　　Changqing Oilfield cleaning tank sludge non landing treatment equipment

　　Summary: Oil sludge is also known as oily sludge, oil sludge sand, and ground oil sludge. During the drilling process, the oily sludge brought out by the replacement and extraction of casing on the drilling rig will be left around the well site. These oily sludge are wrapped in various sediment and debris, which cannot be treated on site and are temporarily piled up in the well site. The more they pile up, the more they are produced. The oily sludge comes from deep in the drilling formation and contains a large amount of toxic substances such as benzene, phenols, anthracene, pyrene, etc., which have a foul odor. If the oily sludge is not treated, it not only damages the soil pollution environment, but also causes waste of resources. The generation and harm of oily sludge (oil sludge sand). In 2013, China required non landing treatment of oil sludge to prevent damage to the natural environment.

　　According to the standard of non landing treatment for oil sludge, our company has conducted equipment research and development and upgraded the existing equipment. Currently, our non landing treatment equipment for oil sludge has cooperated with dozens of environmental protection units for oil sludge treatment, and can provide practical cases for customers to observe on site. The following introduces the basic process and principle of the equipment for cleaning oil sludge without falling to the ground.

　　Application of equipment technology for cleaning oil sludge without falling to the ground:

　　At present, there are various treatment processes for oily sludge in the market, among which thermal desorption treatment and thermal desorption treatment are more commonly used. The thermal analysis treatment scheme for oil sludge adopts a closed high-temperature liquefaction gasification method, which has a relatively high energy consumption, difficult crude oil collection, low treatment efficiency (about 5 tons/hour), and relatively high treatment costs. The oil sludge thermal desorption treatment scheme has low energy consumption, low input, and high efficiency in crude oil recovery and treatment (about 20 tons/hour), making it economically efficient and easy to put into production. Currently, it has become a widely used oil sludge treatment scheme.

　　Ruichen Environmental Protection Company, based on the characteristics of oily sludge and relying on the technical advantages of solid-liquid separation integration solutions, combined with years of experience in the research and application of oilfield solid-liquid separation equipment systems, has launched this economically efficient "oil sludge thermal desorption treatment solution".

　　Step: Use sorting equipment to separate stones, weeds, tree roots, and other debris from oily sludge.

　　Step 2: Use heating tank equipment, mixing equipment, and dosing equipment to fully separate water, oil, sediment, and other substances through water temperature and chemical mixing, taking advantage of the different physical characteristics of oil-water density. The specific gravity of oil is small and attached to the upper layer, followed by the specific gravity of water in the middle layer, and the specific gravity of sediment is large and settles in the bottom layer.

　　Step 3: Utilize three-phase separation equipment, which can also be achieved through oil-water separation equipment and sludge water separation equipment. The purpose is to achieve three-phase separation of water, oil, and sludge, as well as crude oil recovery and water reuse. Mud and water enter the mud and water treatment equipment, and the water can be reused in the heating tank or further processed through the water treatment equipment.
