一、概述塞阀是同轴催化裂化装置十分重要的自动控制设备。塞阀分为待生塞阀(控制从汽提段进入再生器的待生催化剂量)和再生塞阀(控制从再生器进入提升管反应器中的再生催化剂量)。在正常操作时,两阀用来调节待生和再生催化剂的循环量,并控制汽提 First, an overview Plug valve is a coaxial catalytic cracking unit is very important automatic control equipment. Plug valves are divided into peed-plug valves that control the amount of spent catalyst entering the regenerator from the stripping section and a regenerative plug valve that controls the amount of regenerated catalyst entering the riser reactor from the regenerator. In normal operation, the two valves are used to adjust the amount of catalyst to be regenerated and regenerated and to control the stripping
