    • Techniques are provided for operating a reactor during a catalyst transition period. The instantaneous reaction rate during a catalyst transition period can be determined using real-time measured process variables, and material balance calculations to provide an instantaneous reaction rate in approximately real time. According to certain embodiments, a material balance can be performed on the reactor system using a continuous ideal stirred tank reactor to determine the fractions of each type of catalyst that are present in the reactor, as well as the overall weight percent of catalyst in the reactor. A controller can then calculate the overall instantaneous reaction rate based on the respective catalyst fractions and the overall weight percent of catalyst in the reactor. The catalyst feed rate can then be adjusted based on the determined instantaneous reaction rate to maintain the instantaneous reaction rate within desired limits during a catalyst transition period.
    • 提供了在催化剂过渡期间操作反应器的技术。 可以使用实时测量的过程变量和材料平衡计算来确定催化剂过渡期间的瞬时反应速率,以大致实时提供瞬时反应速率。 根据某些实施方案,可以使用连续理想的搅拌釜反应器在反应器系统上进行物料平衡,以确定存在于反应器中的每种类型的催化剂的馏分以及反应器中催化剂的总重量百分数 。 然后,控制器可以基于各个催化剂组分和反应器中催化剂的总重量百分数来计算总瞬时反应速率。 然后可以基于确定的瞬时反应速率来调节催化剂进料速率,以在催化剂过渡期间将瞬时反应速率保持在所需限度内。
