Method and system for decarburized LNG production

An integrated natural gas liquefaction system, hydrogen production system and power generation system to improve CO2 capture and improve overall plant efficiency. An end flash, predominantly methane, is sent to a hydrogen production system that produces hydrogen and CO2. The CO2 may be captured or advantageously used. At least a portion of the generated hydrogen is used to fuel the gas turbine in power generation, which in turn powers the refrigeration compressor of the natural gas liquefaction system in the form of mechanical work or electric power. 一种集成天然气液化系统、氢生产系统和功率生成系统，以提高CO2捕获和改善整体工厂效率。主要是甲烷的端部闪蒸被送到氢生产系统，该氢生产系统产生氢气和CO2。CO2可以被捕获或有益地使用。所产生的氢气中的至少一部分用于在功率生成中为燃气轮机提供燃料，而该功率生成又以机械功或电力的形式为天然气液化系统的制冷压缩机提供功率。
