Naphtha steam cracking process pdf
WitrynaNaphtha cut and is the most desirable cut for injecting into a steam cracker to produce renewable recycled circular monomers such as ethylene and propylene to produce polyethylene and polypropylene, respectively. The 400°C cut is the medium cut and can be injected into some steam crackers that can accept a heavier feed to produce WitrynaSteam cracking is a petrochemical process in which saturated hydrocarbons are broken down into smaller, often unsaturated, hydrocarbons. It is the principal industrial …
