The HPV data file is of similar size than VLE. It contains different types of complete (x,y,P,T) or incomplete data for
components with a normal boiling point below 0°C. Data reported in form of Henry or other coefficients are not included. These can be found in
the GLE data bank. Mixtures with electrolytes (solvated ions) are not included as these can be found in the ELE and EGLE data banks.
This data bank is of great importance for customers working in the field of
- gas processing, LNG applications
- air liquification
- supercritical fluid extraction
- reaction engineering involving low boiling components and two phase
(vapor-liquid) reactors
- refrigeration and heat pumps
- risk assessment (e.g. maximum pressure build-up)
- ...
The plot on the right shows a typical example for data sets from the HPV data bank for the system CO2(1) - ethane(2) together with curves
predicted by the VTPR equation of state. For convenience, critical data of the mixture from DDB-CRI and azeotropic data from DDB-AZD were
included in the plot.
The following table gives an overview of the number of data sets for the most important light boiling components in DDB-HPV (January 2009). To
stress the importance of using both DDB-HPV and DDB-GLE, the number of datasets in the latter segment of the DDB is also included in the table.
The following figure shows experimental and calculated (SRK) solubilities for the systems CO2(1) - octanol(2) (left hand side) and
CO2(1) - naphthalene(2) (right hand side) at different temperatures as a function of pressure to illustrate the change of vapor phase concentration of the heavy boiling
component with pressure for supercritical fluid extraction of liquids (left hand side) and solids (right hand side).
DDB-HPV contains 31,671 data sets (273,087 data points) from 3,498 references with data for 1,564
components and 4,450 different systems (3,723 binary, 981 ternary and 146 quaternary systems) (Version 2011).
VLE contains 31,649 data sets for 1,773 components from 6,634
references and 9,917 different systems (8,156 binary, 1,536
ternary and 149 quaternary systems) (Version 2011).
