【Abstract】 Abstract For the application of HTFS (heat transfer and fluid flow service) program in chemical process design, the Peng-Robins ion equation of state and Soave-Redlich-Kwong equation of state, both modified for adaption to high hydrogen-containing systems during recent years, and mathematics models for heat transfer properties were investigation. The results of calculation were compared with both experimental data and calculated data by Aspen-Plus program. Some of them were selected for the use in high hydrogen-containing systems. This physical property calculating system was used in combination with the operation data of a vertical tube-shell exchanger in a reformer to investigate the calculation of heat transfer and pressure drop by TASC2 (tube-shell exchanger design and performance program with condensing, single-phase and boiling options) program of HTFS. The results are satisfactory.更多还原
