Define Utility, Auxillary And Process Flashcards
Auxiliary
systems that are not directly involved in a process but that support it and are vital to its operation
Process systems
systems that are directly involved in making chemical and/or physical changes in materials to produce an intermediate or final product (such as chemical reactors and separation processes like distillation
Utility systems
systems that provide basic services to a plant such as energy (electricity, fuel, and steam), gases (nitrogen, air, and fuel gas), and water (cooling water, potable water, and water/wastewater treatment),
Control diagram
is similar to a process flow diagram, but it typically has abbreviated control loops. Control diagrams shown on screens in control rooms will typically display current process variables
