Petelýza - chemická recyklace PET
Veselý, Václav
2009 - Czech
Předkládaná studie se zabývá procesem výběru možných investorů pro případný prodej licence technologie na recyklaci PET lahví metodou PETELÝZA. Stav vývoje technologie je shrnut v investiční studii vypracované projekční organizací Chemoprag, s.r.o. Praha. Technologie je chráněna třemi patentovými přihláškami PV 2006-313, PV 2006-550 a PV 2008-602. Pro rozhodování o investici v oboru recyklace je pro investora důležitá znalost zdrojů a odbytů. Tato studie se touto problematikou nezabývá. Právě tak neřeší vývoj inflace. This report treat of selection of clients on chemical recycling process PETELYSE for recycling PET botles. Investment study summarised results of research anad development of technology true to scale 100 kg PET per hour. The technologie is protected by 2 patents. The marketing of produkts is importanr for the investments in recyclation technology. This study treat not of produkt selling and source of PET material

Surfactant Dissolution Using High Pressure Micromixer In-line Spectrometry at Pilot Scale Flow Rates
Křišťál, Jiří; Simoncelli, A.
2009 - English
We report that the highly viscous paste can be dissolved very quickly and efficiently in microSAR mixers with very low pressure losses. Inline measurements, including spectroscopy, in the HP rigs was easily organized by reapplication of the FMU elements.

Theory of Electrodiffusion Friction Probes in Microdisperse Liquid 8. Effect of Apparent wall Slip and Insulating Gaps on the Directional Characteristics
Wein, Ondřej
2008 - English
Insulated insertions between individual segments of direction-sensitive electrodiffusion friction probes attenuate the directionalsensitivity. Quantitative study of this effect by Wein and Wichterle (1989) for Newtonian liquids has been extended in a recent research report (Wein 2007) for the microdisperse liquids, displaying the Apparent Wall Slip, i.e. a non-linear velocity profile close to solid surfaces. In the present research report, this theory is used to the simulation calculations of directional characteristics for a class of 3-segment electrodiffusion friction probes with the insulating insertions. Rather realistic model of non-ideal 3-segment direction-specific probes is tested by comparison of the predictions with experimental data about an actual 3-segment probe in both homogeneous and microdisperse liquids. Isolační vložky mezi jednotlivými segmenty směrově citlivých elektrodifuzních čidel zeslabují jejich směrovou citlivost. Kvantitativní studie tohoto efektu od Weina a Wichterleho (1989) pro Newtonské kapaliny byla v předchozí výzkumné zprávě (Wein 2007) rozšířena na mikrodisperzní kapaliny, vykazující zdánlivý skluz při stěně, tj. nelinární rychlostní profil v blízkosti pevných povrchů.V předkládané výzkumné zprávě je tato teorie využita k simulačním výpočtům směrových charakteristik pro jistou třídu třísegmentových elektrodifuzních frikčních čidel se zahrnutím vlivu isolačních vložek. Jedná se o první analytickou studii vlivu isolačních mezer a zdánlivého skluzu na směrové charakteristiky. Současně je v simulačních výpočtech otestován poměrně realistický model 3-segmentových směrově specifických čidel s neideální geometrií. Výsledné předpovědi jsou porovnány s experimentálními data o chování reálné třísegmentové sondy jak v homogenních tak i mikrodisperzních kapalinách.
