Abstract

The present disclosure relates to a defoaming substance for defoaming an aqueous solution. The defoaming substance includes a defoaming agent and a carrier material intermixed with the defoaming agent to form a solid mass, the carrier material being at least minimally soluble in the aqueous solution. In one embodiment, the carrier material includes at least one type of organic acid. The defoaming agent may include at least one type of silicon-based defoamer. The present disclosure also relates to a method for making a defoaming substance. The method may include selecting a defoaming agent capable of hindering foam formation and reducing foam build-up in an aqueous solution, selecting a carrier material that is at least minimally soluble in the aqueous solution, combining the defoaming agent with the carrier material, and forming the combined defoaming agent and carrier material into a solid defoaming substance.

Claims (17)

1. A defoaming substance for defoaming an aqueous solution, consisting of:

a defoaming agent; and

a carrier material intermixed with the defoaming agent to form a solid mass, the carrier material consisting of at least one organic acid;

wherein the mass ratio of the defoaming agent to the carrier material is in the range of between about 1:5 and 1:20.

2. The defoaming substance of claim 1 , wherein the carrier material consists of at least two different organic acids, wherein each organic acid has a different water solubility.

3. The defoaming substance of claim 1 , wherein the defoaming agent comprises at least one type of silicon-based defoamer.

4. The defoaming substance of claim 1 , wherein the carrier material has a melting point in the range of between about 50 degrees Celsius and 200 degrees Celsius.

5. The defoaming substance of claim 1 , wherein the carrier material has a melting point of about 100 degrees Celsius.

6. The defoaming substance of claim 1 , wherein the mass ratio of the defoaming agent to the carrier material is about 1:10.

7. A method for making a defoaming substance, consisting of:

selecting a defoaming agent capable of hindering foam formation and reducing foam build-up in an aqueous solution;

selecting a carrier material, wherein selecting the carrier material consists of selecting at least two different organic acids, wherein each organic acid has a different water solubility;

combining the defoaming agent with the carrier material, wherein the mass ratio of the defoaming agent to the carrier material is in the range of between about 1:5 and 1:20; and

forming the combined defoaming agent and carrier material into a solid defoaming substance.

8. The method of claim 7 , wherein combining the defoaming agent with the carrier material comprises melting the carrier material and intermixing the defoaming agent and the carrier material.

9. The method of claim 8 , wherein forming the defoaming agent and carrier material into a solid defoaming substance comprises placing the intermixed defoaming agent and the carrier material into a mold and allowing time to cool.

10. The method of claim 7 , wherein combining the defoaming agent with the carrier material comprises compression fusing the defoaming agent together with the carrier material.
