Application of ultrafiltration technology in ammonia synthesis

This post was last edited by ZZJJAA70 on 2009-10-15 13:05 What is the effect of ultrafiltration technology used in synthetic ammonia oil and other parts, and what are its advantages and disadvantages.
Ultrafiltration technology is used a lot in the production of synthetic ammonia, and the effects are also different. It is mainly effective under the conditions of high pressure and low temperature. When the pressure is low and the temperature is high, the efficiency is poor. For example, when the imported gas temperature is high, it cannot be separated. The pressure difference will be large in the later period of use, which will have a great impact on the system and is not easy to use.； In the ammonia synthesis system, the pressure is high, the pressure difference is not obvious, the temperature is low, and the use effect is good. Disadvantages: short service life.
In order to ensure the filtration effect, what is the general precision of this ultrafiltration filter element in microns?
Are there any experts in ultrafiltration in Xi'an? Can anyone tell me professionally about your introduction of foreign filter elements? Everyone wants to know.
Ultrafiltration technology has a very good effect in methanol separation. It can reduce the methanol content in the post-alcohol gas and the methanol brought into the alcohol washing tower, improve the quality of crude alcohol, reduce the amount of steam used in refined alcohol processing and production, and reduce costs.； Among the synthetic ammonia produced from nitrogen fertilizers, some are also very good for use in ammonia separators. Shandong Ningyang Fertilizer Factory is an early company that used it. I heard that it is used well, but I don’t know how long its service life is.
