Liquefied Natural Gas
Main Product
Liquefied natural gas (LNG) is the main product produced by Brunei LNG.

Natural gas is mostly supplied by Brunei Shell Petroleum (BSP) which operate three major offshore fields. The largest is South-West Ampa field, about 10 kilometres off Kuala Belait. The other producing fields are Fairley and Gannet. In 1999, natural gas is also supplied to Brunei LNG by Total (a BBJV company) from Jamalul Alam and Maharaja Lela fields. As of August 2003, BSP has a new gas field ( Egret) producing to Brunei LNG.

Liquefied Natural Gas Manufacturing Process:
The Brunei LNG plant was commissioned in 1973 and is located at the coast of Brunei near Lumut, about 80 km from the capital Bandar Seri Begawan.

The natural gas feed to Brunei LNG is supplied by BSP from four major offshore fields. Together with the gas supply from BBJV, the fields deliver more than 25 million m³ of gas a day, which is delivered to Brunei LNG for domestic use and LNG export.
There are five liquefaction trains, each capable of processing 9700 m³ of gas per day. This gives an annual plant capacity of around 7.2 million tonnes of Liquefied Natural Gas (LNG). The LNG is stored in specially designed tanks prior to shipping by dedicated tankers to the customers in Japan and Korea.
Part of the feed is conditioned and exported to the Department of Electrical Services (DES) power plants located in Lumut and near the state capital, Bandar Seri Begawan.

Liquefied Petroleum Gases (LPG) is produced as a by-product. The LPG is used in the LNG process and is bottled in the Bottling plant for domestic sales by BSM.
High temperature steam for the main refrigerant compressor drives and the 4 turbine generators is raised in 9 gas fired boilers and 7 waste heat boilers, which are installed behind the gas turbine generators in the adjacent DES power plant. Additionally there are 3 heat Recovery Steam Generators that are installed behind the HHP gas compressor on Onshore Compression Plant (OCP). An open cooling water system in which 135,000 m³/hr of water is being circulated, is used for heat extraction from the refrigeration and steam cycles. Approximately 2,000 tonnes of water per hour is taken from the Badas river via three 16 km pipelines and chemically treated prior to cooling of equipment and condensate make-up.
The 130-hectare Brunei LNG plant was designed to service the project's original 20-year supply commitment.

In 1993,  Brunei LNG completed a comprehensive rejuvenation of its facilities, invested in 2 new LNG storage tanks, a new jetty extension and secured a new 20 year contract with the Japanese customers.

In 1999, an LNG storage tank was upgraded which increased the LNG storage capacity.

In 2002, the OCP was commissioned. This is an asset of BSP but maintain and operated by Brunei LNG. The plant consists of 3 frame 5-gas compressor and 3 Heat Recovery Steam Generators.
