2.5% dilute sulfuric acid at below 50°C and at atmospheric pressure. The material of the liquid inlet pipe for the equipment is 316L, with an internal flow velocity of approximately 1.5 m/s. Question: 1. Can it resist corrosion? 2: The liquid inlet pipe in the tower functions as a tubular distributor, with nozzles installed on this distributor pipe; these nozzles spray liquid onto the tower wall. Does this cause severe corrosion of the tower wall?
The main tower shell is made of 316L; according to the corrosion manual, it can be used at levels below 5% and at temperatures below 50°C.
No problem, use the pipeline materials from the ammonium sulfate process as a reference.
1. Dilute sulfuric acid can be used for pipeline transportation at temperatures below 50 degrees Celsius, with a flow rate generally required to be less than 1 m/s. 2. Considering that flow velocity and impact can damage the passivation film, the nozzle as well as the tower wall it sprays onto will be corroded, so its use is not recommended.
