Issues regarding the potassium-alkali decarbonization system for synthetic ammonia phenylphthalein process

Thread Content

I’m a beginner and have only been working with synthetic ammonia for a short time. However, from the Internet as well as from my classmates and colleagues, I’ve learned that there are quite a number of synthetic ammonia systems that use phenol-thermal potassium-alkali decarburization, but many of these systems encounter problems. Small impacts cause slight fluctuations in the system, while larger impacts require stopping the operation to replace the solution. . . . . . Decarbonization has become the bottleneck determining the quality of the entire system! ! ! ! I searched on the forum, but couldn’t find any discussions about it, so I’m raising the question again. I hope experts can give me some guidance. How to solve it and stabilize the system? ? ? ? ? ? For example: The system solution tends to form foam easily, and a large amount of defoamer is required – how can this be improved? (Does using too much defoamer have a significant impact on the system?) ； With the use of system activators, do ordinary activators change within the system, forming other substances that could affect the system? ； Experience in the control and removal of chloride ions and iron ions in the system. . System thermal load control: what level is appropriate? What are the hazards if it’s too high or too low? There are so many questions; I can’t list them all. I hope those who are more experienced will share their knowledge~~~~~~~
