Methods and Techniques of Hazardous Waste Disposal

The proper methods and techniques to hazardous waste disposal is essential for citizens and business owners alike. Hazardous waste is defined by waste that poses significant or potential threats to the public, health, or environment.

Historically, hazardous wastes were regularly dumped into landfills. This unfavorable action caused the chemicals to seep into the ground and eventually enter our natural water systems. From there, our wild and marine life mammals became exposed to all sorts of chemicals which can in return cause issues for us.

The following are some Methods and Techniques of hazardous waste disposal:

1.The use of Incineration by burning the material in high temperatures is a great way to destroy toxic waste. Incineration actually destroys and terminates most HHW. A benefit of society using this method is the fact that the flammable wastes can also be burned and used as energy sources. The method of Incineration releases toxic gases which can affect the environment, but current technology has developed more effective incinerator units that limit the amount of emissions released in the sky.

2.Find out what hazardous waste collection facilities are in your area! Many times, communities will designate special days for collection. If you are in immediate need of proper hazardous waste disposal, you can contact your local government or head over to your local municipal building where they should be able to help you.

3.If you have diabetic syringes or prescription drugs, you should be very careful about how you dispose of them! Most pharmacies carry a mini disposal box where you can throw away used syringes. Prescription drugs should always be handed off to a drop-off location! They should never be thrown in the trash or flushed down the toilet or sink!

4.To share it! For instance, if you have extra oil or fertilizer lying around you can share it with a person who is need!

Hazardous waste management methods

Hazardous Wastes Management:Hazardous wastes that need management or disposal may be freshly generated from an industrial operation, they may be old stored chemicals, or they may have been sitting in a dumpsite for many years. At a dumpsite, component chemicals difficult to identify, they are likely to have reacted with one another, and they may have already affected the surrounding soil and water. Land disposal and incineration are two main dumpsite remediation methods. Types of waste treatment include physical, biological, and chemical neutralization or stabilization.

Hazardous waste management
Hazardous waste management

Industries in the United States dispose of about 60% of their hazardous waste using a land disposal method called deep well injection. Liquid wastes are injected into wells located in impervious rock formations that supposedly keep the waste isolated from groundwater and surface water. Unfortunately, hydrogeologists now predict that groundwater flow actually does occur in most previously-designated impervious rock formations, and injected waste often migrates into groundwater reservoirs called aquifers. Other underground burial locations for hazardous wastes include deep mines, natural caverns, and man-made deep pits.

Landfilling is the other primary land disposal method for Hazardous Wastes Management in the United States. Hazardous waste landfills are similar to regular solid waste landfills, but they must meet much higher standards for safety and environmental protection. The EPA requires that most hazardous wastes be treated before being discarded in properly-designed, approved landfills and burial sites.

Incineration, or burning, is a controversial, but still common, method of Hazardous Wastes Management. The EPA estimates that five million tons of hazardous wastes are burned each year in the United States. Various incineration technologies exist for a variety of types of waste. For example, volatile chemicals like paint thinners, oils, and solvents are destroyed by combustion at cement plants whose furnaces, called kilns, reach temperatures of 2,700°F (1,500°C). Needless to say, residents living near cement plants and other hazardous waste incinerators often have concerns about air pollution. In 1993, the EPA tightened its regulations on emissions from most hazardous waste incinerators, including cement kilns, after discovering that the emissions contained like dioxins, furans and other substances that cause cancer and other health problems in humans. Another recent EPA study noted that medical waste incinerators that many hospitals use to burn hazardous wastes also emit dioxins.

What is the newest technology in drilling waste treatment?

The main components of the drilling waste are cuttings, excess drilling fluids, hydrocarbons and water and are mostly categorized as hazardous waste. The disposal of these wastes are, in most locations around the world, highly regulated. The solids in the drill cuttings are usually separated and the cleaned off drill mud residue, as well as the produced water are usually cleaned at considerable costs.(drilling waste treatment)

drilling waste treatment equipment

The first step in managing drilling wastes is to separate the solid cuttings from the liquid drilling mud. Once solid and liquid drilling wastes have been separated, companies can use a variety of technologies and practices to manage the wastes. For some applications, drilling wastes are solidified or stabilized prior to their ultimate management practice. The management technologies and practices can be grouped into three major categories: waste minimization, recycle/reuse, and disposal.

The Following information is more about the drilling waste treatment equipment

Vertical Cuttings Dryer( Vertical Centrifuge) can perform solid/liquid separation through centrifugal separation. The vertical cuttings dryer can effectively recover the liquid phase in drilling cuttings, making the solid phase become very dry. It is suitable for water-base mud, oil-base mud and synthetic base mud. By recovering the mud in drilling cuttings, the vertical cuttings dryer can reduce the drilling cost and cut down environmental pollution. With handling capacity of 40-60 T/h, the oil on cuttings (OOC) of drilling cuttings can be reduced to lower than 5% (w/w) after treatment, meeting the international emissions standards and environmental protection requirements. The vertical centrifuge can also be applicable for drilling waste management in onshore and offshore drilling.

-DC Series Decanter Centrifuge is used in separating suspension of solids phase with particle ≥2μm in diameter for drilling mud and fluids handling.

-Screw Pump is an ideal pump used to feed drilling fluids to decanter centrifuge since drilling fluids is pushed to proceed along axial direction evenly. Therefore, the inner flow speed is kept low, volume unchanged and pressure stable so that vortex and agitation are prevented. Screw Pump is useful for wet mud drilling mud waste management and cuttings transportation.

Screw conveyor (Auger) can be used in drilling waste management projects, providing an effective and low-cost drilling cuttings transport system for offshore and onshore drilling rigs. Adopting a multi-sectional composite structure with each section of 12 feet (3.66m), the screw conveyor can be flexibly assembled on different drilling sites, with characteristics of simple operation, stable structure, strong adaptability and high safety, significantly improving the operating efficiency of equipment and reducing the cost and resources. The flights of screw conveyer adopt wear-resistant material to ensure its service life.

Hi-G Dryer is used to recover the mud from drilling cuttings,so as to reduce the liquid/oil content in drilling cuttings to as low as about 10%(w/w) and recover part of the drilling mud,so that the drilling cost can be reduced and the drilling waste volume can be cut down,for the purpose of reducing environmental pollution.The Hi-G dryer suitable for both of WBM and OBM.

Kosun solids control undertakes equipment selection, design and manufacturing according to material data and actual demands of users. We warmly welcome users to visit our Company for field investigation, technical exchange and long-term cooperation.

What’s the Solid Control System consist of?

Kosun as the professional solid control system manufacturer, we have our own understanding about this system.In Kosun’s words, solid control system is also called drilling fluids purification system, primarily applied for solids control and solid-fluid separation in drilling fluids so that the drilling mud might be recycled. Consisted of 3-7 module composite tanks and configured with 4 phases of purification equipment, it is fit for 2000-7000 meter oil drilling processes. The whole system is innovative with the bottoms of its purification tanks made to be conical and its edges equipped with mud agitating system to prevent solids from depositing. Besides, its tanks and bins may be comparted or united depending on the demands of drilling processes. Each of them is connected to another via pipe network in which the valves at the bottom of suction pipes are flexible while being opened, but can turn to be a good seal when closed.

What’s the  Solid Control System consist of?

Solid Control System

The first main equipment for solid control system should be the vacuum degasser,We could analytics from the function of vacuum degasser. Generally speaking, horizontal vacuum degasser will be used to separate the gas from the drilling solids. What’s the reason to do like that? Because we should do everything to prevent any dangerous elements in oil & gas drilling fields. That’s why we should put the vacuum degasser as the first role.

The second one should be mud cleaner. KOSUN MD Series Mud Cleaner is the second stage separation equipment for drilling fluids, which deals with the mud being treated by the first grade separation equipment. The barite will be recovered and cuttings which are bigger than barite will be removed. Then the barite in the underflow will flow into circulation tanks through the screens when the weighted mud passes while the particles that are bigger than mesh will be removed.

The third equipment, we think it should be shale shaker (with necessary steel frame shaker screen). Actually, after the drilling solids have been transported and fed into vacuum degasser and mud cleaner, the third step is going with shale shaker. Commonly, we still need to be transported the solids onto the shale shaker, or we could say onto the surface of shaker screen. The equipment of transporting we should use is centrifugal sand pump or screw pump; and we may use shear pump to cut the drilling solids into small one if they are in big size. With the different design of the shaker screen’s mesh, we could get the drilling solids separated in different sizes.

The fourth equipment should be the decanter centrifuge. KOSUN DC Series Decanter Centrifuge is used to separate suspended solids ≥2μm in diameter and treat the drilling mud and fluids. It is especially effective when used in oilfield service industry, industrial service industry and especially in environmentally sensitive areas. This type of centrifuge is high in recovery rate, effective in solids control and remarkable in the reduction of cost spent on drilling mud resupplying and management. It is a very sophisticated dynamic balancing machine, able to operate stably with the whirling speed ranging from 0 to 3900 and generate centrifugal force of 3000G. In solid control system, decanter centrifuge has been popularly used, which is also the popular one for drilling waste management. In this step, we could not only get the result of separating, but also we could separate the oil from the drilling solids, even if the oil is just a little part.

Of course, the whole equipment must be mounted on the top of drilling mud tank, which is a kind of basic equipment for both solid control system and drilling waste management (vertical cutting dryer is the core equipment for this system), but it is a kind of powerful equipment.

Cutting Dryer very Popular all over the World

Cutting Dryer

Vertical cuttings dryer use the centrifugal force to separate the oil from the drilling cuttings generated during oil extraction process from an oil well. The drilling cuttings are the waste product generated in large volume in drilling operations.
They are gaining popularity worldwide due to their capacity to separate oil from the solid waste that could be measured as ROC (retained oil on cuttings) or OOC (oil on cuttings). They are said to recover as much as 15% of the volume of the total waste. This not only saves the environmental damage but results into unintended loss of oil and economy of operations.

cutting dryer
cutting dryer

The way a vertical cutting dryer works could be understood in these simple steps –
A.    The drilling waste is churned using centrifugal force generated by mechanical rotation that results into separating of oil from solid.
B.    The drilling cutting generated solid waste is eliminated using sieve basket and scrapper.
C.    The liquid thus extracted is carried through pipes to a separate tank for further treatment and solid remains in the basket
D.    Then the dried solid waste is discharge to a separate container for further disposal.
The drill cuttings thus separated by cutting dryer from drilling liquid forms large part of the drilling waste and needs to be disposed off safely to prevent the contamination of environment.
Drilling waste treatment was not given much importance in earlier period when drilling operations came into existence but the scenario changed rapidly off late beginning early 1980s in wake of damaging impact of un-thoughtful disposal methods used by companies. The oil and gas industry has become more aware of their responsibility toward the environmental wellbeing thanks to number of protests by local people where such damages were evident and intervened by regulatory authorities thereafter.
Since then the technological advancement has played significant role in improving the drilling operations and their environmental footprints. Vertical Cutting Dryers are one such significant development in that direction.
