ONGC OPAL SIL STUDY & SIL VERIFICATION SUMMARY

OPaL had developed an offsite storage facilities which consist of two Double walled Ethylene Storage Tanks, associated pumps and vapour handling equipment for cryogenic storage and transfer section. During operation, Ethylene produced and vaporised in the Dual Feed Cracker Unit is directly fed to the polymer units with only a small flow of liquid to the storage tanks. The units involved as part of project scope were

• DOUBLE WALLED ETHYLENE STORAGE TANKS
• ETHYLENE IN-TANK PUMPS
• ETHYLENE FEED PUMPS

RCSPL conducted SIL Study and SIL verification for the project
