Olefin Production Solutions
Accurate and precise temperature is needed to maintain
optimum furnace performance and prevents undesirable side
reactions. Temperature proles applied along the cracking
coil are designed to avoid long residence times at low
temperatures. Low temperatures favor reactions involved in
the formation of secondary products, thereby reducing olen
yields. The burner fuel control valves regulate the temperature
of the furnace by controlling the fuel supplied to the burners.
Due to the location by the furnace, burner fuel control valves
may be exposed to high ambient temperatures. Emissions
from fuel gas can be an environmental concern and must be
accounted for in packing design.
