Is it still necessary to retain traditional concrete chimneys after installing wet flue gas desulfurization in a catalytic cracking unit? I would like to discuss from the perspectives of operational management and engineering design: what are the risks associated with the new catalytic cracking units not having concrete chimneys?
Today, flue gas desulfurization towers are made of stainless steel; the use of liners in them is becoming increasingly rare
If the concrete chimney is removed, then a flue gas desulfurization tower will be needed; if non-metallic materials are to be used, there are definitely risks involved~~~
These days, chimneys with internal lining coatings are rarely used, and designs that include cement chimneys are also becoming less common. Even if you submit a design request to a design firm, online analyzers must be installed on cement chimneys in accordance with environmental regulations.
