This report presents the economics of Styrene production from ethane and benzene in the United States, with pure hydrogen as by-product. In this report, ethylbenzene (EB) is first generated from benzene and recycled ethylene. Then, fresh ethane and the EB are dehydrogenated to form ethylene and Styrene. The process analyzed is based on concepts proposed in patents issued to Dow and Snamprogetti.
This study presents the costs associated with Styrene production in the United States. In this report, ethylbenzene (EB) is first generated from benzene and recycled ethylene. Then, fresh ethane and the EB are dehydrogenated to form ethylene and Styrene. The hydrogen produced is valued as fuel. The process analyzed is based on concepts proposed in patents issued to Dow and Snamprogetti.
This report examines the costs related to Styrene production from ethylbenzene in the United States, via a typical adiabatic dehydrogenation process.
This report analyzes the economics of an integrated plant producing Styrene from benzene and ethylene located in the United States. The following processes are encompassed: (1) alkylation for ethylbenzene production from benzene and ethylene; and (2) catalytic dehydrogenation process for Styrene production from ethylbenzene.
This report analyses the economics of Styrene production from methanol and toluene in the United States. The process evaluated is similar to Exelus Styrene Monomer Technology (ExSyM) technology. In this process, toluene is submitted to alkylation with methanol over zeolite catalyst, yielding styrene.
This report assesses the economics of Styrene production from polystyrene waste via pyrolysis in the United States. In this process, polystyrene waste is submitted to pyrolysis in a fluidized bed reactor. The pyrolysis gas is then sent to a distillation section where styrene is recovered along with toluene and fuel oil.
This study presents the economics of Styrene production from chemical grade (CG) propylene and ethylbenzene in the United States. The process examined is a Propylene Oxide/Styrene Monomer (POSM) technology similar to the one owned by LyondellBasell. This process involves ethylbenzene oxidation, epoxidation, hydrogenation and dehydration steps.
