Propylene Production Methods And FCC Process Rules In Propylene Demands

The market for propylene as a basic intermediate petrochemical continue to grow at average rates of 4-5% per year. the largest source of propylene supply to the petrochemical markets is steam crackers (as a by product of ethylene) the second largest source of propylene supply to petrochemical markets is refinery FCC units (as a by product of gasoline and distillates). However the FCC unit is becoming increasingly important as a source of propylene supply to meet future demand growth into the world petrochemical markets. Ethylene growth rates have lagged propylene growth rates and will continue to do so in the future .similarly the growth rate of transportation fuels is several times lower than propylene. currently steam cracking and refinery operations constitute over 97% of the propylene produced today. clearly alternative routes to propylene will gain prominence as producers seek to leverage their existing assets and available internal streams to find an optimum solution for meeting the demand for propylene . The process according FCC technology can be a solution to meeting the propylene gap in the future. In this manuscript the propylene method production and comparisons of them with each other will be reviewed.
