Estimation of storage losses of fuels – Tanks software as a decisions – making tool for construction, maintenance and modernization of gasoline tanks

Estimation of storage losses of fuels - Tanks software as a decisions - making tool for construction, maintenance and modernization of gasoline tanks PORZYCKA-SEMCZUK K Please cite as: CHEMIK 2011, 65, 10, 974-982 TANKS is a Windows-based computer software program that estimates emissions formed as a result of volatile organic compounds storage, also including petroleum fuels. The estimations are possible for the tanks with fixed and floating roofs of different construction. There are presented some examples of this program application as a supplementary tool for making decisions concerning retrofitting or construction of new tanks designed for gasoline storage. Keywords: storage tanks, gasoline losses, emissions, floating roof, tanks retrofitting, VOCs Read more: pdf-icon...

Study of antioxidant properties of green tea extract

Study of antioxidant properties of green tea extract SIKORA E., OGONO WSKI J. Please cite as: CHEMIK 2011, 65, 10, 968-973 The aim of this work was the study of antioxidant properties of green tea extracts. Effect of kind of the solvent (ethyl alcohol, propylene glycol and water) and types of extraction (extraction in Soxlet apparatus and maceration) on the content of quercetin-3-rutinoside and the antioxidant efficiency of the extracts were investigated using UV-vis spectroscopy. The antioxidant properties were determinate on the basis of easurements of the colour intensity of thiocyanate complex which were formed in the mixture of linolic acid, FeCl2 and the extracts. The obtained results showed that alcoholic extract has the highest rutine concentration and exhibited the highest antioxidant properties.

Solid Lipid Nanoparticles ? characteristics, application and obtaining

Solid Lipid Nanoparticles ? characteristics, application and obtaining LASOŃ E., OGONO WSKI J. Please cite as: CHEMIK 2011, 65, 10, 960-967 Solid lipid nanoparticles (SLN) have attracted increasing attention as novel carrier systems for active substances, not only in farmaceutic, but also in cosmetic and food industry. Being in the market for about 20 years they gradually replace traditional colloidal systems while maintaining their advantages. In this paper general characteristic of solid lipid nanoparticles was done indicating their structure and properties. The most frequent production techniques was discussed and some examples of applying SLN to encapsulation of various drugs (with aspects of release) was given. Keywords: Solid Lipid Nanoparticles, SLN, bioactive substances, SLN production methods Read more: pdf-icon...

Shale gas ? unconventional natural gas

Shale gas ? unconventional natural gas MACHOWSKA H. Please cite as: CHEMIK 2011, 65, 10, 954-959 The need to ensure energy security for Europe and the world, and development of mining technologies has drawn attention to unconventional natural gas deposits, in particular the shale gas. Basing on the geological data and the gas potential analysis, it is assessed that there are considerable deposits of shale gas on the territory of Poland. However, the technology of mining unconventional gas requires superb geological, geochemical and environmental survey. Keywords: shale gas, natural gas Read more: pdf-icon...

The process of waste incineration in the tanning industry

The process of waste incineration in the tanning industry Wiecz orek -Ciur owa K., Famielec S., Woźny Z., Fela K Please cite as: CHEMIK 2011, 65, 10, 917-922 The article describes the conception of tannery waste treatment by combustion process in the specially designed system. The technology should provide tanneries with comprehensive solution for tannery waste problems. The additional advantage of the technology is the possibility to reuse energy from waste in tanning processes. Moreover, the characteristics of tannery waste in respect of its combustion as well as results of research carried out at the Faculty of Chemical Engineering and Technology are presented. Keywords: tannery waste, combustion, waste treatment,environmental protection Read more: pdf-icon  ...
