This report presents a cost analysis of Benzene production from pyrolysis gasoline (pygas). The process examined is a typical hydrodealkylation process, also called bulk dealkylation process. First pygas is fractionated into 3 hydrocarbon cuts, a C5s stream and a heavies stream are generated as by-products. The remaining C6-C8 fraction is then directed to the hydrodealkylation step, in which the aromatics content in the process stream are converted into benzene This report was developed based essentially on the following reference(s): "Benzene", Ullmann's Encyclopedia of Industrial Chemistry, 7th edition Keywords: Aromatics, BTX, Diprolene, Toluene, Xylene, Houdry Pyrotol, Mitsubishi MHC, Bulk Dealkylation, CB&I Lummus

This report presents a cost analysis of para-Xylene production from mixed xylenes with o-xylene co-production. The process examined is a xylene isomerization process with ethylbenzene (EB) isomerization. In this process, p-Xylene is recovered from a mixture of C8 aromatics via an adsorption unit. The remaining xylenes as well as the ethylbenzene are isomerized and the product from isomerization is recycled to the adsorption unit. Part of the o-xylene is also recovered as by-product. This report was developed based essentially on the following reference(s): (1) US Patent 7301064, issued to UOP in 2007 (2) US Patent 3997620, issued to UOP in 1976 Keywords: Mixed Xylenes, C8 Aromatics, UOP, PAREX, Isomar, Axens, Eluxyl, ExxonMobil, Oparis, MHAI

This report presents a cost analysis of Benzene production from pyrolysis gasoline (pygas) The process examined is a typical extractive distillation process. First pygas is fractionated into 3 hydrocarbon cuts, a C5s stream and a heavies stream are generated as by-products. The remaining C6s fraction is then fed to an extractive distillation system to recover benzene. This report was developed based essentially on the following reference(s): "Benzene", Ullmann's Encyclopedia of Industrial Chemistry, 7th edition Keywords: BTX, Aromatics, Hydrotreatment, Diprolene, Distapex, Lurgi, ED

This report presents a cost analysis of Benzene production from toluene. The process examined is a typical selective toluene disproportionation process (STDP). In the STDP, toluene is converted into benzene and xylenes (mainly, p-xylene). Benzene is recovered from the reactor output via distillation and p-Xylene is separated as a by-product using a crystallization unit. This report was developed based essentially on the following reference(s): (1) US Patent 7230152, issued to UOP in 2007 (2) US Patent 4097543, issued to ExxonMobil in 1978 Keywords: Aromatics, BTX, ExxonMobil PxMax, UOP Px Plus, GTC GT-STDP

This report presents a cost analysis of Nitrobenzene production from benzene and nitric acid. The process examined is similar to Chematur's adiabatic benzene nitration process. In this process, benzene, nitric acid, and sulfuric acid are reacted in a tubular nitrator. The product from nitration is washed and purified, producing technical-grade Nitrobenzene. This report was developed based essentially on the following reference(s): Keywords: Chematur, Benzene Nitration
