Description
Natural Gas Steam Reforming for Syngas Production Process Description:
Natural gas is compressed to 3.5 MPa, finely desulfurized to ≤0.1 ppm, and mixed with process steam at a molar ratio of 3.5 times. It then enters the steam reforming furnace, where methane is reformed at 800–900°C and 2–3 MPa over a nickel catalyst, achieving a methane conversion rate ≥95%. Syngas with an H₂/CO ratio of approximately 3.0 is produced, with energy consumption ≤27 GJ per ton of ammonia.
Syngas to Hydrogen Process Description:
Syngas undergoes medium-temperature shift to convert CO into H₂ and CO₂, followed by pressure swing adsorption (PSA) purification to obtain hydrogen with purity ≥99.99% and a recovery rate ≥85%. The desorption gas is returned to the reforming furnace as fuel, and the hydrogen is supplied externally to hydrogen refueling stations or refining units.
Syngas to Synthetic Ammonia Process Description:
Purified syngas is mixed with nitrogen from air separation at an H₂/N₂ ratio of 3.0, compressed to 14–16 MPa, and fed into a radial ammonia synthesis tower. Ammonia is synthesized over an iron-based catalyst at 400–450°C, with a single-pass conversion rate ≥18%. Liquid ammonia is obtained after freezing separation.
Syngas to Methanol Process Description:
Syngas is compressed to 5–8 MPa and synthesized into crude methanol over a copper-based catalyst at 220–260°C. The reaction heat produces 2.5 MPa steam as a by-product. AA-grade refined methanol is obtained through three-tower distillation, with comprehensive energy consumption ≤28 GJ per ton of methanol and catalyst life ≥3 years.
Manufacturing, Installation, and Commissioning Period:
Utilizing modular design, core equipment such as reforming furnaces and synthesis towers are prefabricated in the factory and assembled on-site. The total project duration from contract signing to successful commissioning is 10–12 months.
