Expression of Interest (EOI) for Alternate Evacuation of Ethane-Propane Mixture from Uran Plant (District: Raigad in Maharastra state) to OPaL (District: Dahej in Gujarat state)

Oil and Natural Gas Corporation Limited (ONGC) is India’s premier organization engaged in exploration/ exploitation of hydrocarbons and has large infrastructure of off shore platforms, submarine pipelines and shore terminal facilities. Crude oil and associated gas produced at Mumbai Offshore fields are transported to Uran Plant, Uran (District Raigad in Maharastra state) for further processing. Uran Plant is one of the most unique, vital and environmentally friendly oil and gas processing complex.

Uran Plant presently receives approx. 12 mmscmd of Natural gas from Mumbai Offshore fields and extracts products like LPG, Naphtha and C2C3 mixture. Prior to the recovery of products, the gas is sweetened to make it free from Hydrogen Sulphide (H2S) and Carbon-di-Oxide (CO2)

Requirement:

Product C2C3 is a mixture of Ethane and Propane extracted from Natural gas consisting mostly C2 and C3 with minor presence of C1, C4 and C5. A typical composition is given below.

Component % WT (Average)

C1    0.5
C2    63

C3    33

i-C4    2.0

n-C4    1.5

i-C5    0.04

n-C5    0.01

At present this product is supplied to Petrochemical Manufacturing Plant of M/s RIL’s at Nagothane (District: Raigad in Maharastra state) through pipeline. A Petrochemical Unit of ONGC is being set up at Dahej district in Gujrat state and Uran plant is looking for best mode of transportation of C2C3 mixture from Uran to Dahej.
