Work is progressing on two GTC projects in China.  For Hengli (Dalian) Refinery and Petrochemical Co., GTC is providing two aromatics extraction units using GT-BTX®.  The two units will be the largest of their kind in the world, with a combined capacity of 3MMTA of benzene, toluene and xylenes.

For DongYing YaTong Petrochemical Co., Ltd. of China, GTC is installing a 550kta GT-BTX® aromatics extraction/ separation unit. The installation is the first GT-DWC® application in China for aromatics separation.

The projects are a collaborative effort between four GTC offices: Beijing and Houston (licensing), and Beijing, Non-san and Euless (tower internals design and manufacturing).

RongRong Zhang, Senior Process Engineer/GTC Beijing, is the Installation Supervisor with support from Renwei ‘Rain’ Wang, Engineer/GTC Beijing.


At the Hengli plant above, GTC’s GT-BTX process is being installed in two units (1.5MMTA each). These will be the world’s largest aromatics extraction units.

For DongYing YaTong Petrochemical Co., GTC is providing the technology for a solvent recovery column (SRC), dividing wall column (DWC), and extraction distillation column (EDC).
