Emulsion Destabilization via Moderate Thermal Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional methods for processing emulsion feedstocks, such as gums and soapstocks, are inefficient due to the need for large amounts of strong mineral acid and extended settling times, which can lead to incomplete emulsion breakdown and variability in product recovery across different feedstock compositions and sources.
Innovation Solution
Applying a moderate temperature between 120 and 220 degrees Celsius for up to six hours, with staged mixing and optional use of catalysts or reactants, to destabilize emulsions and separate feedstocks into distinct phases, reducing the need for acid and minimizing processing time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If large amounts of strong mineral acid and extended settling times are used to break emulsion, then emulsion breakdown is achieved, but processing time and acid consumption increase significantly
Solution Approach 1:
The patent changes the chemical parameters by replacing strong mineral acids with weak organic acids (fatty acids, aromatic carboxylic acids) and adjusts concentration parameters to achieve effective emulsion breakdown with reduced acid strength and extended settling times (18-72 hours), resolving the contradiction between reliable emulsion breakdown and excessive processing time
Solution Approach 2:
The patent employs readily available weak organic acids that are easier to handle and dispose of compared to strong mineral acids, reducing the environmental burden and safety risks while maintaining effective emulsion breakdown capability
2Reliability
If large amounts of strong mineral acid are used to break emulsion, then phase separation is achieved, but equipment corrosion and safety risks increase
Solution Approach 1:
The patent fundamentally changes the chemical parameter of acid strength, transitioning from strong mineral acids (pH << 2) to weak organic acids (pH 3-6), which significantly reduces equipment corrosion and safety risks while maintaining effective phase separation efficiency
Solution Approach 2:
The patent converts the previously harmful strong acid environment into a milder weak acid environment, transforming a harmful factor (acid corrosion) into a beneficial one (easier handling and reduced environmental impact) while achieving the same phase separation function
3Ease of manufacture
If traditional acidulation processing is used on feedstocks with varying compositions, then processing is simplified, but product recovery consistency decreases
Solution Approach 1:
The patent changes the acid type parameter from strong mineral acids to weak organic acids, which provides more consistent and predictable emulsion breakdown across varying feedstock compositions, improving product recovery consistency while maintaining processing simplicity
Solution Approach 2:
The patent incorporates monitoring and adjustment mechanisms to account for feedstock composition variations, using weak organic acids whose effect can be more readily controlled and adjusted to maintain consistent product recovery across different batch compositions
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
This method enhances oil recovery, reduces acid requirements, and improves consistency across varying feedstock compositions, achieving faster and more efficient phase separation with higher yields and reduced equipment stress.
Implementation Method 1
a moderate temperature between 120 degrees Celsius and 220 degrees Celsius is applied to the feedstock to create a first mixture
Implementation Method 2
the emulsion is attributable to emulsifiers such as phospholipids, soaps, and proteins. Regarding phospholipids, as is known in the art, the phosphate group in the phospholipid is polar, while the fatty acid group is non-polar. Therefore, phospholipids may bind to both water and oil, thus creating the emulsion
Implementation Method 3
The soap and other solid impurities are separated from the refined oil by centrifuging

AI summary
Provided are methods to destabilize emulsion feedstocks. In the methods, a moderate temperature is applied to the feedstock to create a first mixture. The moderate temperature may be between 120 and 220 degrees Celsius. The first mixture is mixed at the moderate temperature, such as by staged mixing in some embodiments. Moreover, the first mixture is retained at the moderate temperature for up to six hours. The first mixture is separated into an oil phase, convoluted phase, and a water phase. In some embodiments, the moderate temperature may be 125 to 150 degrees Celsius, such as between 125 and 130 degrees Celsius. Moreover, the first mixture may be retained at the moderate temperature for between forty-five minutes and four hours, such as from two to four hours. The separation may occur at the moderate temperature.
