Before the use of the portable trailer flare, the
pipeline natural gas

was vented. The venting of natural gas is 23 times
more damaging

than the CO2 produced by burning the natural gas.

Texas Eastern Pipeline used a combination of gas recompression/transfer

(if a second pipeline was near by) and flaring (when no
second pipeline

was available or when the pressure was too low for
recompression) to

reduce emissions -- quite progressive company for the late
1980's.

First section of pipeline being serviced with portable
trailer flare.

Texas Eastern and the local fire companies were all
very concerned and

Cautious about the flare operation (heat, flame, radiation,
noise, safety).

NAO worked with Texas Eastern and the local fire/county authorities
to

explain the trailer flare's operation, design and safety features.

Once the trailer had been connected & operation
started both Texas Eastern

and the local officials gained confidence. The
flare could be located fairly

close to buildings since it was elevated (80') and
the heat/thermal radiation/noise

with the MULTI TIP FLARE BURNER were minimal.

The MULTI TIP FLARE (NMEC -- NAO Multi External Coanda
"HOT DOG" Tip) uses

long horizontal "T" shaped burners (24
for this case) to spread out the natural gas

over a wide area (about 8'
diameter) in order pull in and mix with air for combustion

. . . . producing a
short clean flame with reduced visibility.

Each HOT DOG burner has about 72 vertical holes or jets
to pump in air and mix with

the air, these many small holes also act to reduce
overall noise from the gas flow. <
