NewTianjin - Revamp of Benzene/Toluene splitter

The old Benzene/Toluene splitter of the Organic Synthesis Factory of Jilin Chemical Industrial Corp. was a valve tray column. The maximum capacity is 10m³/h. In Aug. 1997, it was revamped with JCPT tray by our Tianjin Corp. When the trays were changed in the revamping, only the old trays were replaced by Jet Coflow Packing Trays nothing else were changed. The support rings, downcomers, weirs, clearance under downcomer were remained as the same. After revamping, the column efficiency was increased and the capacity was increased to 14m3/h (for the pumps and other reasons, the upper operating limit not reached).

Feed composition:

Benzene	53~56%
Toluene	26~30%
xylene	14~21%
