Objectives
Petrochemical project of GAIL (India) Ltd. is a large scale integrated grass-root petrochemical plant located at Pata, near Auraiya district in UP on Kanpur-Agra national highway. The plant processes natural gas to produce major petrochemical products such as LPG, Propane, HDPE & LLDPE.
The objectives of the proposed study at GAIL (India) Ltd., Pata, UP are:

• To conduct energy audit on all the important systems & major energy guzzlers so as to identify potential areas where energy can be saved in any form with or without investment.
• To prioritize the potential energy saving areas depending upon envisaged savings, investment cost, time for execution, and payback period etc.
• To carry out the feasibility study of installing VSD’s in fans/compressor/pumps etc.

Activities
The energy audit has covered the energy intensive systems/equipment installed in the plants, viz. gas sweetening unit (GSU), gas processing unit (GPU), gas cracker (GCU), LPG, HDPE, LLDPE & Butene-1, as listed below:

• Electrical System Network
• Transformers
• Power Factor and Demand Management
• Motive Loads
• Air & Nitrogen compressors
• DG Sets
• Lighting System
• Utility Boilers
• Steam Distribution Network
• Waste Heat Recovery Boilers
• Condensate Recovery
• Furnace/Ovens
• Steam Turbine & Driven Machines
• Gas Turbine driven compressor in GPU
• Water pumping systems and cooling towers

Project Status
WII has commenced the energy audit at GAIL Pata, U.P. on 4th of December 2006. Field measurements were carried out in two phases (December 2006 and February 2007) along with PCRA energy auditors.  The draft energy audit report was prepared and submitted to PCRA in March 2007.  WII has assisted PCRA in presenting the recommendations of the energy audit to GAIL Management in March 2007.  The final report is being prepared based on the suggestions / comments received from GAIL.  The final report will be submitted to PCRA in May 2007.
