Abstract
Prilled lime compositions and associated systems and methods are disclosed herein. In some embodiments, the prilled lime composition comprises 1-10% by weight of a binder; 45-75% by weight calcium hydroxide; no more than 30% magnesium oxide; and 1-10% water. The binder can include molasses, sodium lignosulfonate, calcium lignosulfonate, starch, sodium silicate, or bentonite.

A prilled lime composition, comprising:
- 1-10% by weight of a binder, wherein the binder comprises at least one of sodium lignosulfonate, calcium lignosulfonate, starch, molasses, sodium silicate, or bentonite;
- 45-75% by weight calcium hydroxide;
- no more than 30% magnesium oxide;
- and
- 1-10% water.
A prilled lime composition, comprising:
- at least 70% by weight calcium carbonate;
- 1-10% by weight of a binder;
- 1-8% by weight calcium hydroxide and/or magnesium oxide;
- and
- 1-6% water.
The composition of 12, wherein:
- the calcium carbonate comprises 75-90% by weight of the composition, the calcium hydroxide comprises 2-6% by weight of the composition, the water comprises 2-5% by weight of the composition.
A method for producing a prilled lime composition, comprising:
- combining lime and magnesium oxide to from a first mixture;
- combining the first mixture and a binder to form a second mixture, wherein the binder comprises at least one of sodium lignosulfonate, calcium lignosulfonate, starch, molasses, sodium silicate, or bentonite;
- combining the second mixture and additional lime to form a third mixture;
- and
- heating the third mixture to form a product composition.
