CPL, in partnership with Solae/Dupont, Memphis Light Gas and Water, and Allied Waste, engineered, constructed and commissioned a 5000 scfm LFGTE project in under 150 days. CPL was responsible for both ends of project (i.e the Landfill Gas Processing (LGP) System at the landfill and the conversions of three boilers at the end user's site.
Project Objective:
Design/build and commission compression and dehydration plant at the Allied Waste South Shelby landfill in Memphis, Tennessee to deliver 5,000 SCFM of LFG to end user (Solae/Dupont) for use as a primary fuel in three boilers. Initial design to have expansion capabilities to final design of 8,000 SCFM with a 47 psig discharge.
Project Statistics:
- Pipeline is roughly 5 miles long
- System integration with Multiple Flare Operations
- Remote communications with end user
- Capital Costs ~ $2.75 MM
-
Based on DOE's Average US household energy usuage of 36.3 MMBtu/yr (10,660 kw-hr/yr), this project presently, offsets the equivalent energy needed to power 31,240 homes for one year
-
As of 2008, this is the largest renewable energy project for the State of Tennessee
-
CPL maintains and operates the LGP system as well as performs yearly calibrations and tuning on Solae’s three boilers
-
As a result of the success of this project, CPL was nominated as part of the Dupont team to receive two awards in 2005:
-
Engineering Excellence Award and
-
Sustainable Growth and Excellence Award.
