Ethylene

Abstract

In this comprehensive discussion of the production and uses of ethylene, the topics covered include the properties of ethylene, industrial production, storage, shipping, handling, and economics. Extensive coverage of the commercial production via thermal cracking is detailed.This reaction is discussed as well as the methods employed to predict the feedstock conversion. Product distributions are given for a variety of feedstocks. A description of the industrial furnaces available is given as well as description and process flow diagrams. Information is provided on coke deposition during the cracking process, giving the methods used to inhibit coke production and methods used to remove coke deposited, Ethylene is the largest volume building block for many petrochemicals. Although ethylene is a colorless gas with a mild odor that is not irritating to the eyes or respiratory system, it is considered a mild asphyxiant.

Ethane/ethylene separation on a copper benzene-1,3,5-tricarboxylate MOF

“…Low molecular weight olefins, such as ethylene are an important feed stock used not only as a raw material in polymer production but also as a starting material/intermediate for the synthesis of several compounds in many industrial processes [1]. Ethylene, like all alkenes, has the ability to react with itself as monomers to form long polymeric hydrocarbon chains.…”

“…The ethylene polymerization leads to the formation of the polyethylene that accounts approximately for 60% of the total use of ethylene [1]. This alkene can also be used in the production of vinyl acetate by oxidation when combined with acetic acid, as well as in the manufacture of vinyl alcohol when combined with water.…”

“…This alkene can also be used in the production of vinyl acetate by oxidation when combined with acetic acid, as well as in the manufacture of vinyl alcohol when combined with water. Furthermore, vinyl dichloride and ethylene oxide are obtained from ethylene by chlorination / dehydrochlorination and oxidation processes, respectively and are important intermediates in the polyvinyl chloride (PVC) and ethylene glycol production [1].…”

“…Depending on its final application, ethylene can be obtained in different grades. For example, a high purity grade (> 99.5%) is required in the polymer production, since the impurities lead to the formation of undesirable products, which affect the characteristics of the final polymer [1].…”

Alternatives to Cryogenic Distillation: Advanced Porous Materials in Adsorptive Light Olefin/Paraffin Separations

“…[61b] In addition to type-A and faujasite zeolites, microporous titanosilicates are another class of microporous inorganic materials that show promising potential for olefin/paraffin separations ( Figure 5). [62] Different from common zeolites that have AlO 4 and SiO 4 as primary building blocks, titanosilicates are interconnected by SiO 4 tetrahedra and TiO 6 octahedra. For instance, Engelhard Titanosilicate-10 (ETS-10), a member of the titanosilicate family, possesses two perpendicular TiO 6 linear chains in the x-y plane.…”
