Calcium Hydrate Oil Spill Binding Process
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for mitigating environmental pollution from oil spills, wastewater treatment, and fertilizer/pesticide runoff are inadequate, as they fail to effectively contain and remove pollutants from water surfaces and soil, often causing further environmental harm and financial losses.
Innovation Solution
A process involving the calcination of skeletal materials to produce calcium hydrate, which is then hydrated and applied to contaminated areas to bind pollutants, separating them from water and reducing their environmental impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If mechanical devices such as fences, booms, and skimmers are used to physically contain or remove oil, then oil removal from water surface is improved, but the ability to prevent emulsion formation and shoreline contamination is insufficient
Solution Approach 1:
The patent applies preliminary action by deploying the calcium hydrate composition onto the oil spill before it can emulsify or reach shorelines. The composition is applied proactively to prevent harmful transformations rather than reacting to them after occurrence. This is evident in the method where the composition is spread on the water surface to bind with oil before emulsion formation occurs.
Solution Approach 2:
The calcium hydrate composition serves as an intermediary substance between the oil and water, facilitating the binding and separation of oil from water. The composition acts as a mediator that chemically interacts with both substances, forming a bound complex that can be easily removed. This intermediary role is central to the invention's mechanism of action.
2Object-affected harmful factors
If chemical treatments such as drying oils, solvents, and catalysts are used to confine or coagulate spilled oil, then oil containment is improved, but environmental acceptability and effectiveness against emulsified oil deteriorate
Solution Approach 1:
The patent employs a disposable, environmentally benign calcium hydrate composition that performs its function and then can be safely discarded or left to degrade in the environment. The composition is designed to be non-toxic and environmentally acceptable, unlike persistent chemical treatments. It serves its purpose of binding oil and then can be removed or allowed to break down without long-term environmental harm.
Solution Approach 2:
The invention converts the typically harmful interaction between oil and water that leads to emulsion formation into a beneficial binding process. By introducing calcium hydrate, the harmful emulsification is transformed into a controlled binding reaction that produces a removable complex. The potential harm of chemical treatment is converted into benefit by using a naturally occurring, non-toxic substance.
3Stability of the object's composition
If high molecular weight polymers are used to gel or coagulate spilled oil, then oil coagulation is improved, but the ability to remove coagulated oil and prevent emulsion formation deteriorates
Solution Approach 1:
The patent changes the physical and chemical parameters of the oil through binding with calcium hydrate, transforming it from a free-floating or emulsified state to a bound, coagulated state that can be easily removed. The binding process alters the density, viscosity, and separability parameters of the oil, making it easier to remove from water. This parameter transformation is key to resolving the contradiction between coagulation effectiveness and ease of removal.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The calcium hydrate effectively removes oil from water surfaces, treats wastewater, and reduces fertilizer/pesticide runoff, leaving behind clear water and reducing soil and groundwater contamination, with no additional environmental hazards.
Implementation Method 1
the calcium hydrate product is added to a body of water contaminated with oil... the product binds with the oil, causing the oil to separate from the water
Implementation Method 2
heating marine shell material to about 2100 to 2350° F. (1150 to 1290° C.)... converts calcium carbonate in the shell to calcium oxide
Implementation Method 3
mixing water with the cooled shell material... as it cools is converted into a dry, substantially white, powdery material that is substantially of the consistency of talcum powder
