Dahej – Nagothane Ethane Pipeline (DNEPL)

Reliance Gas Pipelines Limited (RGPL), in the process of building a 440 km long pipeline for transportation of liquid Ethane. The pipeline will transport liquid Ethane made available from RIL’s Dahej Manufacturing Division (DMD) to RIL’s Nagothane Manufacturing Division (NMD). The dedicated pipeline, named as Dahej – Nagothane Ethane Pipeline (DNEPL) is designed to transport 1.25 MMTPA of liquid Ethane.

PNGRB has granted acceptance to RGPL’s proposal to lay, build, own and operate DNEPL as dedicated line.

DNEPL System Configuration

The DNEPL project comprises - 12” dia (NB) x 440 km mainline from DMD to NMD, 1 Pump Station (PS) at DMD, 33 Mainline Valve Stations (MLV), 2 Intermediate Pigging Stations (IPS) and 1 Metering and Regulating (M&R) station at NMD, Cathodic protection system, Supervisory Control and Data Acquisition (SCADA) system, dedicated Optical Fibre Cable (OFC) based telecommunication system, provision for flaring at MLVs/IPSs during any emergency, leak detection system / pipeline application software, pipeline intrusion detection system, flow measurement and control instrumentation, fire and gas detection system, fire protection system, control and auxiliary buildings and associated facilities.

The pipeline is designed, engineered and implemented in accordance with OISD 214 (Cross – Country LPG pipelines) and American Society of Mechanical Engineers (ASME) Standard, B31.4 (Pipeline Transportation Systems for Liquid Hydrocarbons and other Liquids).
