and is temporarily stacked on the well Site. but the more piles, the more it is produced. the oily sludge comes from Deep in the drilling stratum. the oily sludge contains a lot of benzene series, Phenols, anthracene, pyrene and other odorous toxic substances. If the oily Sludge is not treated, it will not only Destroy the soil, pollute the Environment, and cause a waste of resources.

 There are many domestic oily sludge treatment Processes, among which sludge thermal analysis treatment and sludge thermal Desorption treatment are more widely used. The sludge thermal analysis Treatment scheme adopts a closed high-temperature liquefied gasification method to process, which has high energy consumption, difficult crude oil collection, Low treatment efficiency (about 5 tons/hour), and relatively high treatment Costs. The sludge thermal desorption treatment scheme has low energy Consumption, low input, crude oil energy recovery, high treatment efficiency (about 20 tons/hour), cost-effective and easy to put into production, and it Has become the most used oily sludge treatment scheme.

Based on the characteristics of oily Sludge, relying on the technical advantages of the integrated solid-liquid Separation solution, combined with years of experience in the development and Application of oilfield solid-liquid separation equipment systems, Kinway Energy Launched this cost-effective "sludge thermal desorption treatment Program".

through the sorting equipment, the stone, Weeds, tree roots and other debris in the oily sludge can be sorted.

through heating tank equipment, mixing Equipment, dosing equipment, the use of different physical properties of Oil-water specific gravity, through the water temperature and pharmaceutical Mixing to fully stratify water, oil, sediment, etc. the proportion of oil is Small and attached to the uppermost layer, the proportion of water is second to that of the middle layer, and the proportion of sediment is heavier than the Bottom layer.

Using three-phase separation equipment, this step can also pass through oil-water separation equipment and mud-water Separation equipment. the purpose is to realize the three-phase separation of Water, oil and mud and the return of crude oil and water reuse. the muddy water Enters the muddy water treatment equipment, and the water can be reused in the Heating tank or further processed by the water treatment equipment.
