Abstract
Liquid suspensions are disclosed that include superabsorbent polymer suspended within a non-aqueous liquid. The liquid suspensions are capable of being pumped and sprayed onto waste fluids for clean-up procedures. The liquid suspensions can be made by high shear mixing of the superabsorbent polymer with the non-aqueous liquid until the superabsorbent polymer is suspended within the non-aqueous liquid.
Claims37
A liquid suspension for use in cleaning waste fluids, the liquid suspension comprising:
- a non-polar liquid;
- and
- a plurality of particles comprising superabsorbent polymer, wherein the plurality of particles are suspended within the non-polar liquid.
(canceled)
A method of making a liquid suspension, the method comprising:
- providing a plurality of particles of superabsorbent polymer;
- providing a non-polar liquid;
- and
- mixing the plurality of particles of superabsorbent polymer with the non-polar liquid until at least a portion of the plurality of particles of superabsorbent polymer are suspended within the non-polar liquid, forming the liquid suspension.
(canceled)
24-34. (canceled)
A method of cleaning up a waste fluid at a site, the method comprising:
- providing a liquid suspension at the site, wherein the waste fluid is present at the site, and wherein the liquid suspension comprises a plurality of particles of superabsorbent polymer suspended within a non-polar liquid;
- applying the liquid suspension onto the waste fluid at the site;
- wherein, upon or after the application of the liquid suspension onto the waste fluid, the plurality of particles of superabsorbent polymer absorb at least a portion of the waste fluid;
- and
- retrieving the plurality of particles of superabsorbent polymer, with the waste fluid absorbed therein, from the site.
