General explanation:
Semi -works is a research & development area that operates under a wide range of conditions. Emissions are calculated for each individual
campaign. These campaigns fall into two categories. One is polymerization campaigns and the other is slurry reclaim campaigns. In both
cases, material balance is used to determine emissions. Since all emissions occur within the semi -works facility, there are all assumed to
be point source emissions via the process stack SW-1. The only emissions calculated for SW-2 are acid fluoride emissions
associated with running melt flow samples under the lab hood.
Polymerization Campaign Emissions Determination:
The production and raw material information is entered for each campaign on a worksheet. The individual sheets in this workbook
are copies of the completed worksheets for each campaign. Data in green fields is entered when applicable for the polymerization campaign.
The other cells are calculated cells. The emissions for the campaign are calculated at the bottom of the worksheet. For the annual
emissions calculations, the emissions from these campaigns are totaled onto a summary sheet. In this workbook, that is called
"Campaign Summary". A summary by month is found on "Year End Summary".

Example Mass Balance Calculations for polymerization campaigns: (using 4-SXF-2.1 worksheet for example)
The emissions are determined by mass balance around the system. Data used in the calculation is obtained from production records and
entered into the worksheet. The following is entered into the worksheet after each campaign:
1) Enter the starting material at the beginning of the campaign. This would include any material in the recovery tank and condensate
tank. The composition of the material in each tank is determined by lab analysis and/or on-line GC.
2) Enter the amount of initiator added to the system, based on integrator on initiator feed. The concentration of initiator is determined
by lab analysis.
3) Enter the amount of TFE added to the system, based on the integrator for TFE feed.
4) Enter the amounts of solvent (E2, F113) and monomer (PSEPVE) added to the system during the campaign. Drum weights
before and after the campaign are used to determine this.
Enter starting and addition data as described in steps 1-4 above in the green shaded areas.

Example Mass Balance Calculations for slurry reclaim campaigns:
The slurry reclaim process is used to recover valuable solvent and monomer from drums of polymer slurry. The semi -works flash dryer
is used to flash off the solvent and monomer liquid into a vapor state, so that the solids can be collected in a bag filter. The vapors are then
condensed back into liquid which can be reclaimed. Due to a high nitrogen (noncondensible) flow, some of the solvent and monomer escapes
the condenser as vapor to the SW-1 stack. A mass balance approach is used to determine how much vapor has been lost, so that this can
be included in annual air emissions summary.
Here is a summary of the material balance calculation.
1) Weight of drums processed through the system are recorded. The reported composition of the drums is used to determine
VOC and F113 content. Drums were determined to have 35% solids or other non -recoverable waste, based on a material balance on
solids (polymer and waste collected).
2) Any fresh E2 solution used for startup of the flash drying system is accounted for in the balance.
3) Outputs include weight of reclaimed liquid collected in drums, weight of solid polymer collected, and weight of solid waste
in drums.
