Spray Dry Absorber (SDA)

Technologies under License Agreement


Originally developed in 1978

for the coal-fired boiler market

MET Lime Semi-Dry Scrubbing System


The design continues to remain a viable technology. MET recently performance tested (2015) its latest installation in Nebraska for a utility customer

Lime Semi-Dry Process Steps

Inject lime slurry spray into raw hot flue gas resulting in an efficient mass and heat-transfer process

Atomize lime slurry into a spray of fine slurry droplets -- nominally 30 - 80 micron

Results in controlled flue gas cooling by water evaporation and chemical absorption and reaction

between Ca(OH)2 and SO2 / HCl / HF in the flue gas

Forms dry particulate -- calcium salts -- as FGD reaction

by-product

By-product collected in downstream particulate collection

device for final disposal

New North American and European regulations for

particulate are requiring a Fabric Filter in lieu of an ESP
