Modern Petrochemical Technology

A text that explores the essence of petrochemicals and petrochemical technology

Modern Petrochemical Technology: Methods, Manufacturing and Applications is a comprehensive resource that provides an overview of the uses for common petrochemical building blocks, a review of the marketplaces, and offers a survey of the technology used to make the key petrochemical building blocks. The book contains both critical information the technologies used to produce petrochemicals, how the various petrochemicals are applied in industry, and provides illustrative examples and problems designed to reinforce the learning about the basic science, engineering, and use of petrochemicals.

The book explores three seprate petrochemical building block - olefin complexes, aromatic complexes and synthesis gas complexes - and examines the “interconnected” nature of these building blocks. The authors also include information on the olefins productions using steam cracking, paraffin dehydrogenation, and methanol to olefins technologies and describes various methods, commercial processes to produce aromatics such as benzene, toluene and xylene, and much more. This important book:- Offers a guide to the critical information on petrochemical producing technologies- Includes material on various petrochemicals from the industrial point-of-view- Explores the separation processes, membrane technology, absorption technology, liquid-liquid extraction, and more- Contains material from a team of noted experts- Provides a survey of examples of commercialization applications of petrochemicals

Written for chemical engineers, chemists in industry, membrane scientists, and process engineers, Modern Petrochemical Technology provides an overview of markets and uses for common petrochemical building blocks as well as includes a survey of the technology used to make the key petrochemical building blocks.
