0830 hrs

0930-1145 hrs Purged and recovered P11 from all system pipelines, low spots, filters and internal pumping systems.

Continued recovery process from P11 tanks at freezing point –110,5 deg C

Simultaneously P11 tanks were purged with warm N2 with a rate of 220 CBM/hr

• •

1400 hrs

516 kg P11 recovered and pumped to 2nd collecting tank

1415 hrs

Measured P11 content in both P11 tanks and piping system with Dräger tubes, type for Halogonated Hydrocarbons100/a. No indication of P11 was detected on the tubes which corresponds to less than100ppm.

1415 hrs

Approximately 3,5 tons of N2 were consumed for P11 recovery. We estimate P11 tanks having been purge with 1000 CBM N2. With this ammount N2 throughput P11 remenants is less than 3 PPM.
