Transesterification System Reuses By-Product Fatty Acid Esters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high cost of producing high-purity triglyceride fats, such as USU and SUS, due to the requirement for large amounts of expensive fatty acid esters in enzyme interesterification reactions, leads to inefficient and costly production processes, with by-product fatty acid esters often being discarded or used for low-value applications.
Innovation Solution
A combined reaction system where by-product fatty acid esters from one reaction system are reused as raw materials in another, allowing for the efficient production of high-purity triglyceride fats by separating and recycling fractions of fatty acid esters through distillation and interesterification processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If enzyme interesterification is used to produce high-purity triglyceride fats, then the purity of specific triglyceride molecular species is improved, but the production cost increases due to requiring large amounts of expensive fatty acid esters
Solution Approach 1:
The invention recovers and reuses fatty acid esters that would otherwise be discarded as by-products from interesterification reactions. The process separates fatty acid esters from reaction products, purifies them through distillation, and reuses them as raw materials in subsequent reactions, thereby reducing the need for expensive fresh fatty acid esters while maintaining high triglyceride purity
Solution Approach 2:
The invention changes the physical state and purity parameters of fatty acid esters through controlled distillation processes. By adjusting distillation conditions (temperature, pressure, vaporization rate), the system transforms crude fatty acid ester by-products into high-purity raw materials suitable for reuse, optimizing both cost and quality
2Device complexity
If by-product fatty acid esters are discarded or used for low-value applications, then the production process is simplified, but resource utilization efficiency deteriorates and production cost increases
Solution Approach 1:
The invention establishes a continuous cycle where fatty acid esters are continuously recovered, purified, and reused in interesterification reactions. This closed-loop system eliminates waste by ensuring that fatty acid esters remain in continuous productive use rather than being discarded, thereby improving resource utilization without significantly increasing process complexity
Solution Approach 2:
The system serves itself by using its own by-products (fatty acid esters) as raw materials for continued production. The recovered fatty acid esters from reaction products are fed back into the reaction system, creating a self-sustaining process that reduces external material inputs and improves overall efficiency

AI summary
The present invention addresses the problem of providing a method for effectively producing a target oil/fat that is rich in triglyceride, by using liberated by-products such as fatty acid ester originating from starting material oil/fat that is separated from the target oil/fat efficiently after the reaction when producing the target oil/fat that is rich in triglyceride by a transesterification reaction using, for example, oil/fat and fatty acid ester as starting materials.
