A method has been developed to infer the wettability of steam-water-rock systems based on the relationship between permeability and capillary pressure by Purcell. The Purcell model was extended to two-phase flow to verify whether the wettability is a function of water saturation. The results calculated using the experimental data showed that the wettability index in drainage was greater than th...

The dangers posed by non-condensable gases (NCGs) in steam sterilisation processes have long been underestimated. Biological indicators, or the best chemical indicators on the market, do not signal the presence of a NCG content of up to 10% in a sterilisation process so long as there is mixing of steam and NCGs in the sterilisation chamber. Already back in 1963, Bowie and Dick (1) demonstrated ...

Botanicals are received in whole, non-sterile form. BI Nutraceuticals sterilizes, mills, and packages the ingredient in sturdy, safe containers before shipping to customers. Photo courtesy of BI Nutraceuticals Using Superheated Steam in Drying and Sterilization It seems counterintuitive to use water vapor in a process to remove water or to heat materials that can be damaged by moisture, but suc...

Brassica species are very rich in health-promoting phytochemicals, including phenolic compounds, vitamin C, and minerals. The objective of this study was to investigate the effect of different blanching (i.e., water and steam) and cooking (i.e., water boiling, steam boiling, microwaving, and stir-frying) methods on the nutrient components, phytochemical contents (i.e., polyphenols, carotenoids,...

Solar energy is a good solution for energy-deficiency problems, especially in regions such as rural areas in the Middle East that have not been electrified yet or are under electrification. In this paper, with the aid of a Computational Fluid Dynamics simulation, we propose a system that comprises a trough solar concentrator and a pipe—with flowing water—that is set in the concentrator focus. T...

Abstract: The paper presents the research results related to control of the steam boiler parameters: drum level, furnace pressure and steam pressure. It was developed the mathematical model of the water-steam system and furnace part of the boiler. Also, the paper presents the algorithm for real time detection of model parameter variations. In this context a correction method, validate through s...

DC lOO%-steam plasma characteristics were investigated for the application of halogenated hydrocarbon decomposition because steam plasmas are chemically reactive. However, plasma system generally requires complex subsystems such as steam generators and cooling units. The presented steam plasma system is a portable light-weight plasma generation system that does not require any gas supply unit. ...

The genus Boswellia is one of the 17 genera belonging to Burseraceae family. In this study resin of Boswellia carteri birdwoodcollected or purchased from Tehram herbal Market as a food and non-food for chemical analysis. The essential oils of the resins of Boswellia carteri birdwoodobtained by different methods of distillation (water distillation, steam distillation and hydro-steam distillation...

this paper deals with a failure investigation of boiler feed pump’s shaft of a steam power plant. boiler feed water pump is a specific type of pump used to pump, feed water into a steam boiler and is one of most important part of steam power plants. feed pumps failure may cause failure of another part of steam power station, therefore keep them safe is an important problem. there are 12 feed pu...
