| August 6, 2008 Experience with a Desiccant Siloxane Removal System Speaker:Matt Nourot, Director of Engineering, Fortistar Methane Group Presentation Description: In 2007, Fortistar Methane Group (FMG), formerly Gas Recovery Systems, LLC, installed a desiccant based siloxane removal system at the Pine Bend Electric Plant in Minnesota. The system installed at Pine Bend is the first of this type designed for continuous operation to be used for landfill gas. It is expected that this installation will prevent or reduce siloxane deposits from forming on the combustion equipment that have historically contributed to increased maintenance costs. The FMG Pine Bend plant uses a combined thermodynamic cycle consisting of two gas turbines combined with two heat recovery steam boilers. Silica deposits at this facility have been severe enough to cause the major maintenance frequency on the gas turbines to be increased by over 130%. Deposits have also lead to complete failure of the turbines. The silica deposits are the result of combustion of siloxanes in the landfill gas. In 2007, FMG approved the purchase of two domnick-hunter GES 600 siloxane removal systems. The domnick-hunter system is comprised of two GES 600 systems each with two desiccant towers automated to regenerate the media with heated air. FMG has also installed a John Zink offgas flare to combust the residual non-methane organic gases removed during the regeneration process. This paper discusses the history of the Pine Bend plant, the design and installation of the desiccant system, and its performance based on siloxane removal. | |

| August 13, 2008 How Fast is Too Fast: What is the True Maximum Velocity? Speaker:Juene Franklin, Riley, Park, Hayden & Associates Presentation Description: For many years the industry has used velocity as one of the most important parameters to establish acceptable pipe sizes for the Landfill Gas Collection and Control System (GCCS) Pipe Networks. Many LFG Designers have employed Velocity Rules to define acceptable velocity ranges to handle concurrent and countercurrent flow. Though everyone understands the importance of accurately determining LFG pipe velocity requirements, different designers tend to employ different Velocity Rules. Additionally, there is no detailed information available concerning the origin of these Velocity Rules. This presentation will discuss tests used to ascertain the appropriate Velocity Rules to employ in GCCS pipe design. The presentation will also discuss guidance on how to implement these rules in a manner that adheres to the fundamental laws of fluid mechanics once the Velocity Rules have been established. | |

| August 20, 2008 Considerations for the Landfill Owner/Operator Prior to GHG Market Participation Speaker:Jim Michelsen & Chad Leatherwood, PE, SCS Engineers Presentation Description: SWANA’s July four part e-session series focused on greenhouse gas (GHG) market mechanisms and how they apply to eligible landfill carbon projects. This e-session will build upon the GHG themes presented in the July carbon series, focusing on factors a landfill owner/operator with a potential GHG reduction project should consider when defining a path forward. Particular attention will be given to technical issues for those sites with LFG collection systems (or contemplated the installation of one) to preserve or “bank” vintage GHG credits in advance of deciding how to proceed on implementing a carbon project. Specific attention will be given to considerations for establishing effective programs for monitoring, calibration, and recordkeeping. | |
