Case Study

AQC guidance to reduce emissions

exhaust stack

Advisian executed the Dry Sorbent Injection Retrofit Project for AEP’s Rockport, IN, Units 1 and 2, two 1300 MW coal-fired units. This new system, in conjunction with upgrades to the existing Activated Carbon Injection System and existing precipitators, will reduce emissions of acid gases, mercury, total particulate matter, and other hazardous air pollutants.


Advisian provided balance-of-plant engineering and design services as Engineer-of-Record and with project integration responsibilities. 

In Phase I, we provided conceptual engineering and feasibility studies for project scope, schedule, and cost definition. 

In Phase II, final engineering and design were provided.  Scope included general arrangements, foundations, underground utility and fire protection piping, above-ground DSI piping and duct injection, structural steel, duct reinforcement, storm drainage, roadways, truck scale, rail modifications, grading and paving, electrical cable/wiring/tray/conduit/grounding/lighting/etc., instrumentation/control requirements and coordination including PLC to DCS conversion,  permitting support, and existing plant equipment interface. 

Services include 3D model generation and integration, development and evaluation of construction packages, vendor drawing review, FAT participation, document controls, and construction support. 


This effort ensured Rockport’s two 1300 MW coal-fired units were compliant with the EPA  MATS regulations.
