Reliance Gas Pipelines Limited (RGPL) Part- I: Rs.1,428 crore pipeline project on the anvil
Reliance Gas Pipelines Limited (RGPL), a wholly owned subsidiary of Reliance Industries Limited (RIL), proposes to build and operate a 486 km long pipeline for transportation of hydrocarbon liquid (Ethane) at a cost of Rs. 1,428 crores.
The pipeline will transport liquid made available from RIL�s Dahej Manufacturing Division to RIL�s Hazira Manufacturing Division and to RIL�s Nagothane Manufacturing Division.
The dedicated pipeline network, named as Dahej - Nagothane Ethane Pipeline (DNEPL) is designed to transport 1.25 MMTPA of ethane which is equivalent to 159 TPH ( 89 TPH for NMD and 70 TPH for HMD) of liquid Ethane.
DNEPL will originate from Dahej in Gujarat and terminate at Nagothane in Maharashtra with a spur pipeline to Hazira.

Reliance Gas Pipelines Limited (RGPL) Part- II: Details
The length of the mainline from Dahej to Nagothane is around 440 km. Approximately 256 km of the pipeline passes through the state of Gujarat and approximately 230 km passes through the state of Maharashtra.
The length of spur pipeline to Hazira Manufacturing Division is about 46 km.
The entire DNEPL system will consist of a main 12-inch pipeline from Dahej to Nagothane while the 46 km spur pipeline to Hazira will have a diameter of eight inches, one Mainline Pump Station (PS) at Dhaej, 33 Mainline Block Valves (MLV), two Intermediate Pigging Stations (IPS), two Metering and Regulating (M&R) stations.
The pipeline will be buried throughout its length except at intermediate locations.
The proposed pipeline will be laid in common RoU for a length of about 304 km of the existing East West Gas Pipeline (EWPL) and about 80.5 km of the existing Hazira Dahej Gas Pipeline.

Reliance Gas Pipelines Limited (RGPL) Part-III: Feedstock will help drive plant expansions
The pipeline will help serve the expansions that RIL is putting together for its units in Nagathane and Hazira. The following are the details:
8The Nagothane manufacturing division is located near Raigad, Maharashtra. It comprises of an ethane and propane gas cracker and five downstream plants for the manufacture of polymers, fibre intermediates and chemicals.
8The unit is currently planning expansion of its production capacities by way of de - bottlenecking of various plants. This debottlenecking exercise will involve the GC, EO/EG, LLDPE / HDPE and Hexene-1 plants along with expansion and change of fuel in captive power plant.
8The Hazira manufacturing division is located in Surat, Gujarat. Thecomplex comprises of a naphtha cracker that feeds downstream petrochemical, fibre intermediates and polyester plants.
8The facility is currently undergoing debottlenecking and expansion to increase the production capacities of its plants which includes the cracker and the polyester plants along with other petrochemical plants.

Reliance Gas Pipelines Limited (RGPL) Part- IV: Power requirement details
The power requirement for the electrical equipment will be met through DG sets.
8During construction phase:
-- Entire pipeline will be constructed in six spreads with each spread consuming 15 kVA.
-- Thirty three remote main line valves (MLVs) and two intermediate pigging stations (IPS) will require 50 kVA (portable) per station.
-- Metering and regulating station (M&R) has energy requirement of 50 kVA each at HMD and NMD.
-- Two pump station at DMD will require two 50 kVA sets
8During operation phase:
-- Pump Station's energy requirement of 3750 kVA to be sourced from RIL�s DMD Plant.
-- Thirty three MLVs and two IPSs power requirement will be 100 kVA per station at 2 locations, which will be met with grid power and the other half through solar power in the remaining locations.
-- Metering and Regulating (M&Rs) Stations will require power input of 1.6 MVA at the HMD Plant and 125 kVA at the NMD Plant which will be provided by RIL�s manufacturing division.
