Abstract:
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.
Abstract:
The present disclosure is generally directed to a water processing system. In some embodiments, the water processing system may be configured to generate a potassium salt, such as potassium nitrate, an ammonium salt, such as ammonium nitrate, or both. In some embodiments, the water processing system may be at least partially powered by renewable energy, such as by using a liquid storage system that is at least partially underground. In some embodiments, the water processing system may be configured to reuse certain greenhouse emissions to improve performance of power generation systems associated with the water processing system.
Abstract:
A method for production of ammonium phosphate from phosphate rock slurry. The method includes: introducing flue gas containing SO2 into a phosphate rock slurry, to yield an absorption solution; evaporating waste ammonia water containing 10-20 wt. % ammonia to yield ammonia gas; introducing the ammonia gas into the absorption solution at a temperature of 110-135° C. until a neutralization degree of the absorption solution reaches 1.5-1.6, thus yielding an ammonium phosphate solution and calcium sulfate; separating the calcium sulfate from the ammonium phosphate solution; and introducing the ammonium phosphate solution to a granulator for granulation to yield ammonium phosphate granules; drying and sieving the ammonium phosphate granules, thereby yielding ammonium phosphate.
Abstract:
Disclosed herein are compositions comprising a super absorbent polymer (SAP) concentrate mixed with a long-term fire-retardant concentrate, prior to dilution with water, to form a mixed concentrate and methods of making such compositions. The mixed concentrate composition can be subsequently mixed with water to produce an aqueous fire-fighting solution.
Abstract:
Flame retardant covers for mattress and flame retardant mattresses are provided. At least a portion of the fibers, yarns or the fabric of the covers is treated with a blend comprising a flame retardant compound such as ammonium phosphate. The covers do not further require any flame barrier element such as fiberglass or silica-loaded rayon. The mattresses provided herein fully comply with the federal mattress flammability standards of 16 C.F.R. 1632 and 1633.
Abstract:
A method for concentration of phosphate compounds comprises dissolving (205) of sludge ash in hydrochloric acid. Insoluble residues are separated (210), thereby forming a first leach solution. A mole ratio of phosphorus to a sum of ferric iron and aluminum in the first leach solution is controlled (215) to be larger than 1. A base is added (220) to the first leach solution in an amount causing precipitation of phosphate compounds. The precipitated phosphate compounds are removed (225) from the first leach solution. Sulphuric acid is added (240) to the first leach solution, causing precipitation of sulphate compounds. The precipitated sulphate compounds are separated (245) from the first leach solution. At least a part of the leach solution is recycled (248) as the hydrochloric acid used for the dissolving of sludge ash. Further methods for processing the precipitated phosphate compounds are presented as well as arrangements for performing the methods.
Abstract:
Novel smoldering suppressing compositions containing a metal complex of ammonium superphosphoric acid and having a high phosphate content, and processes for their preparation, are disclosed. Further disclosed are formulations containing these compositions and articles-of-manufacture having these formulations applied thereon. These novel formulations are particularly effective as smoldering suppressants for textiles, and are characterized by a high washing fastness.
Abstract:
A flame retardant agent for a thermoplastic resin, which enables the thermoplastic resin containing the flame retardant agent to keep its viscous property, to be made into a fiber readily, and to exhibit flame retardant effect even when ammonium dihydrogen phosphate is contained in the flame retardant agent as a non-halogen flame retardant component. Also disclosed is a flame retardant resin composition containing the flame retardant agent. Specifically, the flame retardant agent for a thermoplastic resin comprises ammonium dihydrogen phosphate, potassium hydroxide, glycerin and urea, wherein the potassium hydroxide is contained in an amount of 10 to 70 parts by weight, glycerin is contained in an amount of 0.1 to 4.0 parts by weight, and urea is contained in an amount of 1 to 9 parts by weight relative to 100 parts by weight of ammonium dihydrogen phosphate.
Abstract:
Systems and methods of producing chemical compounds are disclosed. An example chemical production system includes a combustion chamber having intake ports for entry of a gas mixture. An igniter ignites the gas mixture in the intake chamber to facilitate a reaction at a high temperature and high pressure. A nozzle restricts exit of the ignited gas mixture from the combustion chamber. An expansion chamber cools the ignited gas. The expansion chamber has an exhaust where the cooled gas exits the expansion chamber. A chemical compound product is formed in the expansion chamber.
Abstract:
The present invention generally relates to a process for preparing stabilized polymeric systems with excellent light, thermal and oxidation stability using an active, peroxide containing polymer oxidizing agents, amine-containing reducing agents, and/or nano-additives, and the polymer articles made therefrom.
