Material Balances Project Styrene Manufacture

Styrene Manufacture This project is to evaluate the economics for a process to manufacture styrene by dehydrogenating ethyl benzene. The pertinent reactions are shown below. Information on reaction equilibrium constants, selectivity, selling prices for reactants and products, and a rough flow sheet are included on the following pages. Styrene is produced by the reaction


Apr 12, 2017 · ETHYLBENZENE MARKET IN WORLD •Styrene production is the largest application accounting for 99% of global EB demand; 1% of global EB output is used as an intermediate in stone production. •China and USA – each consumes the same amount of EB as all Western European countries do (shares are approximately 13%).

Design Project Styrene Production Process Description Figure 1 is a preliminary process flow diagram (PFD) for the styrene production process evaluated in the Fall semester 1999 in ChE 40. In this process, styrene is manufactured by the dehydrogenation of ethylbenzene in Unit 500. The reaction is endothermic, reversible, and limited by equilibrium.

Oct 14, 2010 · A recent stone by Vasudevan et al. (Ind. Eng. Chem. Res. 2009, 48, 10941−10961) presented a flowsheet of the styrene process, which has several interesting design and control features. Their study concentrated on a comparison of three plantwide control methodologies. The economic optimum design of the process was given, but no quantitative details were given of how the optimum …

New Process for Producing Styrene Cuts Costs, Saves Energy ...

Global production of styrene in 2010 was 25 million metric tons (27.5 million U.S. tons), of which approximately 4 million metric tons (4.4 million U.S. tons) originated in the U.S.

0708 4 abs Styrene

Snamprogetti S.p.A. and Dow are jointly developing a process for the production of styrene monomer from ethane and benzene. Ethane, along with ethylbenzene from the alkylation unit, is fed to a dehydrogenation reactor with a catalyst capable of simultaneously producing styrene and

Jul 22, 2015 · The styrene plant is in production for 300 days a year, 24 hours a day. The plant produces 215 million pounds of styrene/yr and 90% of the total styrene is considered high purity and is 99.8% pure, while the remaining 10% of styrene produced is considered low purity and is 98% pure.


In the polystyrene production unit, the raw material is styrene produced in Unit 500. Although Unit 500 might not be profitable, the savings by producing styrene rather than purchasing from an independent supplier can significantly reduce raw

Simulation to Production of Styrene by Catalytic ...

Nearly 90% of styrene production utilizes dehydrogenation, mainly because of its simplicity and cost-effectiveness.[1] The styrene process was developed in the 1930s by BASF (Germany) and Dow stone (USA). Over 25×106 tons/year of styrene monomer is produced worldwide [2]. The

Styrene - General, Production Process, Patent, Company ...

Styrene is produced by the dehydrogenation of ethylbenzene. Ethylbenzene is formed by reacting ethylene and benzene, and most benzene is made by hydrodealkylation of toluene, which is obtained as a byproduct of gasoline manufacture. Most ethylbenzene manufacturers convert it directly into styrene.

Styrene - Wikipedia

Styrene plays an important role in stone production to make latex, synthetic rubber, and other polystyrene resins. A common way to produce styrene is through the dehydrogenation of ethylbenzene . Benzene and ethylene are first compressed and sent to a reactor to produce ethylbenzene in the presence of a Friedel–Crafts catalyst ( aluminum chloride ) at approximately 95 °C.
