1.Provide emergency power supply to enable circulation flow over EO storage cooler at power
Trip.
2.Independent refrigeration unit.
3.Details to be finalized at detail engineering stage.
4.The vent line to vent absorber shall be continuously purged with nitrogen to prevent stagnant EO.
5.For safety reasons HPEO product line and vent gas line between process area and HPEO storage area preferably to be underground piping. These pipelines can be put on pipe rack if the following conditions are met:
-Sloping towards the storage vessel/vent absorber.
-No pockets or dead ends.
-If pocket cannot be avoided,provide drainage and appropriate flushing facility.
-Properly insulate for cold insulation and fire protection.
-Not to be exposed to high temperature surfaces.
-Must be located with minimum vulnerability for damage by by external sources,IE,the highest
level in the pipe rack.
-To be fully welded.
6.Continuous flow is required to prevent stagnant EO.
7.Double block and bleed valve with automatic backflow protection to be installed on N2 supply.
8.Road cars to be fully dedicated to EO service to prevent contamination.
9.PSV-8324 outlet to be routed back to EO storage vessel.
10.Sprinkler system shall be activated by fire detection system.
11.To be copied by dec based on package vendor input.
