a kind of optimal extraction agent is determined for extraction distillation of propane-propene process, based on the simulation results by the aspen plus software.
the critical point in the experiment lies in the selection of extraction agent and manipulating process.
实验的操作要点在于萃取剂的选用及萃取的过程。
in this paper, the group separation of rare-earth element is studied by the method of solid extraction with p507 as extraction agent and paraffin as solvent.
