An injection rate of 15μg/g CDF-10 antifoaming agent was normally injected to the top of the coke drum at the final 2-6 h of the coking cycle. It could eliminate 3m foam and increase the effective utilization ratio of the coke drum from 65%to 78%, and resulted in higher throughput. The said antifoaming agent had no poison effect on hydrogenation catalyst.
