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 1 and 5, and x may be between 1 and 10.
