Disposal of sulfur through use as sand-sulfur mortar

摘要

A sulfur-sand limestone mortar and methods of preparing the sulfur-sand limestone mortar and disposing of elemental sulfur, are disclosed. In embodiments, the sulfur-sand limestone mortar includes elemental sulfur, limestone powder, and sand. Modifiers, such as plasticizers, are not required and are not used in embodiments of the sulfur-sand limestone mortar. In embodiments of the method to prepare the sulfur-sand limestone mortar, each of the elemental sulfur, limestone powder, and sand are heated to at least 140 C, then combined, and then allowed to solidify.

主权项

1. A method for disposing of elemental sulfur comprising the steps of:
heating elemental sulfur to a liquid state, where the temperature of the liquid-state elemental sulfur is in a range of from about 127° C. to about 149° C.; heating each of limestone powder and sand to at least 140° C. but no greater than about 149° C.; combining the liquid-state elemental sulfur with each of the heated limestone powder and sand such that the temperature does not exceed about 149° C. to define a mortar mixture; and solidifying the mortar mixture through cooling, where the composition has an absence of fine entrained gas cells, and where the composition has an absence of modifiers.
