  • Patent number: 4782096
    Abstract: A process for producing an organic compound from a hydrocarbon containing feedstock. The feedstock is divided into two fractions. The first is subject to a primary steam reforming reaction. The reaction product is then combined with the second fraction and reacted with a free oxygen-rich gas in a secondary reforming reactor to form a synthesis gas having a ratio ofH.sub.2 /[2(CO)+3(CO.sub.2)]between 0.80 and 1.00. The synthesis gas is then mixed with a hydrogen-rich stream, which has been separated from a purge gas from the synthesis loop, to form a final synthesis gas. The final synthesis gas is injected into a synthesis loop in which the desired organic compound is formed. The purge gas extracted from the loop is subjected to a physical separation to form a hydrogen-rich gas stream and a residual gas stream. A portion of the hydrogen-rich stream is recycled to form the final synthesis gas.

  • Patent number: 4524056
    Abstract: A process for the production of ammonia, comprising the steps of: (a) gasifying a feedstock containing carbon and a source of hydrogen with air as the only source of free oxygen, to produce a raw synthesis gas comprising nitrogen, hydrogen, carbon oxides, and methane; (b) subjecting the raw synthesis gas to a shift conversion reaction; (c) removing the carbon oxides from the shift converted raw synthesis gas to produce a purified synthesis gas; (d) mixing the purified synthesis gas with a hydrogen-rich gas to form a final synthesis gas; (e) injecting the final synthesis gas into an ammonia synthesis loop to produce ammonia and a purge gas; (f) separating the purge gas cryogenically, to produce a methane-rich gas, a nitrogen-rich gas, and the hydrogen-rich gas; and (g) recycling the hydrogen-rich gas to step (d). The methane-rich stream is at least partially recycled to step (a). Sulfur compounds, if necessary, may be removed from the raw synthesis gas.
