<p>This invention comprises a method for converting natural gas to a normally liquid carbon containing compound, such as methanol and/or dimethyl ether and/or to gasoline grade liquid hydrocarbons and/or olefins. The method of this invention elininates the need for steam reforming and/or adiabatic reforming with essentially pure oxygen of the natural gas to a synthesis gas. In accordance with the process of this invention, a synthesis gas may be produced at an op- erating pressure suitable for conversion thereof to methanol and/or dimethyl ether without the need for synthesis gas recompression. Fur- ther, the vent or bleed gas from the overheads after conversion to the crude product methanol/DME and/or its conversion to gasoline grade liquid hydrocarbons, generally has a BTU capacity required to serve as a fuel gas for supplying the energy needed for operation of the gas compression equipment requirements by which the process of this invention may be practiced. Accordingly, the capital and operat- ing cost associated with the production of methanol, DME and gaso- line from natural gas is significantly reduced by the method of this in- vention and renders it economically feasible for natural gas recovery processing at remote locations.</p> |
