A. TFE
Tetrafluoroethylene
Each mole of TFE/HCI distillate contains 1 mole of TFE and 2.1 moles of HCI, which calculates to:
0.566 Wt fraction TFE
0.434 Wt fraction HCL
Example of monthly calculation (by mass balance):
1. TFE Inventory Change:
Beginning Inventory 12791 kg TFE/HCl
TFE/HCI Distillate Shipment: 11948 kg TFE/HCI
Ending Inventory 7039 kg TFE/HCI
17700 kg TFE/HCI x 0.566 kg TFE _
1 kg TFE/HCI
2. TFE Usage:
TFE to Polymerization 8542.09 kg TFE
TFE to Precursors 0 kg TFE
TFE to Semi -Works 336.3557471 kg TFE
8878.445747 kg TFE

Each mole of TFE/HCI distillate contains 1 mole of TFE and 2.1 moles of HCI, which calculates to:
0.566 Wt fraction TFE
0.434 Wt fraction HCL
0.767 kg HCl for is generated for each kg of TFE used. 1 kg TFE x 0.434 kg HU _ 0.767 kg HCl
0,566 kg TFE 1 kg TFE
Example of monthly calculation (by mass balance):
1. HCI Inventory Change:
Beginning Inventory 12791 kg TFE/HCI
TFE/HCI Distillate Shipment: 11948 kg TFE/HCI
Ending Inventory 7039 kg TFE/HCI
