Shearforce Process…the Solution

Oil/Water Cleaning

Shearforce rotors do not have vanes and thus have specific advantages over conventional impellers and are better suited for certain applications.

These applications include entrained gas (air induced fluids), high viscosity fluids and fluids with high solid content.

The Shearforce pump plays an important role in the bio-remediation process by pumping air, solution, and solids, a three phase solution. The air creates millions of microscopic droplets and assist with solid separation from the hydrocarbons.

The pumping action prevents fluids such as oil from emulsifying.

The Problem: Crude oil tank bottoms contain settled inorganic particles which create a very tacky sludge at the bottom of storage tanks or when placed into sludge pits.

The use of SFACL (asphalt crude liquefier) liquefies asphaltenes and paraffin oil without the need of large amounts of equipment or personnel. This process turns the sludge into a pump able and sellable commodity.

Shearforce Sludge Processing

The Solution: The solution is to inject an all-natural SFACL biodegradable solvent which is allowed to penetrate the crude over a 24 hour period. Once the asphaltic crude is liquefied, the crude is pumped to a skid tank for screening where it is stored for off-site transportation.

The Application: The Shearforce Conditioning Process of spraying the chemical solution into a crude sludge at a very low pressure. This physical application requires very simple equipment without high pressure applications eliminating potential danger to the operating personnel.


The Effect: The picture below shows the liquefying of the sludge. This application is designed to create a solids suspended slurry or a very pumpable sludge that will not stick to the interior of hoses or downstream containment once it is removed from a tank.


The Result: The now pump able liquid recycled crude is pumped from the pit into a skid tank for screening of small debris. Sludge pits can be cleaned at a rate of 300 m^3 per day.

The crude is stored in skid tanks until offsite transportation is arranged.


The recycled crude has similar characteristics to number 6 fuel oil with a flash point of 136 degree Fahrenheit.

This crude can be blended with 5% diesel fuel allowing the product to be stored for long periods of time.


Treatment of Sludge “IN SITU”

OPERATION- Sludge Pits/Oil Storage Tanks

Procedure: The sludge will be treated by spaying the sludge with SF-ACL using a low pressure pump from a water truck. The SF-ACL is used at a rate of 6% to 10% of thevolume of sludge to be treated.

The SF-ACL will be allowed to penetrate the sludge for a 24 hour period. A Vacuumtruck or a floatable small barge equipped with the SF950 pump will be used to pump thenow liquefied sludge into a receiving/filter tank.

The run off will be further cleaned through the use of additional filter tanks or through thehydro-cyclone separator. The now clean fluid will be pumped through a density separator to separate the water from the now fuel oil. The fuel oil will be pumped into tanker trucks for shipment. The oily water and sludge sand will then be treated with SF1000 using a SF-1000.

Treatment of Sludge “IN SITU”

OPERATION-

CONCLUSIONThe SF ACL will liquefy the sludge in less then 24 hours. SF1000 will reduce the TPH levels of the remaining sand to less then 1 % in 2hours.

BACKGROUND:Bioremediation is the process of encouraging the natural process of biodegradation to cleanup spills and other environmental problems caused by humankind’s activities. There are three different types of bioremediation: nutrient enrichment, seeding with naturally occurring microorganisms, and seeding with genetically engineered microorganisms.

Shearforce experience with the cleaning of drill cuttings in Nigeria using the nutrient enrichment process of SF-1000 has demonstrated that there is a diverse enough indigenous population of oil-degrading microorganisms in the soil to carry out the bioremediation process.

Populations of oil-degrading microbes in most environments are limited by the availability of hydrocarbons. Following an oil spill, this limitation is overcome and the microbial population expands. In order for this to occur, the microbes need oxygen for respiration and other nutrients that are not available in petroleum.

Oxygen is assured by the use the Shearforce Pumps which added millions of microscopic air bubbles by injecting air into the suction of the pumps.


BACKGROUND:

Oil provides a rich source of reduced carbon, but no readily available nitrogen or phosphorus. These nutrients are vital to the growth of microbes. Nitrogen is essential for the synthesis of proteins and nucleic acids and phosphorus is vital for nucleic acids, and the energy metabolism of the cell. Some bacteria can fix nitrogen from the atmosphere, but this is not widespread in oil-degrading microbes.

Thus, the growth of oil-degrading microorganisms is limited by the availability of nitrogen and phosphorus. SF-1000 provides these nutrients assuring the goal of the bioremediation process.


Land Bioremediation: After the heavy sludge has been removed from an earth pit, a second chemical SF-1000 is sprayed into the the contaminated soil to further breakdown the crude. SF-1000 is a synergistic blend of synthetic surfactants which emulsify the hydrocarbon contaminants into microscopic droplets. The emulsion is easily biodegradable by naturally occurring micro-organisms (microbes). SF-1000 provides nutrients which create an immediate stimulation of the indigenous microbes (bacteria) and provide an immediate food source when tilled into the soil. This food source promotes the growth and metabolic activity of the micro-flora present.

A Track hoe is used to rack in and mix the hydrocarbon contaminated burns with the oily pit sludge. The loose debris is placed into the pit for treatment as compose material.


The Result: . Fresh soil is used from the surrounding area for stabilization material as well as additional source of indigenous bacteria. This process produces optimum condition for natural bioremediation.

The land is then suitable for farming or other use.


Water Bioremediation: Oily water will be present after the oil has been separated from the sand either from sludge pits or oil spills.

The process of cleaning the oily water is similar to that of oily soil. SF-1000 is mixed into the the contaminated water to further breakdown the crude.

The process may be enhanced by the use of heated water in the case of heavy oil/water emulsions.


Soil and/or oil samples are collected by a grid sampling method for an on site TPH analysis.

The TPH level of 200,000 ppm is dramatically reduced to acceptable levels of 5000 ppm with 24 hours. Further reduction in TPH level’s will be obtained after an additional 48 hours due to the drying and bio-degradation of the hydrocarbons.


OPERATION-Oily Soil

Procedure: The soil will be cleaning by a tilling method using an excavator or loadedinto SF washing tank using a 1 m^3 front loader. Once in the washing device SF1000 will be added along with water.

The soil will receive a 20 to 60 minute wash depending on the background reading of the contaminated soil. After the washing cycle, the DC will be placed in a designated DC clean area or removed from sites using dump trucks for deposit elsewhere.

The SF1000 will be mixed at a ratio of 1 ½ parts of concentrate to 10 parts water. One and one half gallons of SF1000 is required for 1 m^3.Each wash is approximately 10 cubicmeters of contaminated media. Before being discharged there will be a TPH reduction of approximately 93 to 95% upon completion of the wash cycle.

When the media is discharged, it should be placed in an area for additional drying and thebio-degradation of the hydrocarbons will continue without additional handling. A final analysis will be taken 48 hours upon completion to determine the reduction in the TPH.



OPERATION-

CONCLUSIONSF1000 will reduce the TPH levels to less then 1 % in less then 24 to 48 hours while being handled only once. The bi-product that is left can be used as road base or sold as materials for brick making.

OPERATION-Oily Water

Procedure: Flotation protective oil booms must be laid out to contain the oil spill andprotect from the potential spreading of the contamination in the water.

Samples of the contaminated water should be taken to establish background TPH. A vacuum truck should be utilized to remove as much free oil as possible, i.e. the oil floating on the surface. Once as much oil has been removed for salvage as can beexpected then the cleanup can begin.

By using flat bottom boats, two inch trash pumps fitted with two inch hoses and firenozzles, the media can be sprayed with SF1000. The chemical can be maintained in a 500gallon tank on the boats. As the chemical is sprayed there will be an immediate color change and all rainbows of the oil will dissipate.

The contaminated media (oil & water mixture) will need to be worked towards the booms orland so that the media can be reduced from spreading. The media will be pumped througha series of density separators then into frac tanks. Once in a frac tank dry ice will be usedto further separate the oil from the water. The oil will then flow through a weir section toallow the separated oil to flow out into salvage tanks.

Once the water has been cleaned the samples should be taken again to confirm theTPH levels.


Technical Explanation of Chemicals

The following is a Technical Explanation of Shearforce SF-ACL and SF-1000. Both are products offered by Texas Enviro Chem, Inc. which have been licensed to Shearforce Ltd. Both formulations are based upon compounds are totally bio-degradable.

ACL Properties

Shearforce SF-ACL is based on an anionic solvent, classified as an alcoholic solution of SodiumSulfonate CAS #68956-56-9. SF-ACL is a biodegradable terpene. D.O.T. (Department of Transportation)Hazard Class is # 3. The freight classification is cleaning compound.

Environmentally safe replacement for chlorinated hydrocarbon solvents Rapidly dissolves asphaltic or other harden petroleum products Blends with and becomes part of the liquefied petroleum product Reduces flash point of heavy crude’s to 135-145 degrees F Decomposition products are CO2 and water (biodegradable) Clear amber liquid Lavender odor 0.84 specific gravity @ 25°C >1.0 vapor density 320°F boiling point 108°F TCC Flashpoint 2 mmHg at 20°C vapor pressure

Shearforce SF-ACL creates a chemical reaction with the Sludge once it is sprayed and allowed to settle for 24 hours. This allows time to react with the sludge and become capable of being pumped into a transport truck or holding tank. By adding 6% by volume the SF-ACL becomes part of the oil which will not separate. The result is a burner fuel oil No. 6 (bunker C)with a flash point of 135 to 150 degrees F.


SF-1000 is a concentrated water based synergistic blend of biodegradable, non-toxic, non-flammable nonionic surfactants composed of Polycxyethylene Ethers: - Sodium bis (2-ethyhexyl) sulfosuccinate - CAS # 577-11-7. Classified as Alkoxylated Alcohols C10-12 ethoxylated propoxylated - CAS # 68154-97-2.

D.O.T. classification is non-regulated. The freight classification is a non-hazardous cleaning compound. It does not contain any enzymes or microbes.

The surfactant action of SF-1000 allows it to emulsify hydrocarbon contaminants into microscopic droplets suspended in solution. This emulsion solution remains stable in the rinse and/or treated media and plays an important role in the biodegrading of hydrocarbon contaminants since the emulsion is easily biodegradable by naturally occurring microorganisms.

Thus SF-1000 represents a food source that promotes the growth and metabolic activity of the micro-flora present. The net effect is an increase in the rate of hydrocarbon biodegradation. It is this methodology provides a multitude of benefits when using Shearforce SF-1000TM for spill response, in-situ bioremediation, water treatment or cleaning applications. Because Shearforce SF-1000 is a non-hazardous, non-flammable, water-soluble liquid, it can be used for removing oil and grease on surfaces while providing the following benefits:

Will not diminish the integrity of surfaces Very fast working (TCEQ-1005 TPH testing) Contains no ozone depleting solvents Non-toxic (EPA LC50 testing) Non-chlorinated Does not leave volatile or semi-volatile organics (EPA 8260B & 8070C tests) 100% biodegradable Provides odor control Promotes vegetation growth
