Why is acid mist generated after the desulfurization tower?
Thread Content
In the coke oven gas purification stage, the electric tar catcher is turned on, while the benzene removal, naphthalene removal, and desulfurization towers are not turned on. The light transmission is still good after the electrostatic tar collector, but it becomes hazy after the desulfurization tower. What could be the reason? Is it due to benzene and naphthalene? With a benzene, naphthalene removal and desulfurization unit in operation, will it still be hazy?
Could it be benzene and naphthalene? Are there any teachers and experts from the coking industry to share their insights?
Have you studied it? Is there any impact from acid mist?
