INTRODUCTION

Reformer tubes normally used in the refining, petrochemical and fertilizer industries are manufactured by the centrifugal casting process and heat-resistant austenitic alloys such as HK -40, HP-40, and HP -Niobium modified materials. A design life of 100,000 operating hours has been the normal time-based criteria for considering retirement of tubes.

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.

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.
