NOVELTY - Generating hydrocarbon compounds comprising at least two carbon atoms (C1), comprises: (a) directing natural gas feed stream to at least one separation unit; (b) directing methane separated in (a) to syngas unit, and oxidizing methane to hydrogen and carbon monoxide; (c) directing the hydrogen and carbon monoxide to Fischer-Tropsch unit reacting the hydrogen and carbon monoxide in Fischer-Tropsch process to generate a product stream comprising C1; and (d) directing C1 separated in (a) and product stream generated in (c) to fractionation unit to separate C1 into individual streams.    USE - The method is useful for generating hydrocarbon compounds comprising at least two carbon atoms.    ADVANTAGE - The method: reduces the quantity carbon monoxide and/or carbon dioxide that are directed to the environment, which decrease overall greenhouse emissions; and provides requisite unit operations to convert the methane to higher molecular weight hydrocarbons.    DETAILED DESCRIPTION - Generating hydrocarbon compounds comprising at least two carbon atoms (C1), comprises: (a) directing a natural gas feed stream comprising methane and C1 to at least one separation unit to separate the methane from the C1 compounds, where the natural gas feed stream is from a non Fischer-Tropsch process; (b) directing at least a portion of the methane separated in (a) to a syngas unit, and in the syngas unit partially oxidizing the methane to hydrogen and carbon monoxide; (c) directing the hydrogen and carbon monoxide to a Fischer-Tropsch unit comprising a Fischer-Tropsch catalyst, and in the Fischer-Tropsch unit reacting the hydrogen and carbon monoxide in a Fischer-Tropsch process to generate a product stream comprising C1; and (d) directing the C1 separated in (a) and the product stream comprising the C1 generated in (c) to a fractionation unit, and in the fractionation unit separating the C1 into individual streams. An INDEPENDENT CLAIM is also included for a system for generating hydrocarbon compounds containing C1, comprising at least one separation unit that accepts a natural gas feed stream comprising methane and C1 from a non-Fischer-Tropsch process and separates the methane from the C1, a syngas unit downstream of and fluidically coupled to the at least one separation unit, where the syngas unit accepts at least a portion of the methane separated in the at least one separation unit and partially oxidizes the methane to hydrogen and carbon monoxide, a Fischer-Tropsch unit downstream of and fluidically coupled to the syngas unit, where the Fischer-Tropsch unit comprises a Fischer-Tropsch catalyst for facilitating a Fischer-Tropsch process, and where the Fischer-Tropsch unit accepts the hydrogen and the carbon monoxide and reacts the hydrogen and the carbon monoxide in the Fischer-Tropsch process to generate a product stream comprising C1 and a fractionation unit downstream of and fluidically coupled to the at least one separation unit and the Fischer-Tropsch unit, where the fractionation unit accepts the C1 separated in the at least one separation unit and the product stream comprising the C1 generated in the Fischer-Tropsch unit, and separates the C1 into individual streams.
