ROG Cracker

J-3 Expansion Project

Reliance Industries Limited

Main feed to ROG Cracker are the off gas streams from the adjacent two refineries.
ROGC production: 1.45 MTPA Ethylene, 133 KTA Propylene, 132 KTA Hydrogen.
Design features:
- 6 Technip Energies Technology SKM™ cracking furnaces (C₂/C₃ cracking) - 50t/h ethylene per furnace.
- Production from cracking: 960 KTA ethylene.
- 3 chilling trains combined on the same plot area.
- Ethylene and propylene refrigeration cycle common for the three trains.
