Intro to Plants
SM Plant
This plant uses benzene and ethylene as feedstock to ethyl benzene through alkylation, and dehydrogenates this ethyl benzene to produce styrene monomers.
-
- Ethyl Benzene Manufacturing Unit
- This unit consists of the reaction system that produces ethyl benzene and by products through the catalytic reaction between benzene and ethylene; the refining system that fractionates high-purity ethyl benzene from unresponsive ethylene, benzene and other by products and the regenerating system that regenerates the reactor catalyst.
-
- Styrene Monomer Manufacturing Unit
- This unit consists of the reaction system that passes the ethyl benzene, produced by the ethyl benzene manufacturing unit, through the fixed-bed catalytic layer, using high-temperature diluted steam for dehydrogenation, and the refining system that fractionates high-purity styrene monomer from crude styrene coming from the reactor (intermediate product).
Product uses
| Styrene Monomer (SM) | Used as interim feedstock for polymer synthesis products. Its main use is as the raw material for polystyrene (PS), acrylonitrile-butadiene-styrene (ABS), expandable polystyrene (EPS) and plastics. |
