Systematic errors in data evaluation due to ethanol stripping and water vaporization

Urs von Stockar

Systematic errors due to the neglect of water and/or ethanol partition between liq. and gaseous phases are discussed for bioreactors equipped with or without a condenser. Both water vapor and ethanol vapor are present in the off-gas leaving the condenser. ...

First and Second Law Based Fuel Minimization in a Batch Furnace

This paper presents results for the minimization of fuel consumption in a batch furnace. Several different criteria are used and minimized with respect to time- dependent process and control variables. As would be expected, the results show that globally t ...

An Optimization Tool of Hybrid Type EV Systems.

Daniel Favrat, Adam Molyneaux

An optimization tool to identify optimum structure/parameters of hybrid electric vehicles (hereafter abbreviated as HEV) is proposed, which can take account of various criteria regarding environmental impacts, cost minimization, or minimum fuel consumption ...

Model discrimination for reactions with stop-effect

Albert Renken, Olivier Wolfrath

The stop-effect, a drastic increase of the reaction rate when the feed concn. of a reactant is switched to zero, was studied for the dehydration of ethanol to ethylene on y- alumina at 180 and 200 DegC. Two basic models exist in the literature to describe ...

Spectroscope method for determining the concentration of ethanol in beverages

Luc Thévenaz

A method and apparatus serve to determine spectroscopically a concentration of ethanol in a test sample of an alcoholic aqueous beverage. The determination is based upon providing calibration data which establish a relation between (A) a plurality of trans ...

R–502 and Two Near-Azeotropic Alternatives. Part I: Intube Flow Boiling Tests.

John Richard Thome, Daniel Favrat

Flow boiling experiments for two new non-azeotropic, three-component refrigerant mixtures (HP80 and HP62) and R-502, the azeotropic refrigerant binary mixture they are replacing, have been carried. Comparative results show that local flow boiling heat tran ...

Intube Flow Boiling of R–502 and Two Near-Azeotropic Alternatives.

John Richard Thome, Daniel Favrat

Flow boiling experiments for two new non-azeotropic, three-component refrigerant mixtures (HP80 and HP62) and R-502 have been carried out inside a 12 mm bore, horizontal tube. Local boiling coefficients for HP62 are slightly larger that those for R-502 und ...

D-Ala2-Met5-enkephalinamide impairs the acquisition of ethanol preference without influencing sucrose preference

Maria del Carmen Sandi Perez

The effects of subcutaneous (SC) administration of D-Ala2-Met5-enkephalinamide (DAME) (1, 10 and 100 micrograms/kg), synthetic analog of Met-enkephalin, on the acquisition of ethanol preference were studied in male Wistar rats. Under our procedural conditi ...

Effects of the kappa opioid receptor antagonist MR-2266-BS on the acquisition of ethanol preference

Maria del Carmen Sandi Perez

Using a paradigm by which rats forced to drink a weak ethanol solution (2.5% w/v) (conditioning session) develop ethanol preference in consecutive retention testing days, the effects of the administration of the kappa opioid antagonist MR-2266-BS, prior to ...
