Estimation of Physical Properties and Composition of Hydrocarbon Mixtures

2003
Economical and optimum design and operation of refinery units and related industry largely depend on accurate values of thermodynamic and physical properties of related fluid mixtures used in process simulations. Thermodynamic and physical properties are also known as thermophysical or simply physical properties and include but not limited to PVT ...

Local composition modelling of the thermodynamic properties of refrigerant and oil mixtures

International Journal of Refrigeration, 1996
Abstract Six local composition models of the thermodynamic behaviour of mixtures are described. Using data from the literature and a non-linear regression analysis, a comparison of the predictive abilities of the models is undertaken for R12, R22, R134a and R125 with various oils.

Properties of Gas‐Generating Mixtures Related to Different Fuel and Oxidizer Compositions

Propellants, Explosives, Pyrotechnics, 2003
AbstractThis work focuses on solid energetic materials designed to produce high‐pressure gas for pressurizing or inflating devices. In small gas generators sodium azide is often used. Unfortunately, this chemical exhibits drawbacks concerning toxicity and yield of gas. Other classical gas‐generating agents are double base propellants.

Influence of Ti and B powder mixing modes on mixture properties and SHS composite microstructure

Izvestiya vuzov. Poroshkovaya metallurgiya i funktsional’nye pokrytiya, 2020
The paper studies the influence of mixing modes for titanium and boron powder mixtures with the 81.5 % Ti + 18.5 % B composition in a ball mill on the process characteristics of mixtures, combustion parameters, and microstructure of SHS composites. It is shown that the dependence of the electrical resistivity on the density of charge compacts for the ...

Effect of feldspar concentrate composition on structure and properties of ceramic mixtures

Glass and Ceramics, 1999
Feldspar concentrates produced from concentrated rocks of Karelia are investigated as components of hard porcelain mixtures. The effect of feldspar concentrates having different ratios of potassium and sodium oxides, the mineralogical composition, and the structural specifics on the structure and properties of porcelain mixtures is studied.

COMPOSITE ADHESIVE MIXTURES BASED ON CEMENT: PROPERTIES, APPLICATIONS, AND ADVANCEMENTS

Composite adhesive mixtures based on cement have gained widespread use in construction and other industrial applications due to their superior bonding properties, durability, and versatility. This thesis aims to explore the formulation, mechanical properties, and potential applications of cement-based adhesive mixtures.

Production and properties of thermosetting composites based on wood and unsaturated- polyester mixtures

Bioresource Technology, 1994
Abstract Composites based on wood and unsaturated polyester display, prior to functionalization preceded by an ozone pre-treatment of wood, a higher constraint to flexion rupture, an improved Rockwell toughness and lower hydrophilic and flexibility characteristics than does a pure polyester matrix. The introduction of a hydrophobic additive decreases
