  2. 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.

  3. Piping and instrumentation diagram - Wikipedia

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

    P&IDs are originally drawn up at the design stage from a combination of process flow sheet data, the mechanical process equipment design, and the instrumentation engineering design. During the design stage, the diagram also provides the basis for the development of system control schemes, allowing for further safety and operational ...

    en.wikipedia.org/wiki/Flow_process_chart

    Another 1944 graduate, Ben S. Graham, Director of Formcraft Engineering at Standard Register Corporation, adapted the flow process chart to information processing with his development of the multi-flow process chart to display multiple documents and their relationships. In 1947, ASME adopted a symbol set derived from the Gilbreths' original ...

  5. 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.

  6. Instrumentation in petrochemical industries - Wikipedia

    en.wikipedia.org/wiki/Instrumentation_in...

    Some instrumentation is self actuating. For example, pressure regulators maintain a constant pre-set pressure, and rupture discs and pressure safety valves open at pre-set pressures. [3] Instrumentation includes facilities for operating personnel to intervene in the plant either locally or from a control room.

  7. Flowchart - Wikipedia

    en.wikipedia.org/wiki/Flowchart

    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. Chemical engineering - Wikipedia

    en.wikipedia.org/wiki/Chemical_engineering

    Chemical engineers design, construct, and operate process plants, such as these fractionating columns.. Chemical engineering is an engineering field which deals with the study of the operation and design of chemical plants as well as methods of improving production.
