Emissions Control Solutions
Midstream and LNG
Natural gas pipeline compressor stations and LNG facilities rely on Peerless emissions management solutions to keep NOx, CO and VOC emissions within permit limits on the combustion turbines that drive compression, liquefaction and on-site power. Every Peerless system is engineered around the turbine, the site and the permit, whether the need is a new system or a retrofit to equipment on site.
From the Compressor Station to the Export Terminal.
Midstream Applications Peerless Serves
Natural Gas Pipeline Compressor Stations
Compressor stations need dependable emissions control that keeps gas moving. At a pipeline compressor station Peerless supplied a complete SCR system for three turbine units that reduce NOx from 25 ppm to 2.5 ppm with ammonia slip below 5 ppm. Each system included an SCR reactor with space for a future CO catalyst, a Peerless EDGE® ammonia injection grid, a 2×100% tempering air fan package, an ammonia flow control unit, a continuous emissions monitoring system and a Peerless PLC control system, with a single 10,000-gallon aqueous ammonia storage tank sized for all three units.
LNG Facilities
LNG facilities combine large turbine trains, tight emissions limits and demanding schedules. For an LNG expansion in Maryland, Peerless engineered CO and SCR systems for two Frame 5 turbines, reducing NOx from 25 ppm to 2.5 ppm with ammonia slip below 5 ppm and CO and VOC each below 2 ppm. The scope ran from the turbine outlet expansion joint to the stack, including the patented Peerless EDGE® AIG, CO catalyst, SCR catalyst, silencers, damper, heat recovery unit, tempering air, ammonia flow control unit and reagent storage and handling. Modularized components simplified erection on site.
At the same facility, a CO and SCR system for a 15 MW turbine serving the air separation unit reduced NOx from 25 ppm to 5 ppm, with CO and VOC each below 2 ppm.
For an LNG export facility in Louisiana, Peerless delivered an expedited replacement of SCR and CO catalyst, including sample testing, emissions data analysis and field support, along with SCR reagent storage and handling systems that include a 40,000-gallon tank and pump skid.
Gas Turbines and IC Engines
Peerless solutions are applied to the gas turbines and IC engines found across midstream operations. Peerless Direct Injection SCR injects a urea or ammonia-based reagent into the exhaust gas of a boiler, furnace, turbine or IC engine, delivering NOx and CO reduction of 95%+ without vaporization equipment such as fans and electric heaters.
Retrofit Options for Existing Equipment
With expertise in total SCR system design and optimization, Peerless helps operators meet NOx emissions regulations while working within existing infrastructure and avoiding unnecessary maintenance costs and outages.
Retrofit Solutions Include:
Replacing ammonia injection grid lances with the patented EDGE® AIG design to reduce ammonia consumption by 20-40% and extend catalyst life by 1-2 years
Converting conventional vaporizer systems to direct injection and reagent conversion
Rebuilding or upgrading AFCU and vaporizer skids, including controls upgrades
Catalyst testing, cleaning, replacement and storage
In-house CFD modeling and flow analysis, including tempering air optimization at the catalyst
Complete Exhaust System Scope
Midstream and LNG projects often need more than catalyst. Peerless and its CECO Environmental sister brands can supply the complete exhaust path, from the turbine outlet to the stack, emissions and noise compliance engineered together.
