Emission Source ID No.: NS-F
Emission Source Description: Nafion MMF Process
Process and Emission Description:
The MMF process is a batch/semi-batch manufacturing process. All emissions from
this process vent to the Nafion Division Waste Gas Scrubber (WGS), Control Device ID
No. NCD-Hdrl, which has a documented efficiency of 99.6%. The control of emissions
of certain compounds will be addressed in the following spreadsheets. Some
compounds (i.e. TFE) pass completely through the scrubber, therefore the efficiency is
assumed to be zero percent (0%).
Basis and Assumptions:
The MMF process flowsheets #9599 and #5600 are used as a basis for relative
compositions and flow rates of vent streams to the division WGS. A 7.2 kg/hr
maximum MMF production rate is used as the basis for maximum vent rates.
Information Inputs and Source of Inputs:

Point Source Emissions Determination:
Point source emissions for individual components are given in the following pages. A
detailed explanation of the calculations are attached.
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 seperate section of this supporting documentation.
