First U.S. Plant to Make Gasoline and Diesel Fuel from Natural Gas
by Peter Spitz Chenected, November 2011
There is an interesting question regarding the contribution that so-called “synthetic fuels” (i.e., those made from raw materials other than crude oil) could make to our motor fuels supply. Technology for several of these fuels has been commercialized, with substantial contributions from chemical engineers. However, the cost of making these and the capital cost for their production facilities is relatively high. So, they only make sense if the price of crude oil price projected to stay high, or if governments are willing to subsidize their production in the national interest.
Almost all automobiles, trucks, ships and some railroads run on liquid fuels derived from crude oil. There has long been a concern that, at some point, global crude oil supply and production will not meet demand, as “peak” oil production is reached. Meanwhile, prices have been on a steady rising trend, reflecting rapidly growing demand for motor fuels in China, India, and elsewhere. When demand exceeds supply on a long-term basis, crude prices will rise rapidly.
So, can we produce these fuels economically from other sources that are relatively much cheaper and broadly available in many parts of the world, specifically, coal or natural gas?
This is an area of considerable interest, but also one with big questions, including believable supply-demand projections, price forecasts, technology, and the willingness to invest very large amounts of capital, as required for plants making these synthetic fuels.
In September of this year SASOL, a South African company, announced its intention to build a 96,000-barrel-per-day gas-to-liquids plant in Lake Charles, LA, based on its Fischer Tropsch process. This technology, first developed in Germany during World War II to make gasoline from coal via production of synthesis gas (CO and hydrogen), can also be used to convert natural gas into gasoline and diesel fuel. The SASOL plant is estimated to cost $ 10 billion(!). The decision to build this plant was evidently based on the large and growing quantities of inexpensive natural gas now being produced from U.S. shale deposits.
A plant of this kind, partly based on SASOL technology, was built by Shell in Qatar and is in successful operation. See photos.
