Packed tray variable stripping column
Thread Content
Among those of us who work in synthetic ammonia production, many are aware that packed trays are not used in the stripping towers. Could someone explain how this modification is carried out and what the results are?
I can provide it to you: the performance is excellent, with low resistance and high efficiency. Wuhan Lide Fluid Technology Co., Ltd
A vertical sieve plate tower, right? With increasing production load and rising levels of imported hydrogen sulfide, considering replacing the original packed tower with a plate tower is an option. This is because the required gas velocity for a plate tower is higher than that for a packed tower. The pressure drop is a bit higher. The reactive distillation units at Jiangsu Huaihua (Xuyi) and Heilongjiang Boli are both plate towers, and they perform very well. Huaihua imports 300–700 mg of hydrogen sulfide; no hydrogen sulfide can be detected by titration methods upon export ； Boli imports hydrogen sulfide in amounts of up to 100 mg, while exporting less than 10 mg.
Our unit uses an upper layer of packing, a middle layer of bubble trays, and a lower layer of swirl plates, but the results are not good
Cyclone plate towers require a higher gas velocity! ! !
Does anyone know how well the short-path distillation units produced by Asde Company in Feicheng, Shandong work?
Compared with packed towers, vertical sieve plate towers require a smaller diameter and height, resulting in relatively lower investment costs. However, there are still few manufacturers in China that use vertical sieve plate towers for distillation. I think it might be because the packed tower operates more stably.
Friends on the second floor, do you have any contact information for Wuhan Lide Fluids? I can’t find their website online. Is there any information on the structure of nozzles or similar that you can share with us?
