Challenge: Chevron Products Company needed to replace their existing electrostatic precipitator with a new ESP to treat the flue gas from a fluid catalytic cracker (FCC).  The new precipitator needed to meet an emission limit of 5.5 lb/hr when treating the maximum inlet load and maximum gas volume with any combination of two (2) bus sections out of service.  Their objective was to maintain continuous on-line reliability for periods of five (5) years.

 

Southern Environmental’s Solution:

Southern Environmental, Inc. provided detailed engineering, material supply, fabrication, construction, start up services and 1/10th scale physical model study for a new FCCU ESP, including new inlet and outlet duct work to connect the ESP to the existing inlet and stack.  The discharge electrodes used were SEI’s patented SEI/ELEX RS Rigid Discharge Electrodes (RDE).  Additionally a pre-fabricated Precipitator MCC Building was supplied with the housed equipment pre-installed.  The ESP consisted of a single casing with six (6) mechanical fields in the direction of gas flow and three (3) hoppers.
