  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 ...

  3. Process flow diagram - Wikipedia

    en.wikipedia.org/wiki/Process_flow_diagram

    A process flow diagram (PFD) is a diagram commonly used in chemical and process engineering to indicate the general flow of plant processes and equipment. The PFD displays the relationship between major equipment of a plant facility and does not show minor details such as piping details and designations.

  4. Steam reforming - Wikipedia

    en.wikipedia.org/wiki/Steam_reforming

    Illustrating inputs and outputs of steam reforming of natural gas, a process to produce hydrogen and CO 2 greenhouse gas that may be captured with CCS. Steam reforming or steam methane reforming (SMR) is a method for producing syngas (hydrogen and carbon monoxide) by reaction of hydrocarbons with water. Commonly natural gas is the feedstock.

  5. Hydrogen economy - Wikipedia

    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 ...

    A simple flowchart representing a process for dealing with a non-functioning lamp.. A flowchart is a type of diagram that represents a workflow or process.A flowchart can also be defined as a diagrammatic representation of an algorithm, a step-by-step approach to solving a task.

  8. 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.

  9. Cascade filling system - Wikipedia

    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 ...
