The EKATO HWL Side-Entry Agitator for Flue Gas Desulfurization (FGD) is designed for use in absorber towers within flue gas desulfurization plants. As a side-entry agitator configuration, the HWL FGD is applied where vessel geometry, process requirements, and absorber tower layout call for lateral agitator installation rather than a top-entry arrangement.
This agitator family is engineered around the demands of FGD absorber service, including dynamic loading considerations tied to rated motor power. EKATO identifies the HWL FGD as a purpose-built agitator for absorber towers and lists product-specific details such as motor power range, shaft diameter range, operating pressure range, impeller systems, and wetted material options for this equipment.
The HWL FGD design may include the EKATO 42L mechanical seal, described by EKATO as a single-acting, product-lubricated cartridge mechanical seal for FGD side-entry agitators. EKATO also identifies a shut-off device that allows mechanical seal servicing or replacement without shutting down or emptying the absorber tower.
For impeller configuration, EKATO lists WINGJET and propeller systems, with WINGJET developed for absorber use in flue gas desulfurization plants.
