In 1998, the Board of the Swiss Federal Institute of Technology established the challenging vision of the 2000 W society. The goal is to reach, for Switzerland by the year 2050, an energy intensity target of 2000 Wyear/year/cap. Referring to a present inte ...
A computer system for the promotion of the rational use of energy in the industry has been developed. It combines the PINCHLENI software developed by the LENI (Laboratory of industrial Energy Systems) of the Swiss Federal Institute of Technology (Lausanne) ...
A method for the analysis of process energy requirements has been used to identify in an early design stage the potential process retrofit measures in an integrated pulp and paper mill. The minimum energy requirements (MER) of the process were computed by ...
The process design of a 10 to 20MWth Synthetic Natural Gas (SNG) production process from wood has been performed. Combining process modeling and process integration techniques, this study proceeds via the following stages: • thermodynamic modeling: mass, e ...
The integration of the utility system with all the plants of an industrial site is a mamor task for targeting the Minimum Cost of the Energy Requirement (MCER). Defining the target in terms of cost rather than in terms of energy introduces the problem of i ...
The selection and the optimal integration of the utility system is a major step of any energy integration study. It allows to determine an energy target based on the cost of the utilities rather than on energy. As a result, we obtain the final list of stre ...
Aerobic chemostat cultures of S. cerevisiae were performed at different diln. rates under energy (glucose) limitation or at various extents of energy excess imposed by a N limitation. Energy excess induced metabolic uncoupling under steady-state conditions ...
This paper presents a method combining a top-down and a bottom-up approach, which has been developed to track energy saving opportunities. The top-down modelling method aims at correlating the energy consumption with the final products and the auxiliaries ...
Energy efficiency in microarchitectures has become a necessity. Significant dynamic energy savings can be realized for adaptive storage structures such as caches, issue queues, and register files by disabling unnecessary storage resources. Prior studies ha ...
One of the most important conclusions of the energy integration techniques is that energy efficiency can only be analyzed with respect to the pinch point location of the system. Therefore, the problem boundaries cannot be limited to the chemical process le ...
