Abstract
Systems and methods for forming aqueous based, water-soluble polymer slurry systems may include (1) a liquid phase which may be a suspension comprised of salt, water, and a water-soluble organic solvent and (2) a solid phase which may comprise a water-soluble polymer powder. The aqueous based, water-soluble polymer slurry systems may optimize processing of the suspension package so that it may slurry in low and high salt tolerance polymers, and the finished product can survive over 30 days at an approximately 120-degree Fahrenheit aging temperature, thereby overcoming economic performance and stability challenges through its high flash point, long shelf-life, high-temperature tolerance, and low cost.
Claims20
An aqueous based, water-soluble polymer slurry system comprising:
- a liquid phase comprising water, one or more inorganic salts, and one or more water-soluble organic solvents;
- a solid phase comprising a water-soluble polymer powder or polymer mixer, wherein the amount of the one or more inorganic salts in the liquid phase is greater than the one or more inorganic salt's solubility in water;
- and
- wherein the liquid phase comprises about 45-90% by weight of the polymer slurry system.
A method to form an aqueous based, water-soluble polymer slurry system comprising:
- dissolving one or more inorganic salts in water to form a salt solution at an elevated temperature that increases the solubility of the one or more inorganic salts;
- mixing one or more water-soluble organic solvents into the salt solution at the elevated temperature until the one or more water-soluble organic solvents is fully dissolved into the salt solution;
- cooling the salt solution to a second temperature wherein a portion of the one or more inorganic salts are suspended in the salt solution;
- and
- adding a water-soluble polymer or polymer mixer to the suspension to form a slurry;
- and
- wherein the polymer slurry system survives over 30 days at an approximately 120-degree Fahrenheit aging temperature.
An aqueous based, water-soluble polymer slurry system comprising:
- a liquid phase comprising water, one or more inorganic salts, and one or more water-soluble organic solvents;
- a solid phase comprising a water-soluble polymer powder or polymer mixer,
- wherein the amount of the one or more inorganic salts in the liquid phase is greater than the one or more inorganic salt's solubility in water;
- and
- wherein the slurry system comprises about 10-53% water by weight, about 10-44.5% of one or more inorganic salts by weight, and about 1-85% of one or more water-soluble organic solvents by weight.
