  2. Process engineering - Wikipedia

    en.wikipedia.org/wiki/Process_engineering

    Process engineering is the understanding and application of the fundamental principles and laws of nature that allow humans to transform raw material and energy into products that are useful to society, at an industrial level. [1] By taking advantage of the driving forces of nature such as pressure, temperature and concentration gradients, as ...

  3. Process design - Wikipedia

    en.wikipedia.org/wiki/Process_design

    Process design can be the design of new facilities or it can be the modification or expansion of existing facilities. The design starts at a conceptual level and ultimately ends in the form of fabrication and construction plans. Process design is distinct from equipment design, which is closer in spirit to the design of unit operations.

  4. Semiconductor device fabrication - Wikipedia

    en.wikipedia.org/wiki/Semiconductor_device...

    Semiconductor equipment may have several chambers which process wafers in processes such as deposition and etching. Many pieces of equipment handle wafers between these chambers in an internal nitrogen or vacuum environment to improve process control. [3]

  5. Industrial process control - Wikipedia

    en.wikipedia.org/wiki/Industrial_process_control

    Industrial process control (IPC) or simply process control is a system used in modern manufacturing which uses the principles of control theory and physical industrial control systems to monitor, control and optimize continuous industrial production processes using control algorithms. This ensures that the industrial machines run smoothly and ...

  6. Mixing (process engineering) - Wikipedia

    en.wikipedia.org/wiki/Mixing_(process_engineering)

    Mixing of liquids occurs frequently in process engineering. The nature of liquids to blend determines the equipment used. Single-phase blending tends to involve low-shear, high-flow mixers to cause liquid engulfment, while multi-phase mixing generally requires the use of high-shear, low-flow mixers to create droplets of one liquid in laminar, turbulent or transitional flow regimes, depending ...

  7. Industrial control system - Wikipedia

    en.wikipedia.org/wiki/Industrial_control_system

    Industrial control system. An industrial control system (ICS) is an electronic control system and associated instrumentation used for industrial process control. Control systems can range in size from a few modular panel-mounted controllers to large interconnected and interactive distributed control systems (DCSs) with many thousands of field ...

  8. Piping and instrumentation diagram - Wikipedia

    en.wikipedia.org/wiki/Piping_and_instrumentation...

    A piping and instrumentation diagram (P&ID) is defined as follows: A diagram which shows the interconnection of process equipment and the instrumentation used to control the process. In the process industry, a standard set of symbols is used to prepare drawings of processes. The instrument symbols used in these drawings are generally based on ...

  9. 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. Another commonly used term for a PFD is ...
