气分装置丙烯精馏塔改造? 45# marsmark this is a good design in principle, especially on the capacity increase. i do have concern on the efficiency claim due to the liquid recirculation or backmixing, which is the nature of vst type tray. since the mass transfer is proportinal to interfacial area x concentration driving force, this design may have better efficiency if the interfacial area increase outweights the driving force decrease due to intense mixing of vst. i believe this will be a very promising tray design if designed/applied carefully, especially for the foaming system.查看更多
