Corrosion issues in crude benzene tubular furnaces
Thread Content
The tubular furnaces in my company suffer from corrosion frequently; how can this be prevented?
1. Ensure proper control of the ammonia washing effect; in particular, the ammonia content after the tower must be less than 50. 2. Reduce water content in the lean oil system. Not more than 0.5%. 3. Remove slag in a timely manner to reduce the scouring pressure of oil-rich substances on the furnace tubes.
The desulfurization process also needs to be properly managed, as hydrogen sulfide causes significant corrosion
Agree with what was said above. Ammonia and hydrogen sulfide in gas must be properly controlled
I agree with the person above; ammonia and hydrogen sulfide in gas must be properly controlled. The tubular furnace in our company is also severely corroded.
Moisture content is closely related to ammonia content, with hydrogen sulfide being the next factor
Severe corrosion in tubular furnaces is a troublesome issue
