文摘

NGH production from methane steam reforming and CO2/H2 replacement was proposed. H2 is to decrease the partial pressure of methane and break methane hydrate stability. Higher H2 ratio in feed gas results in higher accumulative gas production ratio but lower CO2 SR. Gas replacement by CO2/H2 mixture improves gas production ratio and rate.
