Utilization of By-product Gas from Steel Plant

PSA pure H₂ technology from coke-oven gas: purity of product H₂ ≥ 99%

The converter gas purification technology: the total sulfur content, total phosphor content, total arsenic content and total fluorine content (volume fraction) in converter gas after purification are less than 1×10^-6 separately.

Rich N₂ purification technology from air separation: N₂ after purification is equal to or more than 99.99%, among which O₂ content (volume fraction) is less than 1×10^-6 separately.

Methanol synthesis technology from the purified gas of the converter gas and H₂ from coke-oven gas by PSA.

Ammonia synthesis technology from rich N₂ of air separation and H₂ from coke-oven gas by PSA.
