Met - Model WFGD -Lime-Based Process System

Gypsum Production From Lime-Based WFGD Processes By MET. Lime provides higher SO. The highly alkaline reagent results in reduced Liquid-to-Gas (L/G) ratio and therefore reduced power consumption relative to limestone-based scrubbing. The higher reactivity of lime requires less retention time, reducing size and cost of the reaction tank. Lower L/G (lower power) than limestone WFGD. Utilizes smaller tank size due to requiring less reaction tank retention time. Site specific economic factors may favor lime over limestone WFGD.
