Engineering design achievements

The technical team has designed more than 5000 columns which cover various chemical units of domestic major petrochemical enterprises, such as Sinopec, PetroChina, CNOOC, Shenhua Group, etc. The main contains:

Column internals design of propane dehydrogenation unit

The technical team completed the Design achievements of PDH unit

The analysis results of the 1st phase project 1.2 Mt/a propane dehydrogenation to high-performance polypropylene unit showed that：the propylene content at the top of the tower is more than 99.7%, and the propylene content of the bottom of the tower is generally 0.45%. The separation effect of the PDH device is the best at home and abroad.
