  2. Hydrogen production - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_production

    In this process, hydrogen is produced from a chemical reaction between steam and methane, the main component of natural gas. Producing one tonne of hydrogen through this process emits 6.6–9.3 tonnes of carbon dioxide. [4] When carbon capture and storage is used to remove a large fraction of these emissions, the product is known as blue ...

    en.wikipedia.org/wiki/Modeling_and_simulation_of...

    Process simulation describes processes flow diagram where various unit operations are present and connected by product streams. It is extensively used both in educational arena and industry to predicate the behavior of a process using material balance equations, equilibrium relationship, reaction kinetics, etc. [ 6 ]

  4. BMA process - Wikipedia

    en.wikipedia.org/wiki/BMA_process

    The BMA process or Degussa process is a chemical process developed by the German chemical company Degussa [1] for the production of hydrogen cyanide from methane and ammonia in presence of a platinum catalyst.

    In this process, hydrogen is produced from a chemical reaction between steam and methane, the main component of natural gas. Producing one tonne of hydrogen through this process emits 6.6–9.3 tonnes of carbon dioxide. [40] When carbon capture and storage is used to remove a large fraction of these emissions, the product is known as blue ...

    en.wikipedia.org/wiki/Cascade_filling_system

    Hydrogen storage cylinders in a cascade filling system A cascade filling system is a high-pressure gas cylinder storage system that is used for the refilling of smaller compressed gas cylinders. [ 1 ] [ 2 ] In some applications, each of the large cylinders is filled by a compressor , otherwise they may be filled remotely and replaced when the ...

  7. Hazard and operability study - Wikipedia

    en.wikipedia.org/wiki/Hazard_and_operability_study

    For process plants, identifiable sections (nodes) are chosen so that for each a meaningful design intent can be specified [citation needed]. They are commonly indicated on piping and instrumentation diagrams (P&IDs) and process flow diagrams (PFDs). P&IDs in particular are the foremost reference document for conducting a HAZOP.

    In Klein’s case, a Postal Service spokeswoman said, the problem is the road. Hillman Ridge is paved but narrows to a width slightly larger than a pickup truck as it approaches Klein’s property.

  9. Thermochemical cycle - Wikipedia

    en.wikipedia.org/wiki/Thermochemical_cycle

    In chemistry, thermochemical cycles combine solely heat sources (thermo) with chemical reactions to split water into its hydrogen and oxygen components. [1] The term cycle is used because aside of water, hydrogen and oxygen, the chemical compounds used in these processes are continuously recycled.
