Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial water-containing systems face significant challenges due to scale accretion, which leads to reduced fluid flow, inefficient heat transfer, and increased risk of corrosion, resulting in operational delays and revenue losses.
Innovation Solution
The method involves adding an aqueous formulation containing polyammonium bisulfate (PABS) molecular clusters, sulfuric acid, and water to the water-containing system, with concentrations ranging from 0.01 ppm to 10,000 ppm, to inhibit scale accretion and remove existing scale deposits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional scale prevention products are used, then scale formation is reduced, but the safety for infrastructure (pipes, containers, membrane filters, pumps) deteriorates
Solution Approach 1:
The patent changes the chemical parameters of the scale prevention product by using polyammonium bisulfate molecular clusters instead of conventional scale inhibitors. This parameter change allows the product to effectively prevent scale formation while being safer for infrastructure, as the PABS clusters specifically target scale precursors without causing corrosion or damage to metal surfaces, membranes, and other infrastructure components.
2Productivity
If scale is allowed to form, then fluid flow is reduced, but heat transfer efficiency deteriorates
Solution Approach 1:
The patent applies preliminary action by adding polyammonium bisulfate molecular clusters to the water system before scale formation occurs. The PABS clusters prevent scale accretion at the nucleation stage by interacting with scale-forming ions and preventing their deposition on surfaces. This preliminary prevention maintains both fluid flow and heat transfer efficiency by avoiding the formation of insulating scale layers that would otherwise reduce thermal conductivity and restrict flow.
3Object-generated harmful factors
If scale removal methods are applied, then existing scale deposits are removed, but operational disruptions increase
Solution Approach 1:
The patent enables continuity of useful action by providing ongoing scale prevention through continuous addition of polyammonium bisulfate molecular clusters to the water system. Rather than requiring periodic shutdowns for scale removal, the PABS clusters continuously inhibit scale formation at the point of deposition. This continuous protection eliminates the need for operational disruptions to remove scale deposits, maintaining uninterrupted fluid flow and heat transfer operations.

AI summary
The present disclosure provides an improved scale inhibiting formulation that is effective, environmentally friendly, and does not add any organic compounds or traditional polymeric compounds to treated water. The scale inhibiting composition includes molecular clusters of polyammonium bisulfate (PABS), which can interact physically, chemically, or physio-chemically with one or more ions in the water or water-containing system being treated. That interaction inhibits scale accretion and/or removes previously formed scale.
