CleanAIR Systems of Santa Fe, NM, announced the introduction of a new E-POD™ selective catalytic reduction (SCR) emission control system. Seven E-POD systems were installed on drill rigs operating in Wyoming’s Pinedale Anticline Project Area (PAPA).
The technology combines CleanAIR’s zeolite-based SCR catalyst, a diesel oxidation converter or a diesel particulate filter, and a reductant mixing system into one silencer package. Working in conjunction with Caterpillar dealer Wyoming Machinery Company, custom-engineered E-PODs using diesel oxidation converters were installed on seven diesel generators with Cat 3512 engines between September 2008 and January 2009 at PAPA.
An innovative design was developed for several of the E-PODs to facilitate easy moving of the system when relocating to a new drill site. A typical SCR system often requires dismantling, placement on a flatbed and hauling to the next drill location, where it is reassembled and once again lifted into place. The E-POD system, on the other hand, is installed above the generator, becoming part of the trailer’s roof and enabling it to be transported along with the generator.
The E-POD system can provide compliance with EPA Tier 4 emission standards (version with the particulate filter), as well as with New Source Performance Standards (NSPS) for lean-burn natural gas engines.
