ESP Particulate Collection

Catalytic Reduction for NO control) the ESP has been placed both before and after the SCR. 

The ESP operates with a low pressure drop making it suitable for installation on existing nnits with pressnre constraints snch as CO boilers. The typical ESP will require less than 2 w.c. additional pressnre drop, which is typically less than that of a TSS or WGS. 

FCC fine gas laden with catalysts tines enters the ESP in a uniform flow pattern between parallel collecting plates into an area of high voltage. 

When the particles reach the bottom of the collection plate they fall into a hopper for subsequent evacnation into a collection device snch as a dumpster or are pneumatically transported to a storage silo for storage and disposal. Because of their fine natnre, these particles are not typically reintroduced into the FCCU for rense.
