Optimisation 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 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 کاملIntegrated Fixed-Film/ Activated Sludge (IFAS) for Refinery and Petrochemical Wastewater Treatment Plant Upgrades
Integrated Fixed-Film/Activated Sludge (IFAS) technologies have been gaining wide popularity as an innovative and efficient treatment process for achieving nitrification in refining and petro-chemical wastewater treatment plants. IFAS technologies are sometimes referred to as Hybrid systems as the process combines the benefits of fixed film systems into the suspended growth activated sludge pro...
متن کاملThe BioCRACK Process - A Refinery Integrated Biomass-to-Liquid Concept to Produce Diesel from Biogenic Feedstock
Second generation biofuels, especially fuels from lignocellulose biomass, which are manufactured from non-food feedstock play a key role to reduce greenhouse gas emissions and the dependency on fossil oil. The bioCRACK process represents a new biomass-to-liquid concept to generate advanced biofuel by liquid-phase pyrolysis. As liquid heat carrier vacuum gas oil (VGO), an intermediate heavy oil ...
متن کاملDantzig-Wolfe and block coordinate-descent decomposition in large-scale integrated refinery-planning
The integrated refinery-planning (IRP), an instrumental problem in the petroleum industry, is made of several subsystems, each of them involving a large number of decisions. Despite the complexity of the overall planning problem, this work presents a mathematical model of the refinery operations characterized by complete horizontal integration of subsystems from crude oil purchase through to pr...
