Existing solubility enhancing compositions often form solids, such as salt crystals, which can cause deposition problems and equipment wear in industrial applications.
Innovation Solution
A solubility enhancing aqueous composition comprising a first solution with a concentration of sulfate ions from about 8.00 to 13.00 moles per liter and ammonium ions from about 1.45 to 2.01 moles per liter, combined with water to form a second solution that is substantially free of solids.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional solubility enhancing compositions are used, then solubility enhancement is achieved, but solids form causing deposition problems and equipment wear
Solution Approach 1:
The patent changes the chemical parameters by using specific concentrations of ammonium sulfate (1.45-2.01 moles per liter) and sulfuric acid (8.00-13.00 moles per liter) to maintain solubility enhancement while preventing solid formation. This parameter optimization resolves the contradiction by adjusting concentration levels to avoid saturation and precipitation.
Solution Approach 2:
The patent creates a composite aqueous composition containing multiple components (ammonium sulfate, sulfuric acid, and water) in specific proportions. This composite formulation achieves solubility enhancement while preventing solid formation through the synergistic interaction of components, resolving the contradiction between effectiveness and harmful solid generation.
2Quantity of substance
If chelating agents with solids are used, then metal ion carrying capacity is improved, but deposition problems and equipment wear occur
Solution Approach 1:
The patent modifies the physical state parameter by formulating a substantially solid-free liquid composition. By maintaining ammonium sulfate at 1.45-2.01 moles per liter and sulfuric acid at 8.00-13.00 moles per liter, the composition remains in liquid phase, eliminating deposition issues and equipment wear associated with solid chelating agents while retaining metal ion carrying capacity.
Solution Approach 2:
The patent transitions from solid-based chelating agents to a liquid/hydraulic-based composition. The aqueous solution format allows for fluid flow and distribution without the mechanical issues of solids, resolving the contradiction between metal ion carrying capacity and operational ease by eliminating particulate matter.
