A crude distillation unit model suitable for online applications
A steady state, multicomponent distillation model particularly suited for fractionation of crude oil has been developed based on equilibrium stage relations. For a mixture of C components, the present formulation uses Cq3 iteration variables namely the mole fractions of the components, temperature, total liquid and total vapor flow rates on each stage. This choice of variables makes the present...
متن کاملThermodynamic and Thermoeconomic Optimization of an Absorption Refrigeration System integrated with Refinery Crude Oil Furnace
In the present study, exhaust gases from Tehran refinery crude oil furnace are used in a Heat Recovery Steam Generator (HRSG)for generating steam. Then, the steam is directed to a double effect absorption refrigeration cycle to produce cooling. To meet the object, mass and energy balance equations of the coupling is carried out for both the HRSG and the absorption chiller and unknown thermodyna...
متن کاملDynamic Simulation and Control: Application to Atmospheric Distillation Unit of Crude Oil Refinery
Nowadays dynamic simulation has become a key tool in the study of the behaviour of almost every process. The benefits that proper modelling can bring to any industry have a very high value, especially one that cannot be directly measured, which is the increase of knowledge about the process. The simulation allows the study of transient states of complex processes without the need of leading the...
متن کاملOptimisation of Existing Heat-integrated Refinery Distillation Systems
Existing refinery distillation systems are highly energy-intensive, and have complex column configurations that interact strongly with the associated heat exchanger network. An optimisation approach is developed for existing refinery distillation processes. The optimisation framework includes shortcut models developed for the simulation of the existing distillation column, and a retrofit shortc...
متن کاملGlobal optimization for scheduling refinery crude oil operations
In this work we present an Outer-Approximation algorithm to obtain the global optimum of a nonconvex Mixed Integer Nonlinear Programming (MINLP) model for the scheduling of crude oil movement at the front-end of a petroleum refinery. The model relies on a continuous time representation making use of transfer events. The proposed technique focuses on effectively solving a Mixed Integer Linear Pr...
