“Feedstock” means the raw material supplied to a process.
“Final point of delivery” means the last point of delivery for a given electricity transaction.
“Flare” means a combustion device that uses an open flame to burn combustible gases with combustion air provided by uncontrolled ambient air around the flame. This term includes both ground-level and elevated flares. When used as a verb, the term “flare” means to combust vent gas in a flare.
“Flexicoking” means a thermal cracking process which converts heavy hydrocarbons such as crude oil, tar sands bitumen, and distillation residues into light hydrocarbons.
“Flexigas” means a low Btu gas produced during flexicoking.
“Fluid catalytic cracking unit” or “FCCU” means a process unit in a refinery in which petroleum derivative feedstock is charged and fractured into smaller molecules in the presence of a catalyst, or reacts with a contact material to improve feedstock quality for additional processing, and in which the catalyst or contact material is regenerated by burning off coke and other deposits. The unit includes, but is not limited to, the riser, reactor, regenerator, air blowers, spent catalyst, and all equipment for controlling air pollutant emissions and recovering heat.
“Fluid catalytic cracking unit regenerator” means the portion of the fluid catalytic cracking unit in which coke burn-off and catalyst regeneration occurs, and includes the regenerator combustion air blower(s).
“Fluid coking” means a thermal cracking process utilizing the fluidized- solids technique to remove carbon (coke) for continuous conversion of heavy, low-grade oils into lighter products.
“Fly ash” means particles of ash, such as particulate matter that may also have metals attached to them, which are carried up the stack of a combustion unit with gases during combustion.
“Fossil fuel” means a fuel, such as coal, oil, and natural gas, produced by the decomposition of ancient (fossilized) plants and animals.
“Fuel” means solid, liquid or gaseous combustible material.
“Fuel analytical data” means any data collected about the mass, volume, flow rate, heat content, or carbon content of a fuel.
