Obiettivo A Transport Properties Estimation System (TPES) for pure hydrocarbons and their mixtures has been developed. In its final version this computational system includes a Data Bank and a Library of Prediction Subroutines for the determination of hydrocarbons properties data. The estimation methods, their algorithmic formulation and the production of the main computer codes along with their integration and validation represent the achieved ultimate objective of the project. The area of application extends to liquid and gaseous hydrocarbons and some inorganic substances (pure or mixtures) used in Natural Gas and Oil Industry. Coupling of TPES and existing CAE and CFD codes is possible by means of suitable flexible interface facilities.Data Base Properties Sheets and codes for the prediction of various properties of hydrocarbons (which however have not been integrated yet into a unique product) are already available and can be applied in connection of existing computer aided engineering codes in the natural gas and oil industry.The project can be described by its stages structure consisting of the completed six main stages :I COMPILATION OF PROPERTIES. The planned amount of the properties data has been collected, evaluated, classified, prepared and introduced into the data bank.Sources tables of parameters data, and physical properties for more than fourty pure substances are also presented in the internal and interim project reports.II PROPERTIES PREDICTION METHODS AND PROCESSORS FOR DATA ESTIMATION. Subroutines LIbrary consisting of several stand-alone modules has been designed and all the programmes have been tested and are able to produce transport and physical properties data for pure hydrocarbons and some inorganic compounds, or mixtures of them related to Oil and Natural Gas systems.III PROPERTIES DATA BASE. Deliverable of this stage is a Data Base and DB data fields containing all necessary properties, coefficients and parameters involved in the previous stages. In addition the list of substances has been extended due to special industrial applications. In this regard further extension to substances not directly related to oil and natural gas was necessary. The primary and the main computed properties part is completed whilst the computed properties part can be continuously compiled and updated by the results of stage II, if further extension would be desired.IV TESTING, INTEGRATION, VALIDATION AND APPLICATIONS. Extensive and validation procedures have been performed fulfilling on conditions set by quality requirements as regards the certainty of the technical and physical results, through verification tests based on computational examples encountered in the literature, and real applications cases. Results of the validation procedure are stored and presented in internal and, partially, in interim reports. Definition of new test cases of industrial interest and long run testing of the codes efficiency and certainly has been continuously compiled. This stage covered approximately the total project duration and was intensified during the one year extension period.V DOCUMENTATION.VI PROJECT ORGANIZATION AND MANAGEMENTThe project organization has had to fulfill requirements dictated by the complex nature of the project, which covered different technological areas from petroleum engineering applications to properties prediction methods and to software tools development. As a consequence it was necessary to structure the whole project work in well defined activities with specific deliverables and documentation.
