Utilization of By-product Gas from Steel Plant
   1. PSA- pure H2 technology from coke-oven gas: purity of product H2 ≥ 99%

    2. 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.

    3. 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 .

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

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