Knovel Expands Yaws' Critical Property Data for Chemical Engineers and Chemists

Database Addresses Market Need for Updated, User-Friendly Chemical Properties Information

NEW YORK, NY--(Marketwire - Jan 9, 2013) - Knovel, a leader in providing a Web-based application that integrates technical information with analytical and search tools, today announced an expansion to Yaws' Critical Property Data for Chemical Engineers and Chemists which Knovel launched in July 2012. The expanded database now includes data on superheated, saturated and subcooled fluids, mixtures, refrigerants and various materials used in chemical plant construction and equipment design -- information previously unavailable in a single reference database.

"Today's expansion of Yaws' Critical Property Data for Chemical Engineers and Chemists reflects the demand for dynamic technical content and ever-improving resources," said Sasha Gurke, Knovel's senior vice president and co-founder. "With the additional coverage of mixtures, refrigerants, alloys and construction materials, chemical engineers will be able to use this database for a wider variety of applications."

Adding to Yaws' initial release offering more than 5,000 inorganic and 34,000 organic substances as well as 293,000 records, the database now includes an additional 90 tables and 5,000 records of property data for mixtures, refrigerants and miscellaneous solids and liquids. Notable additions:

  • Physical and thermophysical properties of mixtures, including densities of aqueous solutions and total pressures of aqueous solutions.
  • Thermophysical properties of superheated, saturated and subcooled fluids over a range of pressures and temperatures including vapor pressure, densities and volumes, surface tension and compressibility factors.
  • Thermodynamic properties of superheated, saturated and subcooled fluids, over a range of pressures and temperatures including internal energy, heat capacity, enthalpy, entropy at constant volume of liquid and of gas.
  • Transport properties of superheated, saturated, and subcooled fluids, including speed of sound, Joule-Thomson coefficient of liquids and gases, thermal conductivities, and viscosities.
  • Thermophysical properties of refrigerants, including vapor pressure, densities, volumes, surface tension and compressibility factors.
  • Thermodynamic properties of refrigerants, including internal energy, enthalpy, entropy and heat capacity.
  • Transport properties of refrigerants, including speed of sound, thermal conductivity, viscosity, Prandtl number, and Joule-Thomson coefficient.
  • Thermodynamic and transport properties of solutions and miscellaneous solids and liquids, including R-value, heat capacity for miscellaneous solids and miscellaneous liquids, thermal conductivity for building and insulation materials, various stainless steels and pure metals and alloys, and viscosity of aqueous solution for inorganic and organic compounds. 

Yaws' Critical Property Data closely follows the content in Section 2 of Perry's tables, the most frequently used section of Perry's on Knovel. However, Yaws' database provides information in a format that's easier to use, more discoverable and interactive. Features of this database include:

  • Interactive graphs providing visualization of data points and the ability to calculate and plot additional data values as functions of variables such as temperature and pressure.
  • Interactive tables with sort and filter capabilities, allowing for easy assessment and comparison of data. 

"Chemical engineers have been using Perry's as their chemical properties resource for decades, but there is a need for chemical properties resources that offer usability and interactivity enhancements," said Dr. Vadim Lvovich, President, Electrochemical Sciences Consulting. "The scheduled updating and advanced features of The Yaws' Critical Property Data for Chemical Engineers and Chemists clearly separates it from its competition and ensures that engineers always have the most up-to-date information on chemical properties."

This is the second release of Yaws' Critical Property Data for Chemical Engineers and Chemists, part of Knovel's Critical Content line. Additional properties and substances will be added over time.
