The purpose of U5000 is to separate aromatics from non-aromatics by extracting benzene and toluene from raffinate by means of the solvent N-Formylmorpholine (NFM). Its feed is light reformate coming from reformate splitter (C-A3001). Morphylane has a design capacity of 86 m3/hr.
Overhead stream (C7-) of Raffinate splitter is heated and then it enters the extractive distillation column (C-A5001) to separate benzene and toluene from non aromatics. The aromatics are recovered by means of the solvent NFM. The vapor pressures are changed by adding NFM in such a way that non-aromatics can be removed by distillation from benzene and toluene as overhead product (raffinate) which sent to storage tanks. Rich solvent enters stripper column (C-A5002) and
