What is DIPPR Project 801 Full Version?




Are you looking for a reliable source of thermo-physical property data for process engineering and design? Do you want to access a comprehensive database that meets industry needs for accurate and complete data in a rapidly changing business and technical environment? If so, you might be interested in learning more about DIPPR Project 801 Full Version.




dippr project 801 full version



DIPPR stands for Design Institute for Physical Properties, a pre-competitive research consortium that was established in 1977 by AIChE (American Institute of Chemical Engineers). The mission of DIPPR is to develop, expand, and improve a database of thermo-physical properties for industrially important chemicals used in chemical process and equipment design.


Project 801 is one of the main projects of DIPPR that focuses on providing critically evaluated thermo-physical property data for over 2000 pure compounds. The full version of Project 801 database contains data that are exclusive to DIPPR members for at least five years before they are released to non-members under various licensing options.


The benefits of using DIPPR Project 801 Full Version are manifold. First, you can access data that are based on a proprietary evaluation methodology that uses a systems approach to triangulate on the best values from all available sources[^1^ Second, you can access data that are comprehensive and consistent, covering a wide range of properties and conditions for each compound. The properties include thermodynamic, transport, phase equilibrium, and reaction data, as well as molecular structure, critical constants, and safety information. The conditions include temperature, pressure, concentration, and phase.


Third, you can access data that are important for process engineering and design, such as vapor pressure, heat capacity, viscosity, thermal conductivity, surface tension, enthalpy of vaporization, enthalpy of formation, Gibbs energy of formation, solubility parameter, and many more. These data can help you perform various tasks such as process simulation and optimization, equipment sizing and selection, process safety and environmental analysis, and product quality and performance evaluation.


How does DIPPR Project 801 Full Version work?




Now that you know what DIPPR Project 801 Full Version is and why it is beneficial, you might be wondering how it works. How does DIPPR evaluate and recommend thermo-physical property data? What are the components and metadata of Project 801 database? What are the types and number of properties included in Project 801 database? Let's find out.


Methodology: How does DIPPR evaluate and recommend thermo-physical property data?




DIPPR uses a rigorous and systematic methodology to evaluate and recommend thermo-physical property data for Project 801 database. The methodology consists of four main steps:


  • Data collection: DIPPR collects data from various sources such as literature, databases, experimental measurements, theoretical calculations, and expert opinions. DIPPR also performs its own experimental measurements for some compounds using state-of-the-art equipment and methods.



  • Data evaluation: DIPPR evaluates the quality and reliability of the collected data using criteria such as accuracy, precision, consistency, completeness, and traceability. DIPPR also compares the data with other sources and performs statistical analysis to identify outliers and trends.



  • Data correlation: DIPPR correlates the evaluated data using empirical or theoretical models that best fit the data over the relevant range of conditions. DIPPR also provides equations of state (EOS) for some compounds to describe the thermodynamic behavior of fluids.



  • Data recommendation: DIPPR recommends the best values for each property based on the correlated data and the EOS. DIPPR also provides uncertainty estimates for each recommended value to indicate the confidence level of the data.



DIPPR updates its evaluation and recommendation methodology periodically to incorporate new data sources, models, methods, and standards.


Structure: What are the components and metadata of Project 801 database?




Project 801 database consists of two main components: a member database and a licensed database. The member database contains data that are exclusive to DIPPR members for at least five years before they are released to non-members under various licensing options. The licensed database contains data that are available to non-members through different licensing options such as single-user license, site license, or corporate license.


Each component of Project 801 database has a similar structure that includes the following metadata for each compound:


  • Name: The common name of the compound.



  • CAS number: The Chemical Abstracts Service registry number of the compound.



  • Formula: The chemical formula of the compound.



  • Molecular weight: The molecular weight of the compound in g/mol.



  • Structure: The molecular structure of the compound in SMILES format.



  • Synonyms: The alternative names of the compound.



  • Family: The chemical family or class of the compound.



  • Source: The source or origin of the compound.



  • Purpose: The purpose or use of the compound.



  • Critical constants: The critical temperature (Tc), critical pressure (Pc), critical volume (Vc), critical compressibility factor (Zc), critical density (ρc), acentric factor (ω), and dipole moment (μ) of the compound.



  • Safety information: The flash point (Tf), autoignition temperature (Ta), lower flammability limit (LFL), upper flammability limit (UFL), lower explosive limit (LEL), upper explosive limit (UEL), heat of combustion (ΔHc), heat of explosion (ΔHe), toxicity information (LD50), hazard statements (H), precautionary statements (P), signal word (SW), hazard pictograms (HP), Globally Harmonized System of Classification and Labelling of Chemicals (GHS) codes, National Fire Protection Association (NFPA) codes, and Material Safety Data Sheet (MSDS) of the compound.



  • References: The references or sources of the data for the compound.



In addition to the metadata, each component of Project 801 database also includes the recommended values and uncertainty estimates for each property of each compound over the relevant range of conditions. The properties are grouped into different categories such as thermodynamic, transport, phase equilibrium, and reaction data. Each property has a unique identifier (ID) and a description that includes the units, symbols, and definitions of the property.


Properties: What are the types and number of properties included in Project 801 database?




Project 801 database includes over 40 types of properties for each compound, covering a wide range of thermo-physical phenomena and applications. The properties are divided into four main categories:


  • Thermodynamic data: These are the properties that describe the energy and entropy aspects of a system, such as heat capacity, enthalpy, entropy, Gibbs energy, Helmholtz energy, fugacity coefficient, and excess properties.



  • Transport data: These are the properties that describe the mass, momentum, and heat transfer aspects of a system, such as viscosity, thermal conductivity, diffusion coefficient, surface tension, and thermal diffusivity.



  • Phase equilibrium data: These are the properties that describe the equilibrium between different phases of a system, such as vapor pressure, vapor-liquid equilibrium (VLE), liquid-liquid equilibrium (LLE), solid-liquid equilibrium (SLE), solid-vapor equilibrium (SVE), and solubility.



  • Reaction data: These are the properties that describe the chemical reactions and kinetics of a system, such as reaction rate constant, activation energy, reaction enthalpy, reaction entropy, reaction Gibbs energy, and equilibrium constant.



The number of properties included in Project 801 database varies depending on the availability and relevance of the data for each compound. However, on average, Project 801 database contains about 25 properties for each compound in the member database and about 15 properties for each compound in the licensed database. The table below shows some examples of the properties and their IDs for a sample compound (acetone) in Project 801 database.
