Value Proposition - Fleet Management Why not look at LFG Equipment as a fleet? Cost of new is in the same range as mobile Equipment Relocation of LFG Equipment is possible (and same cost as new equipment) Stationary Equipment has a longer useful life than Mobile Equipment Preventative Maintenance Program extends the useful life A complete overhaul can be completed faster and cheaper than mobile Equipment
FLARES 101 – OLD SCHOOL SIZING OF A FLARE YOUR FLARE MIGHT BE TOO SMALL WHEN IT SOUNDS LIKE A FRIEGHT TRAIN WELLHEADS ARE BLOWING OFF STILL HAVE ODORS YOUR FLARE MIGHT BE TOO BIG WHEN FLARE WON’T STAY LIT AIR INTRUSION INTO THE LANDFILL
OLD SCHOOL CAPITAL PLANNING FLARE #2 FLARE #1 FLARE #3 FLARE #4 Each site fends for themselves, submits CAPEX request for new or additional flares when needed
FLARE 101 – NEW SCHOOL METHOD TO SIZE A FLARE LANDFILL GAS EMISSIONS MODEL (LANDGEM) TIES GAS EMISSIONS TO WASTE ACCEPTED AT THE GATE
Maintaining a fleet of flares may allow relocating flares between landfills at a considerable cost savings
ACTUAL PRODUCTION IS 25% TO 50% LESS THAN THEORETICAL ACTUAL DO NOT USE THEORETICAL PRODUCTION FOR 3 RD PARTY PUT OR PAY GAS CONTRACTS!
BASIC FLARE REFURBISHMENT GAS DELIVERY COMPONENTS USUALLY IN GOOD SHAPE NEW BLOWER BEARINGS/REBALANCE NEW SAFETY VALVES COMBUSTION COMPONENTS USUALLY IN GOOD SHAPE MAY NEED STEEL PATCH ON ENCLOSED FLARES or NEW SHROUD SANDBLAST, PAINT AND REINSULATE AIR LOUVER MOTORS NEW PILOT SYSTEM
BASIC FLARE REFURBISHMENT ELECTRICAL CONTROL COMPONENTS USUALLY THE FIRST TO FAIL REPLACE ALL COMPONENTS CHEAPER, FASTER, BETTER COMPLIANCE COMPONENTS NEW GAUGES, SENSORS, THERMOCOUPLES NEW DATA RECORDER RECALIBRATE OR REPLACE FLOW METER REMOTE MONITORING
COST COMPARISON New EquipmentRefurbished Equipment 4000 SCFM Enclosed Flare4000 SCFM Enclosed Flare $475,000+ $190,000 2000 SCFM Candlestick Flare2500 SCFM Candlestick Flare $242,000 $70,000 Two (2) refurbishments result in 2014 Savings of over $450,000
POINTS TO CONSIDER Your Company probably has more flares than landfills Perform inventory of flares & sizes Look at inventory as you do a fleet Plan fleet maintenance – flares will last nearly indefinitely YOY budget cycle allows ample time to plan and permit Regulatory circumstances may dictate a flare change California – No candlestick flares allowed after 2016 Local visual complaints may mean switch from candlestick to enclosed flare In some states a LFGTE Plant onsite DOES NOT eliminate need for 100% standby flare capacity Balancing LFG flow with energy plant capacity can cause problems
TAKEAWAYS Managing flares as a company fleet can save CAPEX Typical refurbishment costs 30% to 60% of new flare purchase Know the difference between theoretical and actual gas production
