Hydrocarbon Engineering,
GTC Technology (GTC) has supplied its advanced distillation technology for a new mixed xylenes recovery unit for TonenGeneral Sekiyu K. K. (TonenGeneral). The grassroots unit is located at TonenGeneral’s refinery in Ichihara City, Chiba Prefecture, Japan, and successfully started up in April 2016.
The xylene unit has capacity for 230 000 tpy. Unique to this design is high purity toluene as well as high purity C9 aromatics being produced out of the same column with the xylenes. The unit uses GTC’s Dividing Wall Column (GT-DWC?) technology for high energy efficiency. This installation also uses a first of its kind design for divided wall columns (DWCs) with the overhead vapours providing the heating duty to two upstream units.
GTC provided a single source responsibility for process license, basic engineering design, equipment supply and process guarantees.
