ABSTRACT:
The invention focuses on distributing the vapor/liquid flow that emerges from an inlet nozzle across the tube sheet of an alkylation reactor or heat exchanger. The flow distributor takes the two-phase flow that emerges from the inlet nozzle, turns it towards the tubesheet and delivers a uniform mixture across the tube sheet. The flow distributor is located in the channel head of the reactor or heat exchanger. In order to dislodge the liquid film from the wall of the inlet nozzle, trip rings and angular trip tabs are located internally in the flow distributor.
