Objectives and Scope of the Module
The objective of the present Module is to provide a comprehensive and integrated knowledge related to the flowsheet, the basic processes, the production units, the products and the equipment of a modern petroleum refinery.
To that effect, the module contains the description and flowsheet of a refinery, the raw materials, the mass and energy flows, the products and the process details of each unit in the aforementioned flowsheet.
In addition some of the downstream processes (petrochemicals and plastics) are also described in order to provide an integrated view of the whole production chain.
The basic production equipment and its operation is also described in the Molule.
Concerning rotating equipment, maintenance strategies and special predictive methods in order to maximize availability, are also presented.
One site visit is also included in the Module.
Expected Learning Outcomes
The students by the completion of the Module will have a clear idea about the basic flowsheet, the processes, the units and their products as well as about the basic equipment of a modern refinery.
