obtained in the catalytic oxidation process for the generation of synthesis gas and or the fischer tropsch reaction for the liquefaction of natural gas both processes are highly exothermic and usually the excess heat is removed by steam cooling the steam thus generated may be used for the production of power to be used in the liquefaction process part of the energy may also be used in the hydrocarbon synthesis plant but certainly the excess may be used in the liquefaction process in the case that only a limited amount of end flash gas would be available the preference is given to use it in the manufacturing steam methane reforming of hydrogen and or synthesis gas having a high hydrogen carbon monoxide ratio it is preferred to use the end flash gas first as feed for the steam methane reforming process and when sufficient gas is available also as fuel for the process usually to replace off gas from the hydrocarbon synthesis reaction when more end flash gas is available or in the case that it is not desired to use it as fuel for the steam methane reforming process this can be used in the preparation of synthesis gas for the hydrocarbon synthesis reaction for a liquefaction plant designed to produce 4 mpta lng the amount of end flash gas could be between 0 4 and 1 2 mpta such an amount of end flash gas may result in an increase of lng production.
