A large boiler company required a FGD system for two, 200,000 lbs/hr fuel oil boilers for a refinery in Mexico. Macrotek competed with major air pollution suppliers and succeeded to win the contract. The scope included two spray towers, all auxiliary components, pumping packages, a forced oxidation system, piping, and controls.
In addition, integral stacks were included for the overall height of 200 feet. Structural design was particularly challenging as the installation is in an active seismic zone with hurricane wind conditions. Lime slurry is used as a reagent and the system was completed in 2004.
