3 Things to Know about Yaws’ Critical Property Data for Chemical Engineers and Chemists
Amanda Moreno
August 17, 2012 Read this quick Q&A with Sasha Gurke, SVP and co-found of Knovel, as he highlights the value of Knovel’s latest database! This fresh content is offered exclusively to Knovel customers as part of Knovel’s Critical Content.
K-Exchange: Why should chemical engineers use Yaws’ Critical Property Data for Chemical Engineers and Chemists as a primary reference guide?
Sasha Gurke: There are 3 important features of Yaws’ Critical Property Data for Chemical Engineers and Chemists:
#1 This data is comprehensive– This database has by far the largest number of properties and compounds among what is available on the web today. The database currently includes 85 tables with more than 5,000 inorganic substances, more than 34,000 organic substances and more than 293,000 records. Compared to Section 2 of Perry’s, Yaws’ Critical Property Data for Chemical Engineers and Chemists has deeper coverage—approximately 5 to 10 times more coverage. Knovel focused on this data intensive section, based upon customer use, and significantly improved it.
#2 The vast majority of data is highly interactive and multi-point i.e., properties are presented as functions of temperature, concentration and pressure. Users can interpolate data.
#3: This data is high -quality: Carl L. Yaws is a well-known and trusted author with industrial experience. He has published a number of books with the same properties. His titles are among the most used titles on Knovel today! Knovel has a 3-step validation process for all the data. The first step is a review by an independent expert; the second step is a three-level internal quality assurance review. After these rounds of reviews, edits are exchanged between Knovel and the author before the content is finalized and published.
K-Exchange: What are your plans for this database?
Sasha Gurke: We will increase content. The next addition of more than 90 titles will launch at the end of the year. We also monitor the usage of this database, so we can see where to deepen and expand content in the future, based on customer need. Nothing about this data is static.
KX: Who benefits most from the database?
SG: Chemical and process engineers, chemists, environmental engineers and safety engineers will get a lot out of this new database.
For example: Process engineers designing chemical processes will use thermodynamic properties such as enthalpy of formation; chemical engineers selecting equipment for a chemical plant will use properties such as viscosity at different temperatures and specific heat; environmental engineers will use this database for Henry’s law constants, octanol-water partition coefficient, bioconcentration factor, and threshold limit value and permissible exposure limit; safety engineers will use this database for flammability limits, flash points, and autoignition temperatures.
