Coking unit coke tower carrying coke powder problem conquered

December 23, 2022

A process technology for suppressing the coke powder carried to the bottom of the fractionation tower by adjusting the small blowing volume of the coke drum was successfully used in Maoming Petrochemical Coking Plant. This technology can effectively prevent the coke powder from being carried to the bottom of the fractionation tower when the coke drum is changed, ensuring the stable operation of the production system. The technology is easier to operate than the same type of technology, saving 3 tons of steam per hour and reducing economic losses by more than three million yuan.

With the continuous increase of the processing volume of inferior crude oil of Maoming Petrochemical, the coking coal content of the coking unit of the coking unit is getting higher and higher. In the process of tower operation, these coke powders are easily carried to the fractionation tower, causing safety production accidents. This is also a common problem faced by other domestic coking devices. In order to solve this problem, the company's technical personnel added defoamers, reduced the coke foam layer of the coke drums, and suppressed coke carryover. At the same time, the company formulated a pilot program for coking small blow steam process technologies, which was completed at the end of January. No. coking device trial.

The trial results showed that the process effectively suppressed the impact of the coke drum coke powder being carried to the bottom of the fractionation tower. At present, the technology has been formally put into use by two sets of coking units at Maoming Petrochemical.
