Abstract:
The demethanizer tower of Kavian olefin plant had a problem in more than 77% of the nominal capacity. Its performance was reduced by flooding with considering the inside pressure drop and fluctuation of the bottom liquid level increase. For this reason, a study was performed and the simulation results (with PRO II and SULCOL) were successfully implemented. Finally, troubleshooting and practical solutions were compared with simulation results. In order to tower modifications, an instruction had been issued so that all 40 trays had to be completely discharged and then the tower was refilled with 16 ton packing. According to this solution, the volume of ethylene as final product was increases about 23% and reaches the designed nominal capacity.
