Following are a set of P2 options you may wish to implement. No option is perfect for everyone, but sometimes options
that have worked at one facility can work at yours. They might also serve as inspiration. |

Options below have not been reviewed by pollution prevention specialists. They are commonly recommended and
implemented for facilities. |

| Reduce Fouling Potential |
| Rag formation in the wash train and corrosion products contribute to fouling of Reboiler in the EDC process area.
To minimize this fouling, the EDC concentration of the Heavy Ends is maintained at elevated levels. Use of a static
mixer in the wash system and changing from ammonia to caustic for pH control in the C-210 and C-2210 columns
have the potential to reduce this fouling. If the fouling potential is reduced, the concentration of EDC in the Heavy
Ends can be reduced which will reduce the amount of Heavy ends generated. These changes would also reduce
the cleaning frequency of the Reboiler, which would reduce the amount of reboiler scale generated. The heavy
ends and reboiler scale are both hazardous wastes, which must be incinerated and disposed. This project has been
determined to be economically and technically feasible |
