Water-base Mud Zero Discharge Treatment

Water-base Mud Zero Discharge Treatment Operating principles:
Water-base mud cuttings enter the top hopper of vertical centrifuge and fall onto its internal separation area. The internal cone rotates at a high speed of 900RPM and generates a centrifugal force of 430G. For density difference between liquid and solids, mud is hurled out of surface of drilling cuttings and passes through screens, and solids are retained inside the screens. And then, liquid is discharged from the liquid outlet and dry solids are discharged from the bottom of equipment.

Water-base Mud Zero Discharge Treatment

How pyrolysis plant assistance to treat oil sludge?

How pyrolysis plant assistance to treat oil sludge?

With the invention in the oil sludge treatment pyrolysis plant, it is sometimes complicated to deal with oil sludge. Oil sludge results as by-products of drilling and oil refinery and is a variety of water and oil. The oil sludge pyrolysis plant helps you to separate water and sludge from oil making the oil in the sludge usable again. In reality, pyrolysis plants can produce high-quality fuel oil. Oil sludge recycling pyrolysis plant consists of a reactor, hydroseal, oil condenser, oil tank, and de-casting system.

The Oil Sludge Design Treatment Plant:

-The principle aspects of the exhaust gas, which cannot be liquefied, include alkanes class c1 to c4, whose direct burning poses a lot of danger. The system is made to pass these gasses first through water seal, that happen to be contain inside the first seal devices before burning them as fuel after which undergone a gas burner that is within a second safety device.

-The machine includes hydroseal that really help to stop the fire burning back since they remove sulfur, impurities and make cleaning desulfurization gas.

-The system is built to include specific operating tech that helps to handle bugs during production.

-It really is designed to feature a specialist thermometer and pressure gauge that really help to examine temperature and pressure.

-It used the third generation heating way in which combines the main advantages of direct and indirect heating to ensure safe operation.

Oily Sludge Management
Oily Sludge Management

Oil sludge treatment plant can be found in three types, that include batch oil sludge, half automatic oil sludge plant and fully automatic oil sludge pyrolysis plant. The best type for you personally depends upon your requirements and your budget as they are intended for different prices. Crude oil sludge pyrolysis recycling plants are highly beneficial, and their prices cannot complement the main advantages of oil sludge properly.

Oil sludge is caused by exploration, drilling, and refining of oil resources. It composes of oil, water, and sludge, which can cause an increased polluting the environment when they’re not processed. However, oil sludge features a great deal of oil, which is amongst the most pressures resources and may give a home business opportunity. Beneficial to our environment oil sludge treatment plants happen to be designed to treat the environmentally unfriendly oil sludge into treasured oil products. (Editor:Kosun Lily.Wang)

Environmental Oil sludge treatment

Environmental Oil sludge treatment – Electric radiant heat analysis process

Thermal analysis: after Oily sludge pretreatment to achieve material uniform and most of the water can be separated, purification and discharge. The remaining residue continuous delivery to the rotary reactor through the feeder. Before the material enter into the reactor, the strong magnetic sucker above the conveyor will suck the metal debris. After into the reactor, the reactor drive motor embedded in a special shape of the blade, the rotation of the shaft, so that the material in the reactor to achieve rotation Back and forth exercise. Solid material imports and residue exports are composed of two pneumatic valves, the reactor is under a slight positive pressure, and adopted a special sealing technology to prevent intermittent feed and air leakage into the system to ensure that the system is running Security.

oil sludge treatment

All system high-temperature area are electrically heated, the reactor operating temperature is generally 400-480 ℃, so that the material at a suitable temperature decomposition. After entering the reactor, the solid phase material is heated and dried to evaporate water. The dried solid phase material stays in the reactor for an appropriate time. The organic pollutants in the solid phase are heated to the boiling point to evaporate from the solid phase.

Condensation separation: The gas generated by the decomposition is firstly dedusted by the ceramic filter, then enters the counter-flow tube condenser, the condensate is recovered at the bottom of the column, the condensate enters the water treatment device for oil-water separation, filtration and purification, and the moisture is reused for treatment After the cooling and humidification of the dry material, the separated oil can be recycled; uncondensed gas is discharged from the top of the tower, after filtering cotton, induced draft fan, oxygen indicator, the gas volume flow meter and then back to the reactor Burning heat.

Several Oily Sludge Management technologies

At present, the total amount of oily sludge produced in our country has exceeded 500 million tons every year, and the output also shows an increasing trend year by year. Oily sludge mainly from the following three aspects.( Oily Sludge Management)

Oily Sludge Management
Oily Sludge Management

(1) crude oil extraction process. Crude oil production process will produce a amount of oily sludge. The sludge produced mainly from the oil recovery wastewater treatment, the sedimentation caused by the added water purifying agent and the crude oil produced by drilling.

(2) Oil gathering process. Oil gathering process will produce a amount of oily sludge. Transfer stations and joint station tank sludge, sedimentation tank sediment, grease trap sediments are all oily sludge. Oil sands produced from natural gas purification plants and sludge are also oily sludge.

(3) Sewage treatment plant. Oil refinery wastewater treatment plant will also produce oily sludge, mainly from the biochemical pool of excess sludge, grease trap sediment, flotation tank scum, crude oil tank sediment.

Several Oily Sludge Management technologies

Oily sludge must be treated as it is detrimental to the environment. At present, there are several commonly used methods for the treatment of oily sludge in our country: incineration, thermal desorption, landfill, etc. In addition, there are biological treatment, coking and chemical heat washing.

oily sludge treatment

In response to the requirement of resource-based, harmless and reduction of oily sludge treatment in our country, there are many new oily sludge treatment technologies emerging such as ultrasonic treatment of oily sludge technology, cement sludge co-treatment of oily sludge technology and Solvent extraction processing technology.

The source, composition, characteristics and nature of oily sludge in oilfields all over China are different, so the technology applied to oily sludge management is not the same. Therefore, the oil field in the selection of oily sludge treatment technology should be based on the advantages and disadvantages of various technologies and the scope of application. Combined with their own circumstances choose a reasonable technology.(Editor:Kosun Lily.Wang)
