Brief Summary of Proposed Project

INTRODUCTION GAIL () Limited (‘GAIL’) along with Hindustan Corporation Limited (‘HPCL’) is exploring the opportunity for setting up a Greenfield Complex in Andhra Pradesh to produce 1 MMTPA of ethylene and ethylene derivatives based on imported ethane and / or Naphtha available in domestic market. Project Location The proposed Petrochemical complex will be located at A.V. Nagaram village, Thondangi Mandal of East Godavari district, Andhra Pradesh. The proposed complex is spread across 2000 acres. Nearest airport is (87 km) from proposed site. Power source 33KV /132 KV Power source from AP Transmission Corporation at Pithapuram substation is available near the site at a distance of about 25 Km. Construction and Permanent water source Site has proximity with the source of water. Polavarum left main Canal (AP irrigation) is approximately 12 KM from the proposed site, Samalkot is an alternate source of water which is around 28 KM from the proposed site. Environmental requirements No Ecologically sensitive area like national monument / bird sanctuaries/ major settlement is located within 25 Km of site. Defence requirements No Defence base within 25 Km of the site. Downstream Industry No downstream industry related to Petrochemical in the vicinity. Topography of site & development requirement: The topography of the proposed area is flat terrain with minor sand dune hillocks which includes one major Creek running across the proposed site.

Utilities Description Facilities in utility systems are enlisted below:

 Cooling water system  Steam, Power and boiler feed water system  Treated Raw water system  DM Water plant  Condensate polishing system  N2O2 (Nitrogen/Oxygen) Plant  Instrument Air & Plant Air system  Effluent treatment Plant   Flare system Cooling Water Requirement for the Complex is about 125000 M3/Hr. To carter to the requirement cooling towers with cell capacity of 4000 M3/Hr each. In order to meet the steam, power and boiler feed water demands of the facilities installed at the Petrochemical complex, dedicated steam, power and BFW system will be installed as part of the Captive Power Plant (CPP). Raw Water Requirement Raw Water requirement is 3900 m3/hr. Water will be sourced from Polavaram Canal which is 12 kms from the Complex. Raw water shall be made available at complex battery limit from canal via Raw Water Pumping facility. To meet the complex demand one raw water reservoir of 2100000 m3 capacities is considered. This reservoir is designed to cater the 21 days of raw water demand. DM Water/Oxygen/Instrument & Plant Air Requirement

The normal requirement of DM water is about 210 M3/Hr of DM water and 590 M3/Hr of net raw water generation. The requirement of Oxygen is 1450 TPD (Design) and that of Nitrogen is Normal – 12776 NM3/Hr and Max – 20000 NM3/Hr. Oxygen is required in MEG unit as a raw material.

The design requirement of Instrument air and plant air is about 6000 NM3/Hr and 5500 NM3/Hr respectively.

Effluent Treatment Plant

The Effluent treatment plant is shall take care the following effluent quantity.

 Oily Effluent 250 M3/Hr.

2

 Wet air oxidation unit to treat spent Caustic of about 2 M3/Hr

Various Effluents generated from the complex shall be treated in a centralized ETP. The various effluents sent to the ETP broadly consist of the following:

 Oily Water Sewerage  Contaminated Rain Water Sewerage  Spent Caustic Stream  Sanitary Effluent

Flare System A centralized demountable flare system is proposed for the facility. A Demountable flare system provides flexible flaring operations to so that you can place multiple risers on a single support structure. They also allow you to perform maintenance to the tip at grade with minimal use of personnel at elevation.

3 Risers are presently envisaged in the flare:

 Flare gas from Cracker  Flare gas from polymer units  Flare gas from storage facilities

Offsite Description

Offsite facilities will include storage vessels / tanks / sphere for feed, intermediates feed, Off spec intermediate feed & products, pumping facilities, loading / unloading facilities and auxiliary facilities like boil off gas compression system, emergency vaporization / heating system / vapor recovery system etc. Offsite storage summary is given in Table 2.
