Process and system for converting non-methane hydrocarbons to recover hydrogen and/or methane gas therefrom

The present disclosure relates to methods, systems, and apparatus arranged and designed for converting a non-methane alkane gas into a plurality of product gas streams including a hydrogen-dominated stream and a methane gas vapor-dominated stream. A hydrocarbon gas stream is reformed, cracked or converted into a syngas stream and a methane gas stream by receiving a volume of flare gas or other hydrocarbon liquid or gas feed, where the volume of hydrocarbon feed includes a volume of methane and a volume of non-methane hydrocarbons. The hydrogen contained in the syngas can be separated into a pure hydrogen stream. A corresponding gas conversion system may include a superheater to provide a hydrocarbon feed/steam mixture, a heavy hydrocarbon reactor for syngas formation, and a hydrogen separator to recover the hydrogen portion of the syngas. 本公开涉及被布置和设计用于将非甲烷烃气体转化成包括以氢气为主的流和以甲烷气体蒸汽为主的流的多种产物气体流的方法、系统和装置。通过接收一定体积的火炬气或其他烃液体或气体进料，将烃气体流重整、裂化或转化成合成气流和甲烷气体流，其中该一定体积的烃进料包括一定体积的甲烷和一定体积的非甲烷烃。该合成气中所含的该氢可被分离成纯氢气流。对应气体转化系统可包括
