SUSTAINABLE PLASMA NITROPHOSPHATE PROCESS FOR PRODUCTION OF NITROGEN AND PHOSPHOROUS PRODUCTS AND FOR CARBON SEQUESTRATION
Provided herein are systems and methods for producing nitrophosphates and mineralized carbon. Advantageously, the systems and methods are capable of sequestering carbon from the atmosphere. The systems generally include a first reactor for producing nitric acid; a mixer for mixing the nitric acid produced in the first reactor with a phosphate source, thereby producing nitro-phosphoric acid; and a second reactor for producing a solution comprising nitrophosphates and mineralized carbon, wherein the second reactor is operable to receive: the nitro-phosphoric acid from the mixer, ammonia, water, and carbon dioxide.
Systems and methods for ammonia recovery, acid gas separation, or combination thereof
The present invention relates to processes and systems for ammonia recovery and/or acid-gas separation. In some embodiments, a system for acid gas separation may be integrated with an ammonia abatement cycle employing a high temperature absorber. In some embodiments, a system for acid gas separation may employ a higher temperature absorber due to the lower energy consumption and cost of the integrated ammonia abatement cycle. Advantageously, heat may be recovered from the absorber to power at least a portion of any acid gas desorption in the process. Reverse osmosis or other membranes may be employed.
Treatment of subterranean formations
A method of treating a subterranean formation by contacting the formation with the following: (a) ammonium compound; (b) an oxidizing agent selected from a perchlorate or a nitrite or combinations thereof; and (c) sulfamic acid.

PROCESS TO RECOVER AMMONIUM BICARBONATE FROM WASTEWATER
The present invention is a process, a method, and system for recovery and concentration of dissolved ammonium bicarbonate from a wastewater containing ammonia (NH3) using gas separation, condensation, filtration, and crystallization, each at controlled operating temperatures. The present invention includes 1) removal of ammonia from waste (sludges, semi-solids, and solids and liquids) without the use of chemicals at a temperature of at least 80 degrees Celsius, 2) mixing of the gaseous ammonia with carbon dioxide and water vapor and concentrating dissolved ammonium carbonate and ammonium bicarbonate using reverse osmosis at a temperature of between about 35 and 50 degrees Celsius, and 3) crystallizing concentrated dissolved ammonium carbonate and ammonium bicarbonate at a temperature of less than about 35 degrees Celsius to form solid ammonium bicarbonate and ammonium carbonate.

Method for Binding Hazardous Agricultural Ammonia Using Organic Carbon Dioxide
A method for binding hazardous agricultural ammonia using organic carbon dioxide reduces ammonia emissions from farming operations producing livestock, such as cows, pigs, and poultry. The method entraps a quantity of agricultural ammonia within an ammonia solution by reacting the quantity of agricultural ammonia with a quantity of organic carbon dioxide within a primary reaction vessel. The quantity of agricultural ammonia is mixed with a quantity of organic carbon dioxide to form an ammonia-bound solution. The ammonia-bound solution is able to be stored or transported for use in future chemical processes.

Process for desorption of ammonia chemical species using carbon dioxide, ammonia chemical species-providing agent, and apparatus for adsorption and desorption of ammonia chemical species
An ammonia chemical species desorption process desorbs ammonia chemical species adsorbed onto a Prussian blue derivative more simply at lower cost under milder conditions as compared with using an aqueous solution of a salt or strong acid, and only water. This ammonia chemical species desorption process includes an ammonia chemical desorption step of bringing carbon dioxide and water into contact with a Prussian blue derivative represented by the following general formula (1), thereby desorbing an ammonia chemical species.
