Dynamic Simulation and Start-up Scenario a Pilot Distillation Column for Separating C6-C8 Hydrocarbons

摘要: A pilot distillation column was fabricated for multipurpose functions, such as separation testing compared with a real plant column, and sample preparation other projects. The packing efficiency of this developed by changing the material. Packing is normally an important key index, especially after revamp. Aspen Dynamic used to generate best procedure start-up operation, covering three variables: distillate rate, reflux rate bottom rate. according these parameters divided into six scenarios. In addition, effect feed location operating conditions, including temperature profile benzene concentration in overhead stream, liquid levels drum sump. test run data matched well, 0.6 Murphree efficiency. optimal operation found be – scenario, which took just 9 h reach steady state.
