There are a number of systems in a large complex processing facility such as a refinery or chemical plant that are classified as “systems”. They cannot be looked at in isolation since they support multiple units within the entire complex. These include Instrumentation and Control; Electric Power; and Utility Systems , e.g., steam, cooling water, instrument air, firewater, flare, tankage; and receipt and shipment, e.g., marine terminalling and truck/rail loading.
