Key Takeaways
- Agree the emissions reference condition before selecting equipment
- Match the catalyst and dosing system to the real exhaust envelope
- Plan reagent safety, access, monitoring and catalyst service
Technical guide introduction
Selective catalytic reduction uses a reagent such as urea or ammonia and a catalyst to reduce nitrogen oxides. Application depends on engine-out emissions, exhaust flow and temperature, oxygen reference, duty cycle and the required limit.

Six-Step Project Guide
Step 1
Agree the emissions reference condition before selecting equipment
Selective catalytic reduction uses a reagent such as urea or ammonia and a catalyst to reduce nitrogen oxides. Application depends on engine-out emissions, exhaust flow and temperature, oxygen reference, duty cycle and the required limit.| Input to confirm | Guide context |
|---|---|
| Agree the emissions reference condition before selecting equipment | Planning Guide |
| Match the catalyst and dosing system to the real exhaust envelope | Project Planning |
| Plan reagent safety, access, monitoring and catalyst service | 11 minutes |
Step 2
Match the catalyst and dosing system to the real exhaust envelope
Brochure figures are source references, not universal guarantees. Final emissions and ammonia-slip obligations are confirmed for the engine, fuel, site and test basis. Agree the emissions reference condition before selecting equipment
Match the catalyst and dosing system to the real exhaust envelope
Plan reagent safety, access, monitoring and catalyst service
Engine model, fuel, rating, duty cycle, exhaust flow, temperature and engine-out emissions
Applicable NOx and ammonia-slip limits, oxygen reference, test method and permit condition
Load range, annual hours, starts, low-load operation and available warm-up strategy
Step 3
Plan reagent safety, access, monitoring and catalyst service
How to define engine-out emissions, exhaust conditions, reagent, controls, catalyst and test basis for a diesel-generator SCR system.Agree the emissions reference condition before selecting equipment
