Section 215.521  Definitions

In addition to the definitions of 35 Ill. Adm. Code 211, the following definitions apply to this Subpart:  

            "Air Oxidation Process":  any unit process including ammoxidation and oxychlorination which uses air or a combination of air and oxygen as an oxidant in combination with one or more organic reactants to produce one or more organic compounds.

            "Cost Effectiveness":  the annual expense for cost of control of a given process stream divided by the reduction in emissions of organic material of that stream.

            "Flow (F)":  Vent stream flowrate (scm/min) at a standard temperature of 20C.

            "Full Operating Flowrate":  Maximum operating capacity of the facility.

            "Hourly Emissions (E)":  Hourly emissions reported in kg/hr measured at full operating flowrate.

            "Net Heating Value (H)":  Vent stream net heating value (MJ/scm), where the net enthalpy per mole of offgas is based on combustion at 25º C and 760 mm Hg, but the standard temperature for determining the volume corresponding to one mole is 20º C, as in the definition of "Flow."

            "Process vent Stream":  an emission stream resulting from an air oxidation process.

            "Total Resource Effectiveness Index (TRE)":  Cost effectiveness in dollars per megagram of controlling any gaseous stream vented to the atmosphere from an air oxidation process divided by $1600/Mg, using the criteria and methods set forth in this Subpart and Appendices E and F.
