  2. Caffenol - Wikipedia

    en.wikipedia.org/wiki/Caffenol

    Caffenol is a photographic alternative process whereby phenols, sodium carbonate and optionally vitamin C are used in aqueous solution as a film and print photographic developer. [ 1 ] [ 2 ] Other basic (as opposed to acidic ) chemicals can be used in place of sodium carbonate; however, sodium carbonate is the most common.

  3. C-41 process - Wikipedia

    en.wikipedia.org/wiki/C-41_process

    C-41 is a chromogenic color print film developing process introduced by Kodak in 1972, [citation needed] superseding the C-22 process.C-41, also known as CN-16 by Fuji, CNK-4 by Konica, and AP-70 by AGFA, is the most popular film process in use, with most, if not all photofinishing labs devoting at least one machine to this development process.

  5. 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.

  7. Process design - Wikipedia

    en.wikipedia.org/wiki/Process_design

    Process flow diagrams (PFD): Typically more complex diagrams of major unit operations as well as flow lines. They usually include a material balance, and sometimes an energy balance, showing typical or design flowrates, stream compositions, and stream and equipment pressures and temperatures. It is the key document in process design. [1]

  8. Continuous Liquid Interface Production - Wikipedia

    en.wikipedia.org/wiki/Continuous_Liquid...

    The continuous process begins with a pool of liquid photopolymer resin. Part of the pool bottom is transparent to ultraviolet light (the "window"). An ultraviolet light beam shines through the window, illuminating the precise cross-section of the object. The light causes the resin to solidify.

  9. Chemical process modeling - Wikipedia

    en.wikipedia.org/wiki/Chemical_process_modeling

    Chemical process modeling is a computer modeling technique used in chemical engineering process design. It typically involves using purpose-built software to define a system of interconnected components, [ 1 ] which are then solved so that the steady-state or dynamic behavior of the system can be predicted.
