    摘要： A process is provided for continuously controlling the hydrocarbon heat content and flow rate of a partial oxidation unit feed-gas stream under conditions where the composition and hence the hydrocarbon heat content of the feed-gas stream is subject to variation. The hydrocarbon heat content of the incoming gases is continuously measured and compared against a design hydrocarbon heat content. An evaluating means calculates whether a moderator is required to decrease the hydrocarbon heat content to the design hydrocarbon heat content or a supplemental high hydrocarbon heat content gas is required to increase the hydrocarbon heat content to the design hydrocarbon heat content. The process utilizes recycle synthesis gas as a moderator. Once the determination is made, the process automatically adjusts flow rates of the recycle synthesis gas stream, the supplemental high hydrocarbon heat content gas stream and the incoming feed-gas stream to provide a partial oxidation unit feed-gas stream with a constant optimum hydrocarbon heat content and flow rate.

    摘要： An improved method for the production of stoichiometric ratioed syngas comprises partially oxidizing a gaseous feedstock containing substantial amounts of methane in a gasifier to produce a hot synthesis gas stream that is passed in indirect heat exchange through a steam reforming catalytic reactor. A portion of the steam reforming reaction products are mixed with the cooled gasifier synthesis gas stream exiting the steam reforming catalytic reactor to form a combined synthesis gas stream, called a "stoichiometric ratioed synthesis gas." The stoichiometric ratioed synthesis gas stream can then be passed into a methanol synthesis unit at substantially the specifications for optimal methanol production with little or no external compression. In a second embodiment the gasifier unit is arranged and operated in parallel with a primary steam reformer unit. The respective synthesis gas streams exiting each unit are combined to form a combined synthesis gas stream that undergoes oxidation in a secondary catalytic reformer unit to form a stoichiometric ratioed synthesis gas that requires minimal external compression before being converted to methanol.
