TECHNICAL FIELDThis invention provides economical, safe alternative compositions to many applications such as fertilizer, fertilizer additive, dust control, coating oil, freeze conditioning, oxidizer, and fire resistance. This invention uses generally a waste material comprising potassium mixtures in many commercial applications.
BACKGROUND OF THE INVENTIONPotassium is widely used as a nutrient promoting plant growth. It is needed to complete many essential functions in plants, such as activating enzyme reactions, synthesizing proteins, forming starch and sugars, and regulating water flow in cells and leaves. Typical forms of potassium fertilizers are potassium chloride and potassium sulfate. The present invention provides an alternative potassium source that is safe and economical.
Potassium acetate is a known deicing reagent applied by many industries and municipalities. For example, airports may spray potassium acetate to deice or prevent icing of runways. However, the selling price of potassium acetate ranks among the highest of all the deicing reagents marketed. There needs to be an economical alternative. The present invention offers an economic alternative.
Freeze conditioning agents (FCA) such as calcium chloride, glycols, glycerol, and sugar derivatives are applied in the coal industry to transload coal from rail cars in freezing weather. These products are costly, toxic, and/or contain chloride ie., sodium chloride. Sodium chloride is harmful to the environment and is corrosive. The present invention offers a safe, economic alternative FCA.
Dust control reagents currently marketed are mainly petroleum-based, or water solutions containing chloride such as inorganic salts. Inorganic salts are harmful to the environment and are corrosive. The present invention offers a safe, non-chloride based, economical alternative.
Other applications of the present inventions are described below.

DETAILED DESCRIPTION OF THE INVENTIONThis invention relates generally to methods and compositions of using an industrial waste in many applications. More specifically, the present invention relates to utilizing potassium mixtures generated from industrial processes including distillate residue or waste produced from natural fats and oils processing. The potassium mixtures are not regulated as hazardous materials, a benefit in its applications.
The potassium mixtures of the present invention comprise potassium acetate, potassium oleate, and potassium superoxide. Other components of the potassium waste stream consist of: glycerol, methanol, fatty acids, moisture, sodium, phosphorus, calcium, and/or magnesium.
It is known potassium acetate can be used as a fertilizer or fertilizer component. There are numerous commercial brands of potassium acetate fertilizers.
Potassium superoxide is an oxidizer—it can release oxygen promoting microbial growth in soil and fertilizers. This activity can promote plant growth.
Potassium acetate is also a freeze point depressant that can be used in freeze conditioning applications. Commercially available potassium acetate touts its application to deice airplane runways, bridges, or where there is sensitive environmental concern. Potassium acetate has excellent anti-icing and deicing characteristics, active at low temperatures (−20° F. and below). And is less slippery than glycol-based products.
Potassium acetate also has been used in fire extinguishers as an extinguishing agent. The present invention can be used to prevent fire by applying it to a combustible material including vegetations. Fire prevention refers to preventing fire or putting out fire. As an example, the potassium mixtures (diluted in water) can be sprayed on coal or vegetation to prevent or put out fire.
Other applications of this invention include dust control and coating oil of particles, solids, and fertilizers. The potassium mixtures are hygroscopic which aid in dust control. The potassium mixtures can be applied in grinding of particulates (including cement clinkers, mineral ores), drilling operations, and food preservation.
Dust control refers to preventing dust generation from handling of minerals or other solid particles, or from wind generation of dust particles. Dust can form from roads or other operations that generate dust. In an embodiment the potassium mixture stream is applied as a coating oil. Fertilizer pellets or granules and iron ore pellets can generate dust. To prevent dust or to improve particle or pellet flow, or to prevent stickiness or agglomeration, a coating oil is applied.
The present invention can be sprayed onto surfaces or particles, or dirt roads, where dust can generate. In embodiment about one pint to about one quart can be applied to a square yard of dirt road to prevent dust generation. The stream can be diluted from 10% to 1,000% with water by weight or by volume.
In an embodiment the potassium mixtures can be applied as a foam or mist. Surfactant can be added to foam the mixtures.
Methods and compositions for dust control and freeze conditioning are teach in U.S. Pat. No. 7,398,935, Tran et, al. The present invention can be apply to fine coal to prevent dust and to prevent its agglomeration, or icing together, in freezing weather. In addition, it can be applied to other particular material requiring similar treatment. The present invention can be applied to dirt or dusty roads, areas generating dust, piles or debris to prevent or mitigate dust.
Coating oil applications are teach in U.S. Pat. No. 8,163,059, Tran et, al. The coating composition may suitably be applied to any organic or inorganic particulate solid capable of caking or generating dust when disturbed, handled or processed. The present invention can control dust from particulate materials including farm products, corn, coal, wood chips, fertilizers, iron ore pellets, mineral ores, sand and gravel, cement, concrete, soil, construction debris, dirt and aggregates.
Typical fertilizers coating oil can be applied to include monoammonium sulfate (“MAP”), diammonium phosphate (“DAP”), trisuperphosphate (“GTSP”), calcium phosphate, ammonium nitrate, potassium nitrate, potassium chloride, potassium sulfate, and the like, and blends thereof. The fertilizer may be in granular, pelletized, crushed, compacted, crystalline or prilled form.
The potassium mixtures can be used as a grinding aid. Cement clinkers can be grinded using the potassium mixtures as a grinding aid. Water and/or other grinding aids commercially available may be added to the mixtures. Additives such as cement or concrete set time accelerators or set time inhibitors can be added to the mixtures. Mortar and/or concrete strength enhancement additive can be combined with the mixtures.
The present invention can promote microbial activity. Microbes can use the potassium acetate as a food source. Promoting microbial growth using the present invention can be applied to: research and development work relating to the health or pharmaceutical field; and treating waste, hazardous chemicals, or toxic chemicals. The present invention can be used to treat (including digestion and degradation of) industrial or municipal waste, liquids or solid waste.
This invention relates generally to methods and compositions of potassium waste stream that can be used in many applications. More specifically, the present invention relates to potassium mixtures generated as waste, or have minimum value, and using this useful waste in many applications. The benefits are providing economical compositions and reducing waste disposal, including eliminating handling, transportation and disposal costs. There are other benefits: These compositions do not have to be manufactured in typical, generally recognized commercial processes, that consume resources and perhaps pollute the environment.
U.S. Pat. No. 8,728,177, Jackam, et, al, teaches one industrial process that can generate the present invention potassium mixture waste. Production of fatty acid alkyl ester (FAAE) and glycerol from low-value high free fatty acid feedstock is described utilizing multiple steps or unit operations. This patent teaches a unique novel process utilizing many unit operations not used in other production processes of FAAE and glycerol. Another uniqueness is that it utilizes low-value high free fatty acid feedstocks for economical benefit, again not typically used by other production processes of FAAE and glycerol. Free fatty acids can impair production of of FAAE and glycerol, and the general industry practice is to utilize glyceride feedstocks containing minimum free fatty acids. Contemporary commercial process typically use feedstock that has a maximum of 15% free fatty acid. The patented process prefer to use feedstocks having up to 100% free fatty acids that are much lower in cost. Processing low-value high free fatty acids feedstocks requires unique unit operations.
Potassium methoxide is used as a catalyst in the production of FAAE and glycerol and ultimately the potassium becomes part of potassium mixtures of the present invention.
Production process teach in U.S. Pat. No. 8,728,177 utilizes distinguish unit operations that include a “reactive” distillation process, wherein the FAAE stream undergoes both physical separation and chemical reaction. To further purified the FAAE the stream undergoes a second distillation unit operation.
Other unique unit operations described in U.S. Pat. No. 8,728,177 includes utilizing wiped film evaporators in parallel, falling film evaporators in parallel, freeze crystallization, and glycerolysis reactor. And the process is continuous, not batch as typically practiced by other manufacturers. Other improvements discussed include generating a second FAAE and by-product streams, and purifying these streams using freeze crystallization.
Moreover, U.S. Pat. No. 8,728,177 describes a process using lower operating conditions (such as pressure) than other commercial production process. Waste is minimized.
The process as described above generates potassium mixtures. The mixtures and or its components can be generated from any of the unit operations. The potassium mixtures are concentrated and is referred to as distillate residue, bottoms material, and/or waste material. This waste stream, or minimum value stream, is the subject of this invention. It comprises potassium mixtures and other components.
List of possible components of the potassium mixtures include: potassium, potassium salts, potassium acetate, potassium oleate, potassium superoxide, ash, glycerol, methanol, moisture, fatty acids, sodium, phosphorus, calcium, and magnesium.
Concentrations range by weight of specific components are as follows:
It is noted that potassium is concentrated in the ash. In an embodiment the ash comprise potassium superoxide.
The potassium mixtures are highly viscous at room temperature. Pumping using normal means would be extremely difficult if not impossible. Heat is needed to transfer the potassium mixtures as is. The processor or manufacturer reports the potassium mixtures are partially miscible in water; however, upon continuous mixing with water, the mixtures can be solubilized - this is unexpected. For example, at about 60 (potassium mixtures):40 (water) percent by volume the potassium mixtures solubilized with stirring. Similarly, at 20% mixtures and 80% water by volume, the mixtures solubilized with stirring. Preferably three minutes or longer of stirring or mixing is needed. Filtration may be required to remove any solid particles remaining.
Physical characteristics of the potassium mixtures are:
It is important to note that when mixed with water (about 60% mixtures to about 40% water by volume) the freeze point of the potassium mixture-water solution is less than about minus 16° C. or 4° F. When mixed with about 80% water (about 20% potassium mixtures) by volume, the potassium mixture-water blend forms a soft ice blend at about minus 16° C. or 4° F.
In another example, the potassium mixture was diluted with about 50% by volume of tap water: The freeze point of the blend is less than minus 16° C. or 4° F. (potassium mixture-water blend did not freeze at about minus 16° C. or 4° F.). When the potassium mixtures was mixed with about 75% water by volume (about 25% potassium mixture by volume), the potassium mixture-water blend formed a slush, soft ice blend at about minus 16° C. or 4° F. In these examples the potassium mixtures comprised: 21% ash, 46% glycerol, 0.15% methanol, 0.05% moisture, 13% potassium, 7% fatty acids.
Per published data (Dow Company, www.dow.com) a straight 25% glycerol-water solution would have a freeze point of minus 7° C. or 19° F. In the above example the freeze point of the potassium mixture-water blend containing about 23% glycerol did not freeze at minus 16° C. or 4° F.
The unexpected formation of soft ice is very important in freeze conditioning applications. For example, if the potassium mixtures and water blend is sprayed onto coal it can prevent the coal from agglomerating in freezing weather, allowing the coal to be transferred, including unloading coal from railcars. Coal or solids can be transferred or transported, and not form a large frozen mass which makes transloading difficult if not impossible.
It is important to note ice may form in freeze conditioning applications of the potassium mixtures, but the ice crystals are soft preventing the icing together or agglomeration of particles including coal. The potassium and water blend can be applied similarly to any particular material that needs to be freeze condition during the winter or in cold weather.
Without being limited by theory, it is believed that freeze conditioning results from a weakening of the bonds between forming ice crystals which prevent agglomeration of the particulate material into a solid mass. Thus although water contained in the particulate material is frozen in a typical application, the particulate material does not freeze into a solid mass.
Freeze conditioning is therefore distinct from deicing or anti-icing. For purposes of this application, the definition of “deicing” is a process in which formed ice is converted to water by depressing the freezing point depression of the ice. For purposes of this application, the definition of “anti-icing” is a process in which an agent is applied to a surface or material to prevent formation of ice when the surface or material is contacted by precipitation. Most importantly, the dosage required for freeze conditioning is substantially lower than the dosage required for deicing or anti-icing. In at least one embodiment the potassium mixture composition is applied to particulate materials under conditions such that (so cold that) and in a dosage such that the composition is ineffective as a deicing agent or anti-icing agent but is effective as a freeze conditioning agent.
Different types of water can be use to blend with the potassium mixtures, including tap water, distilled water, deionized water, wastewater, runoffs, process water, or contaminated water including industrial flowback water and/or produced water, treated or untreated. pH adjustment and/or filtration maybe required. The produced water can be generated from mining, natural gas, fracking, geothermal energy, or drilling operations. Flowback water and produced water are described in U.S. Pat. No. 9,683,153, Davis, et al.
The potassium mixtures can be use in freeze conditioning and deicing/anti-icing applications. It can be mix or blend with other freeze point depressants or deicing/anti-icing materials including glycols, sugar-beets formulation, sugared/desugared formulas, and/or inorganic salts.
In an embodiment the potassium mixtures or dilution of the mixtures can be applied from about 1 to about 4 pints per ton of coal for freeze conditioning. Dosages less than 1 pint per ton of coal are possible due to the soft ice formation. Extreme cold weather may require a higher dosage.
In an embodiment, additives can be added to the potassium mixtures including corrosion inhibitors. In an embodiment the pH of the potassium mixtures ranges from 6-12. In an embodiment the pH of the potassium mixtures ranges from 10-12. High pH can mitigate corrosion. The mixtures can be diluted with water as mentioned above.
In embodiment the potassium mixtures can be applied to roads or structures to prevent icing in freezing weather. The stream can be diluted with water from about 10% to about 1,000% by weight or by volume in the applications referenced of the present invention. In freeze conditioning applications, it may be possible to dilute the potassium mixtures greater than 1,000% by volume or weight with water due to the soft ice formation.
Another unique, beneficial characteristic of the potassium mixture is it does not contain chloride. Production of FAAE and glycerol from other commercial processes generates streams including by-products that contain chloride, particularly sodium chloride. Existence of sodium chloride in by-product streams is noted in Tran's patents referenced above. The present invention having no chloride is beneficial with regards to the applications of this invention. Chloride damages vegetation and the environment, and is harmful to fish, pets, and wildlife. Chloride also causes corrosion to equipment, structures, bridges, and vehicles. Structures can include steel and concrete.
Another beneficial characteristic of the present invention is it lacks water or moisture. Typical moisture level of the potassium mixtures is about 0.06% by weight. These are concentrated mixtures that can be diluted in applications mentioned in the present inventions. By-products from production of FAAE and glycerol from other commercial processes typically comprise a large portion of water, for example, about 20-30% water or more. These products can be used directly in commercial applications. A distinguishing characteristic of the potassium mixtures is that it is very viscous and it freezes at typical water freeze temperatures, making the mixtures very difficult to use directly or apply as is. In an embodiment heat is provided or water is added to improve flow.
It is noted that commercially available compositions are prepared by mixing glycerol and potassium acetate (commercially made) together. The present invention offers an economical benefit by employing a waste residue that comprise both components. It is also noted that similar commercially available compositions suggest adding a corrosion inhibitor because of the chloride content in by-product glycerol. The present invention offers another benefit that it does not contain any chloride that can promote corrosion.
