  • Patent number: 6541524
    Abstract: Facilities to convert natural gas into syncrude often are located at remote sites. At these sites and in their surrounding communities there exists demand for salable products: gasoline, distillate fuels, solvents, lubricants, etc. While it would be possible to produce these products from syncrude, the construction of such production facilities would be very expensive, and their operation would be difficult at the remote site. Fischer-Tropsch syncrude will be waxy and will also contain volatile components, complicating the shipping of both Fischer-Tropsch products from remote production sites to developed sites and salable products from developed sites to remote sites. This invention describes a safe process to both transport Fischer-Tropsch syncrude from the remote site to the developed site and supply salable products from the developed site to the remote site.
