Discussion on whether to install a dehydrator at the two-stage hydrogenation intermediate stage
Thread Content
In hydrodearomatization, the process starts with raw material purification, which involves hydrodesulfurization and olefin saturation, as well as side reactions that lead to oxygen removal and the formation of water. In our current plant, this water is directly sent to the subsequent dearomatization reactor. Due to the relatively low operating temperature of the dearomatization catalyst, water exists in a gaseous state at the current pressure; however, beneath the catalyst, the reaction heat causes the water to…
This will cause the temperature at the lower part of the catalyst to approach the vaporization temperature, leading to easy crushing of the catalyst. Do anyone have any good solutions?
Have you noticed that the catalyst at the bottom has become pulverized? Still guessing on your own? If the water at the bottom is in gaseous form, it probably won’t cause the catalyst to become powdered; it is usually liquid water that leads to pulverization. Therefore, it’s likely that the catalyst in the upper layer is more prone to becoming powdered
