Electrodialysis process: sodium formate pentaerythritol material separation, open a new chapter of efficient and clean production
Author：
As an advanced membrane separation technology, electrodialysis has shown remarkable advantages in many industrial processes. Compared with the traditional process, its outstanding characteristics are reflected in the simplification of the process flow and the optimization of various production indicators.
2. Specific advantage analysis
1. Simplify the process
The traditional process often involves a series of complicated steps such as rectification, evaporation, crystallization and desalting, but the electrodialysis membrane process is very simple. Through its unique membrane separation principle, it can directly separate materials efficiently, skillfully avoiding those lengthy and energy-consuming traditional processing links. This not only greatly shortens the entire production cycle, improves production efficiency, but also reduces various process failures and product quality instability factors that may be caused by complex steps.
2. Improve the removal rate of sodium formate byproduct
In the production process, the effective treatment of sodium formate by-products is very important for product quality and economic benefits. The electrodialysis process is excellent in this respect, and the separated sodium formate byproducts are completely free of pentaerythritol. This feature greatly reduces the loss rate of pentaerythritol products that often occur in traditional processes. In the past, due to the inaccurate separation of the traditional process, part of pentaerythritol will be lost along with sodium formate by-products, resulting in product waste and economic benefit reduction. The electrodialysis process, with its high-precision membrane separation performance, realizes the precise separation of sodium formate and pentaerythritol, ensuring the high yield of pentaerythritol products.
3. Energy saving and product quality assurance
Saving evaporation energy: The evaporation step in the traditional process usually consumes a lot of energy, while the electrodialysis process does not need to carry out this energy-intensive operation. Through the selective transmission of the membrane, the separation of the target substance is directly realized, thus avoiding the huge energy consumption caused by the evaporation process, and effectively reducing the production cost.
Reduce process water: The electrodialysis process also eliminates the washing step, which undoubtedly greatly reduces the demand for process water compared to the traditional process. At a time when water resources are increasingly stressed, this not only helps enterprises reduce water costs, but also reflects good environmental benefits. Ensure product content: More importantly, the content of sodium formate by-products and pentaerythritol separated by electrodialysis can reach a higher level of more than 15%. This means that while achieving efficient separation, it can also ensure that the resulting product has a high purity and concentration, further enhancing the market competitiveness of the product.
4. Operation and cost advantage
Easy operation: The operation of electrodialysis process is relatively simple and convenient. It is based on the mature and stable technical principle, and the operator can master the relevant operation process after appropriate training. There is no need for complex process control and cumbersome equipment maintenance, which greatly reduces the difficulty and workload of manual operation.
Less investment: In terms of equipment investment, electrodialysis process compared with the traditional process required by large distillation, evaporation, crystallization and other equipment, its equipment composition is relatively simple, occupies a small area, the initial investment cost is significantly reduced. For enterprises, especially small and medium-sized enterprises, this reduces the threshold to enter the relevant production fields and helps to promote the development of the industry.
Automatic clean production can be realized: The electrodialysis process can be well combined with the automatic control system to realize the fully automated operation of the production process. From material feeding and membrane separation processes to product discharge, the entire process can be operated efficiently and stably under the precise control of automated programs. Moreover, because it avoids a large amount of waste water, waste residue and other pollutants that may be produced in some traditional processes, it achieves a relatively clean production process, which meets the requirements of modern industry for environmental protection and sustainable development.
To sum up, the electrodialysis process with its many advantages in the related industrial production field has shown a broad application prospect, has brought significant economic and social benefits for enterprises.
