  • Understanding Naphtha and Ethane Cracking Processes
    In the petrochemical industry, two of the main feedstocks for steam crackers are naphtha and ethane Naphtha is primarily derived from crude oil, while ethane is more prevalent in natural gas and natural gas liquids (aka NGLs, a mixture of various hydrocarbons often co-produced along with natural gas) Steam cracking these hydrocarbons is
  • Steam cracking - Wikipedia
    Steam 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)
  • Question 25: What issues are encountered when introducing cracked . . .
    Adding cracked naphtha to a reformer pre-treat unit designed for straight-run naphtha will result in higher hydrogen consumption and increased temperature rises Often units that previously saw no rise or a temperature loss across the hydrotreating reactor will see a much bigger exotherm
  • Naphtha Steam Cracking (NSC) unit optimization - ABB
    aromatic naphtha at the same severity would severely reduce furnace run-lengths by excessive coking The steam-cracking process involves multiple stages including, mainly, the cracking furnace, quench, downstream compression, and recovery purification The feed to the cracking furnace is pre-heated and mixed with steam at a controlled
  • Direct prediction of steam cracking products from naphtha bulk . . .
    Steam cracking of naphtha is an important chemical process for olefins production Naphtha cracking furnace is the core device of this process, where hydrocarbons undergo highly complex cracking reactions through the free radical mechanism to produce olefin products
  • ETHYLENE PRODUCTION FROM NAPHTHA (HIGH SEVERITY STEAM CRACKING)
    production from light naphtha feedstock The process examined is a typical steam cracking process In this process, naphtha is thermally cracked in pyrolysis furnaces at high severity conditions to maximize Ethylene yield In addition to Ethylene, the process also generates polymer grade propylene, pygas and a mixed C4s stream as by-products
  • Naphtha Catalytic Cracking in FCC Units Past Present - Refining Community
    Naphtha Catalytic Cracking in FCC Units • p-Naphtha Supply Sources are Available Both Domestically Globally • Crack it! Requires Higher Severities, Rx Temp, C O, Increase Residence Time, Bed Cracking • Minimize 450°F+ Content with the Naphtha Feed in the Reaction Zone (Segregate from Heavy Feed )
  • Naphtha
