Air distributor clogged
Thread Content
In our company’s 180,000-ton hydrogen peroxide production project, the air distributor used for feeding oxygen experiences blockages on multiple occasions during startup. The inlet pressure is high while the flow rate is low; as operation continues, the pressure gradually decreases while the flow rate increases. This phenomenon is particularly noticeable when starting up in cold weather. What causes it, and are there any preventive measures?
It is recommended to adjust the air temperature to 40–50°C, and to inject aromatics into the air distribution pipes of the oxidation tower using a plunger pump; this should have some effect
When driving, it might be due to a low temperature in the oxidation tower or impurities in the pipes
Can a pipe filter be installed on the intake pipeline?
