STUDY ON A FUEL-TYPE VACUUM TOWER SIMULATION CALCULATION Ⅱ. ABSORPTION-TYPE ALGORITHM OF MODEL SOLUTION

Zheng Ling Du Yingsheng Yu Guocong (Chemical Engineering Research Center, Tianjin University, Tianjin 300072)  
An absorption-type algorithm (ATA) for solving mathematical model of fuel-type vacuum tower is proposed. The drying-operating vacuum tower is considered as a series of an adiabatic flashing process combined with several absorption process, while the wet-operating vacuum tower as a series of a stripping process combined with several absorption process, and each absorption process is calculated by SR method. Compared with the conventional distillation-type algorithm (DTA), this method has the advantage of converging quickly from a few initial estimates that are not necessarily accurate. The need of internal storage for this method is small, and can be operated in microcomputer. The calculated results is in agreement with the actual process.
