DERRICK
Derrick type stacks are one type of support system for an elevated flare. The elevated flare tip
is mounted on top of a riser supported by a steel trussed (derrick) structure. Derrick supported
flares require three or four additional foundations for the derrick legs, but this is a
relatively smaller plot space when compared to a guyed flare of the same height. Derrick flares
eliminate process temperature design concerns. Additionally, a single common derrick structure
can support multiple flare risers.
