ASPEN (Advanced System for Process Engineering) is a state of the art process simulator and economic evaluation package which was designed for use in engineering fossil energy conversion processes. ASPEN can represent multiphase streams including solids, and handle complex substances such as coal. The system can perform steady state material and energy balances, determine equipment size and cost, and carry out preliminary economic evaluations. It is supported by a comprehensive physical property system for computation of major properties such as enthalpy, entropy, free energy, molar volume, equilibrium ratio, fugacity coefficient, viscosity, thermal conductivity, and diffusion coefficient for specified phase conditions vapor, liquid, or solid. The properties may be computed for pure components, mixtures, or components in a mixture, as appropriate. The ASPEN Input Language is oriented towards process engineers.

• Resource Relation: Other Information: DN: Reduced minidisk storage can be utilized after installation of the IBM CMS version of ASPEN. The FORTRAN files occupy 36,160 blocks, or 44% of the space requirements, and the sample problems occupy 1780 blocks, or 2%. There are 2347 CMS files of which 1507 are of type FORTRAN. Three separate TAPE LOAD commands bring in the information to minidisks A, D, and E. The supplementary information can go to any minidisk. The space occupied by the A, D, E, and supplementary information is 12,476, 4536, 2263, and 62 blocks, respectively. The maximum block length is 4101. The IBM CMS version requires 5 cylinders minidisk (3350) storage and virtual machine size of 2.5 megabytes for each user account. The FORTRAN source and sample output files of...
