Prilling Tower Inner Side Epoxy Work - KFL, Shahjahanpur

摘要

Prilling tower in urea plant was constructed in the year 1994. Epoxy coating was provided to inner side of the prilling tower to protect it against urea. It was taken into operation on 23rd November 1995. Since then, it has been producing urea in the form of prills. On inspection, it was found that the epoxy coating inside of prilling tower was eroded or peeled off at few places which could result in seepage of urea to the RCC structure and weaken the tower. So it was decided to take proper action to get it rectified by providing epoxy coating on the inner surface during the annual turnaround 2017-18. It took 20 days to complete the job. The article describes the experience of epoxy coating on the entire area of prilling tower (about 9000 m~2) without any incident.
