RBN Energy: Primer on Gas-to Liquids

Link here.
Sasol Ltd. announced in September 2011 that they have selected a site in southwest Louisiana as a possible location for a multibillion-dollar plant that converts natural gas to diesel and other products. The company will conduct an 18-month feasibility study that weighs the regulatory process, “supply issues,” capital costs and other factors before it decides whether to proceed. If the Sasol plant proceeds as planned, construction is expected to start in 2013, and the complex would be built in two phases that upon completion in 2018 would process approximately 4 million tons of products per year, with a maximum capacity of 96,000 barrels per day.
In early April 2012 the Wall Street Journal reported that Royal Dutch Shell PLC is also considering building a giant plant in Louisiana to convert natural gas to diesel. The plant, which could cost more than $10 billion, would be similar in size to Shell's Pearl gas-to-liquids facility in Qatar. The Pearl GTL plant is the world’s largest and made its first commercial shipment in June 2011. The Pearl plant is expected to reach full capacity in 2012 – converting 1.6 BCF a day of natural gas into 140,000 barrels of petroleum products (primarily naphtha).
