Book Description
This report presents a cost analysis of para-Xylene production from mixed xylenes. The process examined is a xylene isomerization process with ethylbenzene (EB) isomerization. In this process, a mixture of C8 aromatics (mixed xylenes) containing xylene isomers and EB is sent to an adsorption unit for the recovery of p-Xylene. The remaining xylenes as well as the ethylbenzene are isomerized and the product from isomerization is recycled to the adsorption unit. This report was developed based essentially on the following reference(s): Keywords: Mixed Xylenes, C8 Aromatics, UOP, PAREX, Isomar, Axens, Eluxyl, ExxonMobil, Oparis, MHAI

Book Description
This report presents a cost analysis of para-Xylene production from mixed xylenes. The process examined is a xylene isomerization process with ethylbenzene (EB) dealkylation. In this process, a mixture of C8 aromatics containing xylene isomers and EB is sent to an adsorption unit for the recovery of p-Xylene. The p-Xylene-depleted stream is fed into the isomerization unit, where the remaining xylenes are isomerized to equilibrium and the EB is dealkylated to benzene by-product. This report was developed based essentially on the following reference(s): Keywords: Mixed Xylenes, C8 Aromatics, UOP, PAREX, Axens, Eluxyl, BP, AMSAC

Book Description
This report presents a cost analysis of meta-Xylene production from mixed xylenes. The process examined is similar to UOP's Sorbex technology. In this process, m-Xylene is recovered from a mixture of C8 aromatics via an adsorptive separation. The remaining xylenes stream, depleted of m-Xylene, is obtained as a by-product of the process. This report was developed based essentially on the following reference(s): Keywords: Mixed Xylenes, C8 Aromatics, UOP, MX Sorbex

Book Description
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

Book Description
This report presents a cost analysis of para-Xylene production from C9 aromatics. The process examined is a typical C9 transalkylation process. In this process, mixed xylenes and benzene are produced via transalkylation of toluene and C9 aromatics. The benzene is separated as by-product and p-Xylene is recovered from mixed xylenes via adsorption and isomerization steps. This report was developed based essentially on the following reference(s): Keywords: TDP, UOP, Tatoray, Axens, ExxonMobil, MTDP-3, Transalkylation, Disproportionation

Book Description
This report presents a cost analysis of para-Xylene production from toluene and C9 aromatics. The process examined is a typical toluene disproportionation and transalkylation process. In this process, mixed xylenes and benzene are produced via disproportionation of toluene and transalkylation of toluene and C9 aromatics. The benzene is separated as by-product. Finally, p-Xylene is recovered from mixed xylenes via adsorption and isomerization steps.

Book Description
This report presents a cost analysis of Dimethyl Terephthalate (DMT) from p-xylene and methanol The process examined is a typical oxidation followed by a methyl-esterification process. In this process, p-xylene is first oxidized. The product is then mixed with methanol and esterified. This report was developed based essentially on the following reference(s): Keywords: Dynamit-Witten-Nobel process, Xylene, Ethyl Alcohol

Book Description
This monograph consists of manuscripts submitted by invited speakers who participated in the symposium "Industrial Environmental Chemistry: Waste Minimization in Industrial Processes and Remediation of Hazardous Waste," held March 24-26, 1992, at Texas A&M University. This meeting was the tenth annual international symposium sponsored by the Texas A&M Industry-University Cooperative Chemistry Program (IUCCP). The program was developed by an academic-industrial steering committee consisting of the co-chairmen, Professors Donald T. Sawyer and Arthur E. Martell of the Texas A&M University Chemistry Department, and members appointed by the sponsoring companies: Bernie A. Allen, Jr., Dow Chemical USA; Kirk W. Brown, Texas A&M University; Abraham Clearfield, Texas A&M University; Greg Leyes, Monsanto Company; Jay Warner, Hoechst-Celanese Corporation; Paul M. Zakriski, BF Goodrich Company; and Emile A. Schweikert, Texas A&M University (IUCCP Coordinator). The subject of this conference reflects the interest that has developed in academic institutions and industry for technological solutions to environmental contamination by industrial wastes. Progress is most likely with strategies that minimize waste production from industrial processes. Clearly the key to the protection and preservation of the environment will be through R&D that optimizes chemical processes to minimize or eliminate waste streams. Eleven of the papers are directed to waste minimization. An additional ten papers discuss chemical and biological remediation strategies for hazardous wastes that contaminate soils, sludges, and water.

Book Description
The practice of biotechnology, though different in style, scale and substance in globalizing science for development involves all countries. Investment in biotechnology in the industrialised, the developing, and the least developed countries, is now amongst the widely accepted avenues being used for economie development. The simple utilization of kefir technology, the detoxification of injurious chemical pesticides e.g. parathion, the genetic tailoring of new crops, and the production of a first of a kind of biopharmaceuticals illustrate the global scope and content of biotechnology research endeavour and effort. In the developing and least developed nations, and in which the 9 most populous countries· are encountered, problems concerning management of the environment, food security, conservation of human health resources and capacity building are important factors that influence the path to sustainable development. Long-term use of biotechnology in the agricultural, food, energy and health sectors is expected to yield a windfall of economic, environmental and social benefits. Already the prototypes of new medicines and of prescription fruit vaccines are available. Gene based agriculture and medieine is increasingly being adopted and accepted. Emerging trends and practices are reflected in the designing of more efficient bioprocesses, and in new research in enzyme and fermentation technology, in the bioconversion of agro industrial residues into bio-utility products, in animal healthcare, and in the bioremediation and medical biotechnologies. Indeed, with each new day, new horizons in biotechnology beckon.
