Re: Bozeman Landfill Gas Processing Skid and Flare Assembly
Attn: Stacey Ulmen, City Clerk
Per your request, following and attached please find our Quotation to supply the described
products and services relative to your landfill project requirements for the above mentioned project.
We appreciate the opportunity to f ish this proposal.
PEI proposes ide a unitized, modular, landfill gas extraction and flare/thermal oxidizer
system, with installation by others. The gas handling system shall be able to exert a
65"WC vacuum at the inlet of the skid (70" WC vacuum at the inlet of the blower) and deliver
LFG to a 6 mrrmBtulhr enclosed flare/thermal oxidizer. The flare station*shall be sized per your i
request for quotation to handle 30 to {Max 6.0 MMBtu/hr) of landfill gas at between 20% I
and 50% methane content. � d
- Additionally the flare will thermally oxidize the SVE gas stream of 500 SCFM; 11.6 % 02, I !
11.6% CO2, 6.9% CH4, 2.5%water vapor, 67.4% Nitrogen. (Approx. 2.07 MMBtu/hr) This gas
stream will enter the flare through a separate nozzle and be combusted as it passes through the
combustion zone. At no time can the total heat input to the flare exceed 6 MMBtulhr:
ie: 6 MMBtulhr LFG plus 1 MMBtulhr SVE=6 MMBtulhr. '
The flare will be equipped with an supplementary fuel port for adding supplemental fuel-in
the future as the LFG runs out,
Vacuum/Flow control feature is accomplished with VFD blower control.
The Enclosed Ground Flare Station (EGI✓S) shall include three principal sub-systems:
o The Enclosed Ground Flare/Thermal Oxidizer l
