Gas Turbine Emission Control Webinar, July 17th raised challenges
with CO and Lower Quality Fuels
The webinar yesterday addressed some of the challenges facing operators of gas
turbines.
This webinar was built on previous ones and a whole dedicated site
Gas
Turbine Emission Control - Continuous Analyses
Greg Holscher,
Sr. Applications Engineer, CERAM Environmental, Inc.
displayed a V shape configuration with reduced pressure drop.
Joshua Gillespie,
EmeraChem made some observations based on the supply of CO
catalyst to more than 40,000 MW of turbines and engines. He pointed out that VOC
removal performance varies with the compound and the emissions therefore are a
function of the mix between difficult to remove and easy to remove compounds.
Glenn C. England,
Principal Consultant, Environ International Corporation pointed
out that the removal efficiency of CO and organics is variable depending on
turbine operation and also catalyst life.
Bill Gretta, Eneractive Solutions
discussed several problem installations. The operating temperature increases
over time. In one case the rise of some 20°F was sufficient to cause emissions
to increase above the permit limits and require some adjustments.
Presentations are as follows:

The site will continue to focus on the decisions which owners need to make.
These include:
Decision Factors
Important Site Specific Aspects - How important are they?
§
Ramp rate for both peaking and combined cycle.
§
Fuels: how often is secondary fuel used? Is shale gas or lower quality gas going
to be burned?
Ability to achieve emissions goals
§
Can CO emission be achieved with water injection?
§
How difficult to meet NH3 limits?
§
Do you need HEPA filters to meet the PM2.5 limits in some areas?
Technology decisions
§
Tempering air or high temperature catalyst for simple cycle.
§
If using CO and NOx catalyst how is each positioned?
§
Urea-to-ammonia, aqueous or anhydrous?
§
Shape, pitch, and quantity of catalyst.
Regulatory changes and challenges
§
What will be the impact of NAAQS?
§
Will startup and shut down requirements for toxics translate into challenges for
turbines?
§
Trend for new construction permits.
§
What are the international regulatory trends? Where is SCR needed around the
world?
