Abstract:

The sulfolane extraction distillation (SED) process is widely applied to separate aromatics and non-aromatics, but it is difficult to build a model for SED because of unknown binary interaction parameters (BIPs). In this study, liquid-liquid equilibrium data are used to regress unknown BIPs, and other unknown BIPs are calculated based on standard solution theory, and then a process model for RIPPs SED is developed. The gap between model results and RIPPs patent is marginal. It is shown that properties method used and process model built in this paper could calculate the SED process correctly and provide theoretical and technical support to the actual production processes.
