Natural Gas Compression Engines

Recycling Emission Control Equipment

Recycling Emission Control Equipment from Gas Compression Equipment

Red Fox Resources purchases three-way catalysts (TWC’s) from natural gas compression engines used in natural gas production, compression, and transportation.  These engines may operate under the requirements of EPA’s Reciprocating Internal Combustion Engine National Emissions Standards for Hazardous Air Pollutants (RICE-NESHAP) and/or local emission control requirements that require the use of a platinum group metals (PGM) based emission control catalyst for NOx and CO reduction.

Based on engine horsepower, application, and fuel source, natural gas-powered engines may be equipped with a variety of catalyst technologies and formulations to meet the emission standards required.  Generally, the emission control catalysts utilized in natural gas-powered engines are metal foils opposed to the honeycomb type substrate used in diesel and gasoline engines.


We have experience recycling catalysts from a variety of natural gas compression systems including:

  • Drilling: internal combustion engines used to power drilling rigs
  • Producing: internal combustion engines used on producing wells and/or that power compression facilities used in gathering natural gas
  • Processing:  Plants that compress natural gas and process it for recovery of natural gas liquids

Similar to on-highway or stationary diesel applications, there are various scenarios that cause catalyst degradation requiring the in the emission control technology to be replaced during the useful life of the engine.  Red Fox actively purchases these spent emission control parts from natural gas compression engines from dealers, end users and manufacturers.


Common engine and equipment manufacturers in which Red Fox recycles stationary natural gas emission control parts include:

  • Caterpillar
  • Cummins
  • Jenbacher
  • Waukesha
  • Arrow

These engines may include catalyst packages from the following emission control manufacturers that Red Fox actively purchases back for recycling.

  • Advanced Catalyst Systems
  • Catalytic Combustion Corporation
  • DCL International
  • Emissions Controls and Silencers
  • Johnson Matthey
  • Miratech
  • Precision Catalyst
  • Synergy Catalyst

The value for these spent catalysts from natural gas equipment ranges from $25 – $2,000 and Red Fox typically buys this material by the part number or by the pound based on the application.
