Standards for removing white smoke from flue gas through catalytic cracking desulfurization
Thread Content
Which companies have implemented measures to eliminate white smoke in the desulfurization and purification of flue gases from catalytic cracking, and are there any specific standards or regulations serving as a basis for this?

Assuming that the dual-dehydration method achieves the desired results, the white smoke emitted is mainly due to water content and the phase state of water. 2. Evaluation of white smoke: 2.1. Visual assessment: It’s a complex but delicate process; the visual appearance of the white smoke is greatly influenced by the sky background and air humidity. To reduce the amount of visible white smoke, adjustments need to be made continuously, requiring “intelligent” control. Reducing white smoke comes at the cost of increased energy consumption; therefore, users need to find an acceptable balance between what they are willing to sacrifice and what they gain. 2.2. Evaluation using data: It’s simple but crude – using numerical values as indicators is easy, but the resulting sensory experience may not be perfect unless a high energy cost is incurred.
As far as I know, only local areas have relevant regulatory requirements; a national standard has not yet been issued, for reference only
