  2. 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 ...

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

  4. Piping - Wikipedia

    en.wikipedia.org/wiki/Piping

    Piping. Within industry, piping is a system of pipes used to convey fluids (liquids and gases) from one location to another. The engineering discipline of piping design studies the efficient transport of fluid. [1][2] Industrial process piping (and accompanying in-line components) can be manufactured from wood, fiberglass, glass, steel ...

  5. Front-end engineering - Wikipedia

    en.wikipedia.org/wiki/Front-end_engineering

    Front-End Engineering (FEE), or Front-End Engineering Design (FEED), is an engineering design approach used to control project expenses and thoroughly plan a project before a fix bid quote is submitted. [1] It may also be referred to as Pre-project planning (PPP), front-end loading (FEL), feasibility analysis, or early project planning.

  6. Hazard and operability study - Wikipedia

    en.wikipedia.org/wiki/Hazard_and_operability_study

    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. The extent of each node should be appropriate to the complexity of the system and the magnitude of the hazards it might pose.

  7. Process design - Wikipedia

    en.wikipedia.org/wiki/Process_design

    In chemical engineering, process design is the choice and sequencing of units for desired physical and/or chemical transformation of materials. Process design is central to chemical engineering, and it can be considered to be the summit of that field, bringing together all of the field's components. Process design can be the design of new ...

    en.wikipedia.org/wiki/ISO_10628

    ISO 10628. ISO 10628 Diagrams for the chemical and petrochemical industry specifies the classification, content, and representation of flow diagrams. It does not apply to electrical engineering diagrams. ISO 10628 consists of the following parts: Part 1: Specification of Diagrams (ISO 10628-1:2014) [1] Part 2: Graphical Symbols (ISO 10628-2:2012)

  9. Check valve - Wikipedia

    en.wikipedia.org/wiki/Check_valve

    Tilting-disc inconel check valve Check valve symbol on piping and instrumentation diagrams.The arrow shows the flow direction. Vertical lift check valve. A check valve, non-return valve, reflux valve, retention valve, foot valve, or one-way valve is a valve that normally allows fluid (liquid or gas) to flow through it in only one direction.
