摘要

Transient reciprocating engines are utilized on a variety of applications from drilling rigs to spinning and non-spinning reserve power plants that are utilized to back up a power grid rely- ing on variable sources such as wind and solar. These engines range from 500 kW to 20+ MWs utilizing diesel, natural gas, crude oil, heavy fuel oil, or dual fuel. The transient nature of these engines creates very challenging engine emissions profiles that swing significantly based on the engine load and fuel composition. With the ever tightening environmental regulations in the United States requiring ultra-low (<5 ppm) NOx emissions and growing focus on the limitation of ammonia slip, a criteria pollutant precursor, the design of the emissions treatment system becomes a key consideration to a project’s viability. Hug Engineering has SCR installations on nearly 2,000 MW of capacity on transient applications. The systems utilize a variety of reactor design and configurations, a combination of catalyst (SCR, Oxidation, Ammonia slip) material based on the regulation requirements, and state-of- the-art control systems to achieve Ultra-Low NOx performance all while minimizing NH3 slip. Validated performance includes: 1. Up to 99% NOx reduction (<2.3 ppm at 15% O2) 2. >90% CO and unsaturated hydrocarbon reduction 3. <1 ppm ammonia slip 4. PM < 0.03 g/kWh (Tier 4). This performance is not just achieved at steady-state, measured through planned periodical static tests at near full load conditions, but it is also proven with systems having Continuous Emissions Monitoring systems (CEMs) installed requiring “continuous” (15 minute block av- erage) compliance. This presentation will be geared around the control strategy and catalyst combinations necessary to meet ultra-low emissions on dynamic engines with swinging emissions.

PM <0.03克/千瓦时（第4层） 。这种性能不仅在稳态上实现，通过近乎全载条件进行了计划的周期性静态测试来测量，但也可以通过安装连续排放监测系统（CEMS）的系统来证明，需要“连续”（15分钟阻止AV-erage ） 遵守。本演示文稿将围绕控制策略和催化剂组合，以满足具有摆动排放的动态发动机的超低辐射。
