HEN Retrofit Solution in an AVCODU by Using Process
Heat Integration and Process Simulation Methodologies

Abstract:

The recent energy and environmental issues urge the need to revamp the existing plants in order to minimize the energy requirements and consequently decreases environmental pollution. This paper represents an application of methods for performance analysis of existing processes and finding of retrofit solutions through the application of techniques for process modeling and simulation and process integration. An in atmospheric and in vacuum conditions crude oil distillation unit (AVCODU) from a typical refinery [Kaes G., 2002] is considered as the case study for above mentioned scope of this work. Various Heat exchanger Networks (HENs) has been developed by applying the process heat integration (HI) pinch approach. However, it has been estimated that 16.2 MW hot utility and 16.22 MW of cold utility can be saved in a year by revamping of pre-heating train of AVCODU. Furthermore, capital cost of revamping can be recovered within 2.3 year of plant operation. Keywords: oil atmospheric/vacuum distillation; heat integration, pinch points methodology, capital/operating costs, heat exchanger network (HEN) topology, find a HEN retrofit candidate, adopt a HEN retrofit solution from the candidates group
