Steam Cracking - an overview ScienceDirect Topics

WebSteam cracking is a petrochemical process in which saturated hydrocarbons are broken down into smaller, often unsaturated, hydrocarbons. It is the principal industrial method for producing the lighter alkenes (or commonly olefins ), including ethene (or ethylene) and propene (or propylene ). WebFigure 1 A view of the steam crackers at Ludwigshafen in Germany. The whole site is the largest continuous chemical site in the world. The steam crackers alone occupy 64 000 m 2, which is about the size of 13 football fields. Naphtha is the feedstock and the main products are ethene and propene, used to make polymers. By kind permission of BASF. WebChemical cracking is the process of breaking down large molecules into smaller, more useful ones. It is a type of thermal decomposition reaction. The term cracking is most commonly used to describe the breakdown of long-chain hydrocarbon fractions from crude oil into shorter-chain alkanes and alkenes. docker apache servername
