Washability and Thermal Properties of Oltutaşı Wastes
Bawani, Muhammad Raheel; Arol, Ali İhsan; Tozsin, Gülşen; Akbulak, Bora; Torun, Abdülvahit (null; 2019-11-02)
Oltutaşı (Jet Stone), also known as black amber, is a fossilized, organic and natural material formed as a result of the transformation of certain trees under high pressure. It is called Oltutaşı because its occurrences are mostly located in the Oltu district of Erzurum. Generally, it is mined by small miners from nearby villages using rather primitive methods. After a rough sorting at the mine site, Oltutaşı is mostly used in the manufacturing of worry beads (tespih) and to a lesser extent, certain ornamen...
Cleaning rate in the uniform cleaning stage for whey protein gel deposits
XİN, H; Chen, XD; Özkan, Necati (2002-12-01)
The removal of a thermally induced whey protein concentrate (WPC) gel layer from the inner surface of a stainless steel tube was determined continuously and non-invasively by a rapid UV spectrophotometric method. Based on mass transfer theory and polymer dissolution concepts, the constant cleaning rates in the uniform stage were predicted. The viscosity and solubility of WPC gels at different temperatures were measured and used in the modelling prediction. The deviation of the prediction from the experiment...
Washing theory for nonequilibrium stages
Tosun, I (Wiley, 1996-06-01)
A new approach for the determination of concentrations in the case of nonequilibrium washing stages is presented. Each washing stage is assumed to consist of series of mixing cells, and the conservation of solute mass is solved by Laplace transformation. The simplicity of the resulting equations makes this approach more practical than the existing one.
Wash-Coat Development for Lean-Burn Engine-Exhaust Aftertreatment: Incorporation of Binder to Pd Supported on Sulfated Zirconia
Majumdar, Sreshtha Sinha; Çelik, Gökhan; Ozkan, Umit S. (null; 2015-07-19)
As the environmental regulations are getting more stringent, it is of great importance to develop a catalytic aftertreatment system for natural gas-fired lean-burn engines to reduce the emissions of nitrogen oxides (NOx), unburned hydrocarbons (CH4, C2H6, and C3H8) and carbon monoxide efficiently. We have developed a dual-catalyst aftertreatment system which utilizes the hydrocarbons present in the exhaust streams of lean-burn engines for reducing NOxemissions. The dual-catalyst aftertreatment system is a p...
