  • Patent number: 10807889
    Abstract: A base product fluid is produced by adding anhydrous liquid ammonia and a first portion of sulfuric acid to water in a process line to form a mixed fluid. The mixed fluid may be cooled and a second portion of sulfuric acid may be added to the mixed fluid to form the base product fluid. The base product fluid may include a molecular compound that is a chelating compound. The molecular compound may have the formula: ((NH4)2SO4)a.(H2SO4)b.(H2O)c.(NH4HSO4)x. In the formula, a may be between 1 and 5, b may be between 1 and 5, c may be between 0 and 5, and x may be between 1 and 20.

  • Patent number: 10662093
    Abstract: An agriculture treatment solution may include one or more metal salts and a base product fluid. The base product fluid may include a molecular compound that is a chelating compound. The molecular compound may have the formula: ((NH4)2SO4)a.(H2SO4)b.(H2O)c.(NH4HSO4)x. In the formula, a may be between 1 and 5, b may be between 1 and 5, c may be between 1 and 5, and x may be between 1 and 10. The agriculture treatment solution may be formed by adding the one or more metal salts to the base product fluid and water. The agriculture treatment solution may be added to an agricultural crop to deliver at least one of the metal salts to the agricultural crop. The at least one metal salt may be a micronutrient for the agricultural crop.

  • Patent number: 10093563
    Abstract: A base product fluid is produced by adding anhydrous liquid ammonia and a first portion of sulfuric acid to water flowing in a process line to form a mixed fluid. The mixed fluid may be cooled by flowing the mixed fluid through a heat exchanger. A second portion of sulfuric acid may be added to the mixed fluid to form the base product fluid. The second portion of sulfuric acid may be greater, by weight, than the first portion of sulfuric acid. The base product fluid may include a molecular compound that is a chelating compound. The molecular compound may have the formula: ((NH4)2SO4)a.(H2SO4)b.(H2O)c.(NH4HSO4)x.
