FCC Heat Balance– Catalyst circulation rate can be calculated by heatbalance and directly influences Rg temp.» Cat/Oil = Cat circulation rate (T/hr)/Feed Rate (T/hr)» Del coke = (CSC – CRC) = Coke yield / C/O
FCC Heat BalanceDelta Coke is decreased by– Increased Cat / Oil ratio» By increasing Rx temp» By reducing combined feed temperature– Improved feed nozzle dispersion– Better stripping– Improved feed quality» Higher API, K factor» Lower CCR, boiling range
