Dahej

Dahej Manufacturing Division located near Bharuch, Gujarat, is spread over 1,778 acres. It comprises of an ethane / propane recovery unit, a gas cracker, a caustic chlorine plant and 4 downstream plants, which manufacture polymers and fibre intermediates.

The complex has its own facility for separating ethane/propane from rich gas containing recoverable amounts of ethane / propane purchased from GAIL. The lean gas from which the ethane / propane has been extracted is returned to GAIL. The ethane / propane mixture is then used as a feedstock for the gas cracker plant.

The complex was commissioned in two phases in order to rationalize cash flows and level of borrowings. The Caustic Chlorine, VCM and PVC pants in phase one was commissioned in 1997. After this, in phase two, HDPE plant, MEG plant, ethane / propane recovery plant and gas cracker unit were commissioned in 2000.
