Dehydration of alcohol solutions obtained from a solvent recovery process by pervaporation
Büküşoğlu, Emre; Yılmaz, Levent; Department of Chemical Engineering (2010)
Solvent recovery is gaining importance in the chemical production processes to reduce the costs and because of environmental concerns. Therefore separation schemes for recovery and recycle of solvents used in printing and packaging industry were developed. However, a low value by-product, mainly ethyl alcohol and isopropanol, is obtained during the solvent recovery process. If the water concentration of this mixture is decreased below 0.1% by weight, the value of it increases significantly. To dehydrate thi...
Dehydration of aqueous aprotic solvent mixtures by pervaporation
Sarıalp, Gökhan; Kalıpçılar, Halil; Yılmaz, Levent; Department of Chemical Engineering (2012)
Aprotic solvents are organic solvents which do not easily react with a substance dissolved in it and they do not exchange protons despite of their high ion and polar group dissolving power. Therefore, this characteristic property makes aprotic solvents very suitable intermediates in many industries producing pharmaceuticals, textile auxiliaries, plasticizers, stabilizers, adhesives and ink. Dehydration of these mixtures and recirculation of valuable materials are substantial issues in industrial application...

Dehydration of Industrial Byproduct Solutions for Recycling via Pervaporation-Adsorption Hybrid Process
Büküşoğlu, Emre; Kalıpçılar, Halil; Yılmaz, Levent (2018-02-14)
Dehydration of used solvents in the printing and packaging industry is required in order to reuse or increase the commercial value of the solvents. In this study, a pervaporation-liquid-phase adsorption hybrid process for dehydration of a low-value byproduct solution obtained from a real operation was examined. The byproduct solution contained water varying in the range of 1-11.5 wt %, and the majority of the rest is ethanol and isopropanol with minor components such as ethyl acetate and methoxy propanol. W...
Detoxification of aflatoxin B1 in peanut meal by heating and gamma irradiation
Aygün, Şükran Gizem; Bozoğlu, Faruk; Şensoy, İlkay; Department of Food Engineering (2015)
Aflatoxin is one type of mycotoxin, which is synthesized by some molds as by-products under certain conditions and needed to be controlled because of several health risks when present in foods and feeds. Due to these health related effects, prevention of aflatoxin in food and feed is essential. According to the Turkish Food Codex Communiqué on Undesirable Substances in Feed, the maximum limit of aflatoxin B1 in feed materials is defined as 0.02 ppm. In case of unavoidable aflatoxin contamination, there are ...
