Recommendations for “Top Posts” in the Synthetic Ammonia section
Thread Content
Please ask the moderators to select a number of outstanding posts (topic posts) within the area dedicated to technical exchanges on ammonia synthesis processes (excluding the information section), with the following requirements:； 1. Posts related to technical exchanges are preferred (requests for help, discussion posts, sharing posts, etc. are all acceptable). 2. Organizational posts and survey posts are also okay, but there should not be too many of such posts. Up to 10 posts can be recommended by 3 people. (One’s own posts can also be recommended.) Regular members can participate in recommendations. Based on comprehensive recommendations, post quality, views, as well as the number and quality of replies, some excellent posts are marked as favorites!
1. Discuss the consumption of synthetic ammonia. 2. What measures can be taken to increase ammonia production? 3. What factors cause poisoning and degradation of ammonia synthesis catalysts? 4. How should the synthesis system be operated when the hydrogen-to-nitrogen ratio is out of balance? Last edited by snowdfr on 2009-2-13 13:15 in this post.]

Our factory’s decarburization system previously used pumps imported from the United States to inject defoamers into the system (plunger pumps); after several years of operation, problems arose frequently – the pumps would not function properly, and the defoamers could not be delivered. Later, a funnel-shaped container was directly installed at the outlet of the defoamer pump, with its larger end facing upward, and it was connected to the outlet pipeline of the defoamer pump to add the chemical to the system. Added to the inlet of the lean liquid pump; the low inlet pressure provides a suction effect. It works very well. Normally, a cover is placed on top of the funnel to prevent impurities from entering the system. The only drawback is that some personnel do not follow the regulations regarding the addition of chemicals – instead of mixing them with a certain amount of deionized water as required, they add pure defoamers directly, which can cause fluctuations in the absorption process in the absorber tower
