CONFIGURABLE AFTERTREATMENT SYSTEMS INCLUDING A HOUSING - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240044272 titled 'CONFIGURABLE AFTERTREATMENT SYSTEMS INCLUDING A HOUSING

Simplified Explanation

The abstract describes an aftertreatment system for treating exhaust gas. The system includes a housing with two internal volumes, an oxidation catalyst in the first internal volume, a filter in the first internal volume, at least one selective catalytic reduction (SCR) catalyst in the second internal volume, and a decomposition tube in the second internal volume.

  • The system has a housing with two internal volumes.
  • The first internal volume contains an oxidation catalyst, which receives a portion of the exhaust gas through an inlet conduit.
  • The first internal volume also contains a filter, which emits the exhaust gas into the second internal volume.
  • The second internal volume contains at least one SCR catalyst, which is perpendicular to the first axis.
  • The second internal volume also contains a decomposition tube, which is parallel to the third axis.

Potential applications of this technology:

  • Automotive industry: This aftertreatment system can be used in vehicles to reduce harmful constituents in exhaust gas, such as nitrogen oxides (NOx), carbon monoxide (CO), and particulate matter (PM).
  • Power plants: The system can be implemented in power plants to reduce emissions and comply with environmental regulations.

Problems solved by this technology:

  • Emission reduction: The aftertreatment system effectively reduces harmful constituents in exhaust gas, improving air quality and reducing environmental impact.
  • Compliance with regulations: The system helps vehicles and power plants meet emission standards set by regulatory authorities.

Benefits of this technology:

  • Improved air quality: By reducing harmful constituents in exhaust gas, the system contributes to cleaner air and better public health.
  • Environmental sustainability: The aftertreatment system helps reduce the environmental impact of vehicles and power plants by minimizing emissions.
  • Regulatory compliance: Implementing this technology ensures compliance with emission standards and avoids penalties or fines.


Original Abstract Submitted

an aftertreatment system for treating constituents of an exhaust gas includes: a housing defining a first internal volume and a second internal volume; an oxidation catalyst in the first internal volume and extending along a first axis, the oxidation catalyst configured to receive at least a portion of the exhaust gas via an inlet conduit fluidly coupled to the oxidation catalyst; a filter in the first internal volume and extending along a second axis parallel to and offset from the first axis, wherein an outlet of the filter is disposed within the second internal volume and configured to emit the exhaust gas into the second internal volume; at least one selective catalytic reduction (scr) catalyst in the second internal volume and extending along a third axis that is perpendicular to the first axis; and a decomposition tube in the second internal volume in a direction parallel to the third axis.
