| Summary: | 碩士 === 東海大學 === 化學工程學系 === 90 === This study, utilizing the common gateway interface (CGI), constructs a server system to provide the search and estimation of the properties of gases and liquids. It is a typical common gateway interface for chemical industry application (CGICIA).
The property search and estimation system is written in C++ programming language. Major property search and estimation are heat capacity, saturated vapor pressure, viscosity, thermal conductivity, diffusion coefficients and so on. A data bank consisting of 618 compounds with more than 20 basic data or parameters for each compound is built. For property estimation, parameters are retrieved form data bank and plugged into various empirical or semi-empirical equations to complete the computation. Most of the property estimation equations are from“The Properties of Gases and Liquids”by R. C. Reid, J. M. Prausnitz and B. E. Poling. Alternatively, the well-known group contribution method and its modified counterpart group interaction contribution method are included.
The system has been tested in an IBM-compatible personal computer with PentiumIII-450MHz processor and 256MB RAM, running on Microsoft windows 2000 server operating system. Performance is excellent for both the property search and estimation. The system is stable and response is prompt.
