Irrigation – Diesel and Nat Gas

Recycling Emission Control Equipment

Recycling Emission Control Equipment from Diesel Irrigation Engines

Red Fox Resources purchases spent diesel particulate filters (DPFs) and diesel oxidation catalysts (DOCs) from diesel powered engines used to pump water from wells for agricultural irrigation.  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 Particulate Matter (PM) reduction.

Diesel engines used for pumping and irrigation in California are subject to the requirements of the local air quality management districts (AQMD) or air pollution control district (APCD) and are required to have three-way catalysts for emission controls.  Engines regulated by local air districts may be required to perform in use testing and/or emission monitoring.   Emission monitoring often results in data suggesting there has been catalyst degradation and the catalyst needs to be replaced.  Red Fox Resources purchases the spent catalyst systems that were replaced for PGM recycling.

Based on engine horsepower and application, diesel-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 diesel-powered engines are ceramic honeycomb substrates opposed to the metallic foil substrate used in natural gas engines.

Recycling Emission Control Equipment from Natural Gas Irrigation Engines

Red Fox Resources purchases three-way catalysts (TWC’s) from natural gas-powered engines used to pump water from wells for agricultural irrigation.  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.

Natural Gas engines used for pumping and irrigation in California are subject to the requirements of the local air quality management districts (AQMD) or air pollution control district (APCD) and are required to have three-way catalysts for emission controls.  Engines regulated by local air districts may be required to perform in use testing and/or emission monitoring.   Emission monitoring often results in data suggesting there has been catalyst degradation and the catalyst needs to be replaced.  Red Fox Resources purchases the spent catalyst systems that were replaced for PGM recycling.

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.

Manufacturers

Manufactures of the engines used in the power units built for irrigation pumping include:

  • Caterpillar (diesel and natural gas)
  • Cummins (diesel and natural gas)
  • John Deere
  • Deutz
  • Isuzu
  • Perkins
  • MTU
  • Volvo-Penta
  • Siemens (natural gas)

These engines may include emissions 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 parts from diesel or 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 application.  For example, Red Fox would buy a catalyst from a rich burn natural gas catalyst used in irrigation for $6 – $20 dollars per pound.
