Gachsaran Olefin Plant

Project Description

GACHSARAN OLEFIN PLANT is located at Gachsaran petrochemical complex in Gachsaran, Iran. The plant is designed to produce 1000,000 ton/year.

The ethane feed is supplied from 2nd BIDDBOLAND refinery by rate 1,270,000 ton/year. GACHSARAN OLEFIN PLANT is produced ethylene with 99.5% Min. and Hydrogen with 99.99% Min. The by-products of the plant are hydrogen rich gas (fuel gas), C3+, and light oil (Gasoline). The plant includes process unit and storage tanks divided into following units:

• Cracking Furnaces
• Hot Section and Dilution Steam Generation
• LP and HP cracked gas compression, caustic wash, drying and spent caustic treatment
• Ethylene Recovery and Purification
• Propylene and Ethylene Refrigerant Cycles
• Steam, Blow Down, Cooling Water, Fuel Gas and Other Utilities
• Ethylene Storage Tank, C3+ Storage Tank, Ethane Storage Tank, Off-spec Ethylene Storage Tank
• Fresh Caustic, Wash Oil, Sulfuric Acid Oil, and Methanol Storage Tanks
