摘要
The 60 kt/a styrene unit at SINOPEC Qilu Branch Company was put on stream in 1988, with ethylbenzene and styrene manufactured respectively through high-temperature alkylation (the AlCl3 method) and adiabatic dehydrogenation under reduced pressure that were jointly developed by Monsanto/Lummus. AlCl3 method can cause corrosion and environmental problems, which would affect normal operation of the unit to pose a definite safety hazard.
