An application of a decision tree for assessing effects from exposures to multiple substances to the assessment of human and ecological effects from combined exposures to chemicals observed in surface waters and waste water effluents

A decision tree has been developed for evaluating risks posed by combined exposures to multiple chemicals. The decision tree divides combined exposures of humans and ecological receptors into groups where one or more components are a concern by themselves, ...

Application of Exergy Analysis in Energy Requirements Assay of the Typical Process Unit Operations of Chemical Industries

Amélie Courjon

This project proposes a method based on exergy analysis for considering energy efficiency problems. Because exergy is not a concept frequently used by industrials attention has been paid to go through what is exergy and how it can be so useful to enhance t ...

Base case process development for energy efficiency improvement, application to a Kraft pulping mill. Part II: Benchmarking analysis

François Maréchal

A new procedure for benchmarking analysis has been developed to evaluate the energy efficiency of a chemical process. Benchmarking is performed to identify process inefficiencies before developing energy enhancement measures. The new procedure combines typ ...

Mixing efficiency and energy consumption for five generic microchannel designs

Albert Renken, Lioubov Kiwi, Madhvanand Namadeo Kashid

Mixing is an essential part of chemical processes. In the present work, homogeneous mixing at relatively high throughput for a single microchannel (of 1-18 mL/min) was investigated in microchannels with different dimensions, cross sections and mixing eleme ...

Advances in the Theory of Control, Signals and Systems with Physical Modeling

Philippe Müllhaupt, Jean Lévine

In the 60's, control, signals and systems had a common linear algebraic background and, according to their evolution, their respective backgrounds have now dramatically differed. Recovering such a common background, especially in the nonlinear context, is ...
