Causes analysis and optimization measures of tube bundle coking in C5 removal tower reboiler of methyl ethyl ketone unit
The causes of tube bundle coking in C5 removal tower reboiler Ⅰ of methyl ethyl ketone unit of Lanzhou Petrochemical Company,PetroChina,were analyzed,and the corresponding optimization measures were proposed.The results showed that main cause of tube bundle coking of reboiler Ⅰ was the olefin in C5 raw materials and hot spot of the re-boiler Ⅰ.The heating load of the reboiler Ⅰ could be reduced from 9 470.842 MJ/h to 5 812.549 MJ/h by increasing the liquid level of C5 removal tower,re-ducing the heating load of the reboiler Ⅰ and opti-mizing the heat of C5 removal tower.
