Homogeneous membrane electrodialysis device: a new breakthrough in desalination of betaine industry

Author：

In the process of betaine synthesis, sodium chloride is inevitably produced as a by-product. All along, the original process mainly uses evaporation concentrated salt or heterogeneous membrane electrodialysis salt removal these two ways. However, in practical applications, evaporation and concentration salt analysis method has many drawbacks, it not only needs to consume a lot of energy, resulting in high operating costs, and desalting effect is not ideal, desalting rate is low, making the quality of the final product difficult to reach a high standard. Heterogeneous membrane electrodialysis salt removal is also facing similar problems, although it can be achieved to a certain extent, but the high operating cost and low desalination rate still limit its further development in betaine synthesis process.


With the continuous progress of science and technology, a more advanced technology - homogeneous membrane electrodialysis device came into being, and gradually in the betaine industry has been widely used. The homogeneous membrane electrodialysis device has significant advantages, and its operating cost is much lower than that of the traditional evaporation desalt and heterogeneous membrane electrodialysis methods, which can save a lot of costs for enterprises. At the same time, the desalting rate is quite high, which can remove the by-product sodium chloride more effectively, thus significantly improving the quality of the product. Because of these outstanding advantages, at present, the utilization rate of the homogeneous membrane electrodialysis device in the betaine industry has reached more than 70%, and has become an important technical support for the desalination link in the betaine synthesis process, which has brought new opportunities and vitality for the development of the betaine industry.

The low concentration of sodium bromide wastewater from the production of flame retardants is concentrated to more than 15% by the homogeneous membrane electrodialysis unit, and then it is recycled into the evaporation unit. The salt content of the produced fresh water is reduced to 0.1% and can be recycled. The process reduces the cost and realizes the recycling of waste resources.
