Abstract: The reasons for the short operating cycle of bottom reboiler and the high loss of C₄ components in bottom product of the debutanizer in the 800 kt/a ethylene plant at PetroChina Sichuan Petrochemical Company Limited during high-load production were analyzed, and the coking process was analyzed. The process parameters were optimized according to practical operation experience, and the goal of prolonging the operating cycle of reboiler was achieved. According to the process flow and the actual situation of reboiler on site, the main reasons for the shortening of operating cycle were found out, and some optimization measures were taken, thus ensuring the stable and efficient operation of ethylene plant and achieving the purposes of increasing plant capacity, reducing energy consumption and improving overall economic benefit.
