Abstract: A solution including an associative polymer, a cyclodextrin polymer, and a solvent is provided. The associative polymer is a powder in the absence of the solvent. Additionally, a method of making down an associative polymer powder to form a solution is provided. The method includes blending a mixture of the powder, a cyclodextrin polymer, and a solvent to yield the solution, wherein the powder includes particles having been dry-cut to a median particle size of from about 200 microns to about 10,000 microns. Additionally, a powder product is provided. The powder product includes from about 80 wt. % to about 99.9 wt. % associative polymer; and from about 0.1 wt. % to about 20 wt. % of a cyclodextrin polymer.

Abstract: Additives including sulfur-containing compounds are used in methods of treating synthetic gypsum. The additives can thermally stabilize heavy metals, such as mercury. This thermal stabilization reduces mercury release from the synthetic gypsum. Illustrative, non-limiting examples of sulfur-containing compounds include inorganic sulfides, organic sulfides, organic compounds containing nitrogen and sulfur, organic compounds containing oxygen and sulfur, and polymers containing sulfur.

Abstract: Methods for facilitating the removal of mercury from flue gases by converting elemental mercury to oxidized mercury and subsequently capturing the oxidized mercury. In one aspect, a method of removing mercury from a mercury-containing flue gas may include the steps of introducing into the flue gas a sulfide source in an effective amount to convert elemental mercury to gaseous oxidized mercury and then capturing the gaseous oxidized mercury.
Abstract translation: 通过将元素汞转化为氧化汞并随后捕获氧化汞来促进从烟道气中去除汞的方法。 一方面，从含汞烟道气中去除汞的方法可包括以下步骤：将有效量的硫化物源引入烟道气中，以将元素汞转化为气态氧化汞，然后捕获气态氧化汞。
