●  The project of 1.8 million tons/year methanol ,700 thousand tons /year coal to olefin , is the world’s first DMTO-II device .It won the first prize of National Technology Invention. The yield coefficient which compared with the DMTO-I is further improved .The methanol consumption per ton of olefin is reduced by 10%, the energy consumption is low, the production cost is greatly reduced, and the technology is in the international leading position.

●  Start-up  on May 10th of 2013 and completed on November 20th of 2014.It was successfully put into production on December 24th of 2014 .

●  More than 50% of the cryogenic valves supplied by Sanbora.
