The LNG unloaded by the Shipper must comply with the following specifications:



kWh/Nm3 10.70 12.75
Wobbe Index kWh/Nm3 13.40 15.65
RSH (as S) mg S/Nm3   6
COS+H2S (as S) mg S/Nm3   5
Total S mg/Nm3   30
Hg ng/Nm3   50
O2 ppmv   100
Impurities Gas that can be received without undergoing additional treatment on entering the Terminal

These specifications may change depending on any evolution of the specifications on the network.

Requirements for physical and chemical characteristics

The characteristics of the gas leaving LNG terminal facilities to enter the natural gas pipeline networks must always comply with the latest gas regulations.

The regulatory requirements of 18 October 2004 are:

  • Gross Calorific Value [GCV] (combustion conditions: 0°C and 1.01325 bar) => 10.7 to 12.8 kWh/Nm³ (combustion 25°C: 10.67 to 12.77)  (1)
  • Water dew point below -5°C at maximum network service pressure  (2)

Sulphur and H2S content

Snapshot H2S content must be less than 15 mg/Nm³ (exceeding 12 mg/Nm³ for no more than 8 hours).

Average H2S content over 8 days must be under 7 mg/Nm³.

Total sulphur content must be under 150 mg/ Nm³.

(1) "H type" gas: high GCV gas.

(2) Converting water dew point into water content and vice-versa is carried out in compliance with ISO 18 453 "Natural gas – Correlation between water content and water dew point." (Gergwater correlation).

For further information, please refer to article 12 of the General Terms and Conditions of the LNG Terminal Access Contract.
