    摘要: The present invention pertains to a method for processing gas containing methane and higher hydrocarbons, comprising the steps of
    • partially condensing and expanding a gas containing methane and higher hydrocarbons from a pressure of 70-120 bar to a pressure of 20-35 bar to obtain at least a C 1 fraction and a C 2 + fraction,
    • separating the C 2 + fraction from the C 1 fraction,
    • separating the C 1 fraction into a first fraction which is brought to a pressure of 20-40 bar and a second fraction which is brought to a pressure of 50-70 bar.
    The C 1 fraction brought to a pressure of 20-40 bar can be subjected to a steam methane reforming process. The C 1 fraction brought to a pressure of 50-70 bar can be subjected to a partial oxidation step. It is preferred for the gas containing methane and higher hydrocarbons to be a natural gas.

    摘要: Provided is a method of producing gas hydrate at a low cost. An acid gas 3 is removed from a natural gas 1, and after dehydration 5 of accompanying water, part of heavy components 7 which do not produce gas hydrate 10 are separated and removed under a relatively high temperature. Moreover, the rest of the heavy components are taken out in a gas hydrate production step 9 together with an excessive portion of light components not contributing to production of the gas hydrate 10, as a fuel gas 11 which is used as a cooling source or a power source for a cooling system in the gas hydrate production step 9.
