Precautions for WSA furnace drying
Thread Content
Why, during the drying process of the Topsoe wet acid production WSA condenser, it is not possible to install a blind flange at the acid outlet at the bottom of the WSA condenser; instead, the pipeline must be filled with water or sulfuric acid to protect it. How can one determine that the water level is sufficient to protect the entire pipeline?
It’s probably because the material of the acid outlet pipeline isn’t heat-resistant.
The key question is why isn’t the acid outlet isolated with a blind flange, and why must a medium be poured in to isolate that section of the pipe?
We have over 10 years of practical experience in the full domestic production of acid-making WSA condensers; as early as 2004, we completed China’s first project for the domestic production of such condensers. To date, we have completed over 20 full-scale domesticization projects in China (involving the manufacturing of spare parts such as covers, mist eliminators, foam removers, glass tubes, tube sheet assemblies, and bottom acid tanks, as well as the related demolition and installation work). Meanwhile, we have improved the material properties of key spare parts, which has earned us high recognition from our clients. Phone: 18873309860 WeChat: 18707332008
During furnace drying, a large amount of water vapor is generated, which condenses into water after passing through the condenser. If a blind flange is installed at the acid outlet of the condenser, the water will accumulate at the bottom of the condenser as there is no outlet for it to flow out, which can easily damage the acid-resistant bricks. Over time, corrosion and leaks may occur at the bottom of the condenser.
