| titleOfInvention | Process for producing cumene |
| abstract | In an alkylation zone (2), a benzene recycle stream (8) and a propylene feed stream (6) are reacted to convert the propylene and benzene into cumene (10). In a transalkylation zone (4), a polyisopropylbenzene stream (43) and a benzene recycle stream (20) are reacted to convert the polyisopropylbenzene and benzene into cumene (12). The effluents are passed into a dividing wall fractionation column (14). A cumene product stream (32) is removed from an intermediate point of the dividing wall fractionation column. A benzene recycle stream (18) is removed from a first end, and another benzene recycle stream (20) is removed from an intermediate point of the dividing wall fractionation column. A polyisopropylbenzene stream (34) is removed from a second end of the dividing wall fractionation column. The polyisopropylbenzene stream is passed to a polyisopropylbenzene fractionation column (40) to separate the polyisopropylbenzene (42, 43) from a heavy ends stream (44). |
