Natural gas pressure difference energy recovery and electrolytic hydrogen production integrated system

摘要: The invention relates to a natural gas pressure difference energy recovery and electrolytic hydrogen production integrated system. system is arranged between high-pressure trunk line low-pressure comprises device, power generation device an electrolyzing water which are connected in sequence. Accordingly, firstly, normal-temperature subjected preheating expansion depressurization through first expander unite of the sequence form gas; then, mechanical work output by unit converted into device; finally, used for produce high-purity sufficient can be achieved, then prepare purity reaches up 99.99%; meanwhile, also prepared pipe network.
