  • Publication number: 20070167533
    Abstract: A method for alkyl oxygenate (e.g., methanol) manufacture via partial oxidation of alkane (methane) uses an injectively-mixed backmixing reaction chamber in fluid communication with a tubular-flow reactor. Alkyl free radicals are induced in the backmixing reaction chamber prior to being fed through a flow-restriction baffle to the tubular-flow reactor. Injective intermixing of feed streams agitates the backmixing reaction chamber. In one embodiment, a variable position flow restriction baffle is axially moved to commensurately modify the backmixing reaction chamber and tubular-flow reactor volumes. In another embodiment, the tubular-flow reactor is quenched with a variable position quenching input. The method further provides for condensing the output stream from the reaction system in a condensing scrubber and also for recycling a portion of the scrubbed output stream to the reactor system.

  • Publication number: 20070100005
    Abstract: An apparatus and method of producing methanol includes reacting a heated hydrocarbon-containing gas and an oxygen-containing gas in a reactor; to provide a product stream comprising methanol; and transferring heat from the product stream to the hydrocarbon-containing gas to heat the hydrocarbon containing gas. After removing methanol and CO2 from the product stream, unprocessed hydrocarbons are mixed with the hydrocarbon containing gas for reprocessing through the reactor. Reactor byproducts are injected into the ground to increase the output of a hydrocarbon producing well.

  • Publication number: 20060223892
    Abstract: An apparatus and method of producing methanol is provided that reacts a methane-containing gas and an oxygen-containing gas in a reactor to provide a product stream comprising methanol and formaldehyde. The product stream is scrubbed using a process component absorbent. After scrubbing the product stream, unprocessed methane gas is mixed with the methane-containing gas for reprocessing through the reactor while methanol and formaldehyde is sent to a rectification process for removal.

  • Publication number: 20060122283
    Abstract: An apparatus and method of producing methanol includes reacting a heated hydrocarbon-containing gas and an oxygen-containing gas in a reactor; and adding a relatively cold hydrocarbon-containing gas, to be mixed directly with a mixture of the heated hydrocarbon-containing gas and the oxygen-containing gas, after formaldehyde is formed to inhibit decomposition of formaldehyde in the reactor, to provide a product stream comprising methanol and formaldehyde; and transferring heat from the product stream to the hydrocarbon-containing gas to heat the hydrocarbon containing gas.
