Advantages of N-methyldiethanolamine as a desulfurizer
1. Good security. Pipeline reaction can avoid the occurrence of detonation caused by local overheating, and it is a safe process route for ethylene oxide.
2. Good quality and few by-products. Controlling the ratio of cycloethylamine/methylamine can prevent the production of high boiling substances. The color of the product is very good, almost colorless. It has been proved by industrialization that the color of the product is much better than that of kettle reactor as well.
3. Very low energy consumption. Anhydrous monomethylamine can be used in the tubular reaction, and 40% aqueous methylamine solution is used in the kettle-type process. The latter consumes a lot of energy for distilling water, and the water content of the product is relatively high.
4. High output. Continuous reaction process, easy to start and stop, adjustable output per hour.
This process has been tested on an industrial scale of 600 tons per year, and has fully reached the international standard. Research and development personnel have successfully developed a domestic 10,000-ton-level ethanolamine production process, and reached the national level, and accumulated rich experience, providing a strong guarantee for the production process of MDEA.
