2007 AIR EMISSIONS INVENTORY SUPPORTING DOCUMENTATION
Emission Source ID No.:
Emission Source Description:
Process and Emission Description:
NS-K
Nafion E-Fluids Production Process
The E2 process is a batch manufacturing process. All emissions from this process
vent to the atmosphere, some via a vertical stack. The control of emissions of
certain compounds will be addressed in the attached spreadsheet.
Basis and Assumptions:
Engineering calculations using compositions, volumes and paritial pressures are used
to determine amounts vented. See attached information for assumptions made for
each vessel. A typical batch is — 220 kgs of E fluids with the following composition
(86% E2, 10% El and 4% E3).
Information Inputs and Source of Info.:

Point Source Emissions Determination:
Point source emissions for individual components are given in the attached
spreadsheet
Equipment Emissions and Fugitive Emissions Determination:
Emissions from equipment leaks which vent as stack (point source) emissions and
true fugitive (non -point source) emissions have been determined using equipment
component emission factors established by DuPont. The determination of those
emissions are shown in a separate section of this supporting documentation.
