Carbon2Chem® pilot plant station in Duisburg.

The technical implementation of the concept is tested under real conditions in the Carbon2Chem® pilot plant station. It offers 3700 m2 of space and is directly next to the thyssenkrupp Steel Europe AG premises in Duisburg.

Analytics

  • Laboratory 5 is a high-tech analysis laboratory to analyze the gases from gas processing before they are converted into raw materials by the project partners in other laboratories. The gas composition is determined down the smallest detail by a PTR-QiTOF-MS (Proton Transfer Reaction-Quadrupole interface-Time of Flight-Mass Spectrometer) and by two micro GCs.


    Aim

    Continuous online measurement of the purified gases and identification of all main (% range), secondary (‰ to ppm range), and trace compounds (ppb to ppt level)

    • Identification of potential catalyst poisons at a ppb or ppt level
    • Quantification and monitoring of the time profiles of any critical components that may be present


    Application

    • Chromatographic determination of main and secondary components
    • Characterization of the trace components with three different primary ions (H3O+, NO+, and O2+)
    • Permanent monitoring of the purified gases to prevent any catalyst deactivation
    • Calibration of relevant substances
    • Long-term measurement campaigns to support the optimization of gas treatment
    • Parameter optimization (dilution factor, collision energy, pressure, temperature, etc.)


    Technical specification

    • Online gas chromatography via two micro GCs
    • Online trace analysis
    • A mobile analysis system with installed dilution apparatus (up to 1:1000 with N2)
    • Specially developed monitoring system to monitor critical components in real time
  • The HüGaProp (Hüttengas-Properties, metallurgical gas properties) containers are two containers, one of which is a laboratory container and the other a supply container. The trace components in the three raw metallurgical gases (coke oven gas, blast furnace gas, and basic oxygen furnace gas) are characterized in the laboratory container, whereas the supply container provides the gas supply to the analysis equipment. The main components are determined using a GC with FID/WLD, while the trace compounds are measured with a PTR-TOF-MS.
