Selection of the dry absorption process
Thread Content
May I ask that, if a three-tower, one-tank, one-pump process is chosen for the dry absorption section in sulfur-based acid production, considering only the head capacity of the acid pump, is it possible to meet the requirements in China at present?
Since three towers are supplied simultaneously, the pump outlet pipes need to be enlarged accordingly; therefore, the head of the concentrated acid pump remains the same
Hehe, it’s not about the size of the equipment here – how should I answer that? But considering the current environmental situation, three towers, one tank, and one pump aren’t really a good choice, in my opinion
Three towers, one tank, and one pump may not be the best choice; it has different effects on drying and absorption. The flow rate and head of the pump might be sufficient if the installation is not very large. These days, there are many pumps with a capacity of over 2,000 cubic meters
Three towers, one tank, and one pump – it is theoretically feasible, but to date no manufacturer has adopted this approach. The design of three towers with one tank or three towers with two tanks is generally this kind.

There was once a setup with three towers and one tank, which had an impact on the exhaust gases; later, an additional tank was added for the second suction stage, so that the gas went from drying to the second suction stage and then back to the drying unit
