Heating and chemical washing treatment of oilfield oil sludge and oily waste

BY admin 25 September 2022 Drilling equipments Company, Drilling Waste Management, Oil Sludge processing system, Uncategorized

If the oil sludge discharged from oil sludge treatment is directly discharged without treatment, it will not only occupy a large amount of land, but also contain a large amount of heavy metals and bacteria, which will produce foul odors and cause serious pollution of water, soil and atmosphere.

At present, there are many treatment technologies for oily sludge, in accordance with the requirements of reduction, harmlessness, resource utilization and comprehensive utilization.

The main treatment methods of oily sludge waste in oilfields are as follows:

1. Incinerate in a high temperature incinerator. Oilfields often use thermal desorption unit (TDU). The sludge is incinerated to recover clean oil and water, and the oil content in the solid waste is reduced to less than 0.5%. The products that meet the standard will be landfilled or fired bricks. This treatment method is costly and causes coking, which affects the normal operation of the incinerator. And energy cannot be recovered efficiently. If the oily sludge has a high moisture content, the temperature in the incinerator will decrease after entering the incinerator, and the pollutants after incineration will not be able to reach the standard stably, which will lead to air pollution and dust pollution.

2. Treat oily sludge by drying ordinary sludge. Because of the particularity of oily sludge, common processes and machines are not suitable for the treatment of oily sludge, which leads to agglomeration and coking of oily sludge in the equipment, making the equipment scrapped. In addition, the oily sludge treated by the ordinary sludge drying process cannot meet the standard. For example, equipment such as rotary kiln sludge dryers will form coking inside the equipment in a short period of time during the process of processing oily sludge, causing the equipment to fail to operate normally.

3. GN Solids Control Use chemical hot washing to treat and recycle oily sludge. As far as China’s current situation is concerned, chemical hot washing is mostly used for oil recovery from oil sludge, with the purpose of recovering oil. Therefore, the oil sludge after hot washing is a non-standard product and still needs to be treated. Therefore, the hot washing method can only be used as an auxiliary method for reduction, and cannot be used as a direct oil sludge treatment method.

Transmission structure of drilling mud agitator

BY admin 12 September 2022 Uncategorized

The transmission structure of drilling mud agitator is mainly composed of driven motor, reducer gearbox, connecting device and mixing shaft assembly. There are not many forms of drilling fluid agitators commonly used in drilling fluids solid control systems. Among them, there are worm gear direct transmission and worm gear coupling transmission.

Mud agitator is used at trip tank, pill tank, desilter tank, mud suction tank, mud reserve tank, mud mixing tank. It is also used under the decanter centrifuge to avoid the mud settle down.

Mud agitators are normally used together with mud guns. Normally a mud agitator with a mud gun. The mud gun is used to support the 4 corners of mud tanks. GN Solids Control mud guns have 3 nozzles. Each nozzle]of GN mud gun can cover 120 degree, the 3 nozzles can cover totally 360 degree of the mud gun. The mud agitator is driven by electric motor. While the mud gun is driven by centrifugal pumps which are used for mixing or mud discharge.

Some manufacturers have also used worm gear and worm coupling drive. Worm gear drive is widely used in drilling fluid agitator due to its simple structure, large speed ratio and high reliability. Early drilling fluid agitators were almost all directly driven by worm gear. Although the worm gear coupling drive and belt drive are large in size, they have the characteristics of soft motion, which is good for protecting the overload of the motor. Therefore, some manufacturers will choose them.

The most commonly used agitator transmission mode is the gearbox reducer. The advantages of gear reducer agitator are high transmission efficiency and less maintenance. The disadvantage is large volume. Gear driven agitators are also divided into direct drive and coupling drive. The direct drive mud agitator is the most commonly used agitator drive form at present because of its simple structure and convenient maintenance.
