Without a properly designed wet stack collection system, you are at high risk for duct flooding, corrosion in the liner system, and erosion of the stack shell. 

At Verdantas, we know there isn’t a one size fits all approach to wet stacks, as the design of liquid collectors is very specific to the gas and liquid patterns of each individual wet stack. According to the EPRI Revised Wet Stack Design Guide, authored by Verdantas Flow Labs, a properly conducted wet stack study is critical to ensuring an optimized liquid collection system design.

To properly develop a liquid collection system for clients, we perform a wet stack study which consists of three key components: 

• an analytical assessment of the liquid condensation expected downstream of the wet flue gas desulfurization (WFGD) absorber;
• a physical flow model study of the absorber outlet ducting and stack liner for the development and optimization of the liquid collector and drain systems; 
• and a plume downwash study to protect the chimney from damage associated with acid corrosion and/or icing issues. 

Our Fluids Modeling team routinely designs and tests wet stack liquid collection systems for industrial and power clients to effectively capture liquid carry over and mitigate stack liquid discharge (SLD).
