Abstract

The invention provides methods and compositions for freeze conditioning particulating materials. The invention includes the use of the combination of crude glycerin with flowback or produced water. This combination prevents unwanted agglomeration when frozen. This combination also is non-corrosive and best of all facilitates the safe clean recycling of what would otherwise be unwanted dangerous waste material.

First claim

The invention claimed is:

1. A method of inhibiting the agglomeration of a particulate material exposed to below freezing temperature, the method comprising the step of applying to the particulate material a fluid comprising flow back water and/or produced water, and crude glycerin.

2. The method of claim 1 wherein the crude glycerin comprises bottom stream.

3. The method of claim 1 wherein the fluid is essentially flow back water.

4. The method of claim 1 wherein the fluid is essentially produced water.

5. The method of claim 1 wherein the fluid and crude glycerin are pre-mixed before contacting the particulate material.

6. The method of claim 1 wherein the fluid and crude glycerin do not contact each other until after they are applied to the particulate material.

7. The method of claim 1 in which the dosage of crude glycerin in the presence of the below freezing temperature would be insufficient to prevent the agglomeration of the particulate material but for the presence of the fluid.

8. The method of claim 1 , wherein the fluid comprises at least one item selected from the group consisting of: hydrochloric acid, acetic acid, formic acid, 2,2-dibromo-3-nitrilopropionamide, polycyclic organic matter, polynuclear aromatic hydrocarbons, glutaraldehyde, diammonium peroxidisulfate, ammonium persulfate, ammonium sulfate, ethylene glycol, glycol ethers, tetramethyl ammonium chloride, potassium chloride, methanol, propargyl alcohol, boric acid, monoethanolamine, polyacrylamide, sodium acrylate-acrylamide copolymer, guar gum, citric acid, thioglycolic acid, diesel, benzene, toluene, ethylbenzene, xylene, naphthalene, sand, ceramic beads, ammonium chloride, polyacrylate, methanol, isopropanol, peracid, biocide, breaker, clay stabilizer, corrosion inhibitor, crosslinker, friction reducer, gelling agent, iron control agent, linear gel carrier fluid, proppant, scale inhibitor, surfactant, and any combination thereof.

9. The method of claim 1 , wherein the fluid comprises at least one item selected from the group consisting of: chloride, strontium, barium, boron, chromium, selenium, lead, arsenic, radium-226, heavy metals, methane, alkali metals, alkaline earth metals, anionic ions, cationic ions, dispersed rock, and any combination thereof.

10. The method of claim 1 wherein the fluid and crude glycerin is distributed throughout a pile of particulate material.

11. The method of claim 1 in which the ratio of fluid relative to crude glycerin is within range of from 1:99 to 99:1.

12. The method of claim 1 in which either or both of the fluid and the crude glycerin comprise at least one salt in an amount sufficient to induce corrosion on an iron comprising object in contact with the particulate material but the salt will not induce such corrosion.

13. A method of inhibiting the agglomeration of a particulate material exposed to below freezing temperature, the method comprising the step of applying to the particulate material a fluid comprising flow back water and/or produced water, and crude glycerin.
