A methodology is proposed to target the retrofit of utility system and heat exchanger network (HEN) of large-scale chemical plants. The methodology is based on the Mixed Integer Linear Programming (MILP) formulation for the optimal site utility integration ...
Mixing of fresh (river) water and salty water (seawater or saline brine) in a control fashion would produces an electrical energy known as salinity gradient energy (SGE). Two main conversion technologies of SGE are membrane-based processes; pressure retard ...
This work presents a synthesis method that leads to the preliminary design of industrial energy systems. Such systems are composed of several technologies that transform, through a set of physical unit operations, raw materials and energy into products and ...
This diploma project is a joint effort between Industrial Energy System Laboratory (LENI) of EPFL and CanmetENERGY-Varennes of Natural Resources Canada on the application of advanced process integration methods for the optimal water and energy integration ...
A new methodology is herein suggested to target the retrofit of utility system and heat exchanger network (HEN) of large-scale chemical plants for energy eciency improvement purposes. The methodology is based on the optimal site energy conversion unit inte ...
This report presents some approaches to modelize urban energy systems. More precisely, as a first step, a clear definition of what is an urban energy system model is exposed before listing the main tech- niques of modelization. With the goal to run a case ...
The conversion of microalgae biomass into biofuels is a quite well explored field of research. Due to high photosynthetic efficiency, microalgae are considered as a potential feedstock for next-generations biofuel conversion processes. This paper addresses ...
The objective of this master project is to develop model for the solar driven supercritical desalination plant. Furthermore we propose a possible system integration and examination of its performance in terms of energy and cost effectiveness. The model sim ...
Problems dealing with the design and the operations of gas transmission networks are challenging. The difficulty mainly arises from the simultaneous modeling of gas transmission laws and of the investment costs. The combination of the two yields a non-line ...
This study presents a methodology based on the process integration techniques and multiple representation of heating and cooling requirement concept to improve the energy efficiency of a large-scale chemical plant. Considering the difficulties of data gath ...
