Main Findings

• The Separator B, oily water level control valve LDV31160B shall be increased in the port size diameter flow capacity from CV=56 to a New valve CV= 150, in order to cover the de-rating pressure to 22.5 Barg.

• A new set point was provided to be 32 barg for the PSV’s of separator B, New Datasheet has been calculated (IFR) and the results are pointing out a change in the following items:

3 New PSV’s (1,2,3) Type according API526 is: 8T10

Inlet pipeline reducer: 12”x8”

Outlet full bore block valve: 10”

Outlet pipeline expander 20”x10”

Main Findings

• The Separator B, Pressure Control valve gas to Flare header PV31111B shall be increased in the port size diameter flow capacity from CV=260 to a New valve CV= 900, in order to cover the de-rating pressure to 22.5 Barg.

• The Separator B, Oil level control valve LV31105B and the Flow control valve FV31113B do not need a change/replacement for the de-rating pressure to 22.5 Barg.

• Separator B capacity Datasheet (IFR) shows the separator capacity suitable for the de-rating pressure to 22.5 barg.

CONCLUSIONS

• Separator B capacity check DATASHEET (IFR) at 22.5 barg, shows no limitation for a maximum of 4 lines from loops 10, 20 and 30, reservoir A.

• PSV 1,2,3 on Separator B, have been designed to protect the vessel for a block outlet scenario with Set Point=93 barg. The request change in Set Point to 32 barg, needs the following equipment list to change/replace :

• 3 New PSV’s (1,2,3) Type according API526 is: 8T10.

• Inlet pipeline reducer: 12”x8”

• Outlet full bore block valve: 10”

• Outlet pipeline expander 20”x10”

CONCLUSION CONT…

• The Separator B, PV31111B and LDV31160B shall be increased in the port size diameter flow to cover the de-rating pressure at 22.5 Barg.

• The Separator B, LV31105B and FV31113B do not need a change/replacement for the de-rating pressure at 22.5 Barg.
