Pygas Hydrotreatment

GTC Technology, in alliance with technology partners, offers an optimized technology for two-stage pyrolysis gasoline hydrotreatment. The technology is simple and easy to implement into existing plant requirements. The process is applied to the C₅+ fraction of raw pyrolysis gasoline.

Advantages:

Flexibility in prefractionator cut point and a proprietary vaporizer allows control of polymerization potential in the hydrotreaters
Reactor operates at high liquid content with mixed phases to minimize polymer byproduct plugging
Optimized recycle scheme minimizes hydrocarbon vaporization and thereby extends reactor run length
Catalyst exhibits high activity, stability, mechanical strength, and poison resistance
Aromatics saturation in second stage reactor is less than 1%
