Introduction
Badak LNG plant consists of 8 LNG Trains having a total production capacity of 22.5 mtpa LNG and 1.0 mtpa LPG. The feed gas delivered from the existing gas field will be replaced gradually by another source i.e.: deep water gas and even coal bed methane. The challenge in the Badak LNG Plant now is change of the feed gas compositions. The future new feed gas sources are lean which having methane content of 93 ? 97 %-vol, compare to the current methane content of 83-85 %-vol.
Conclusions
Assessment of the existing plant facilities is required for anticipating the future feed gas composition change. Lean gas will not cause remarkable changes at the gas treating unit. Some modifications or operational changes of the fractionation, liquefaction and refrigerant unit might be required.
