H2 Generation from Natural Gas Steam Reforming

For many years in China, H2 generation from natural gas is used to the process of gas preparation for producing synthesis ammonia, which is a long and complicated process with severe operating condition, higher investment and operation cost. Facing such a situation, our company has made an effective innovation in the reformer, desulfurization and conversion, the heat recovering system, etc. On the basis of the original ammonia process of gas preparation. This has made the cost of investment decrease drastically and the consumption of natural gas drop one-third in comparison with the old process. Our company has already transferred the new technology to the units of Pakistan, Bangladesh, Burma and Xinjiang Tianye, Xinjiang Huatai, Xinjiang Zhongtai, Tang Yin County Yuxin Company in Henan Province.

Process flow brief description
The natural gas, prior to pressurization, desulfurization and mixing with aqueous vapor, is passed through a special reformer which is packed with catalyst for cracking and reforming to form the reforming effluent-a mixture of H2, CO2 and CO. After part heat is recovered, hydrogen will be obtained by converting the reforming effluent to reduce the amount of CO content and the shift gas is purified through PSA to ger the pure H2.

Technical features
It is a mature production technology, which can be operated safely and reliably.
Operation and control are reliable and applicable, and the automation is high.
The operation cost is low and the investment will be recovered in a short period of time.
The desorbed gas from PSA can be burned; Which can both reduce the fuel consumption and decrease the ventilation of the waste gas.
