    • A multi-tubular reaction apparatus, a control system, and a method are provided for controlling temperature change of a heat medium in the reaction apparatus, and quickly adjusting fluctuation in temperature, to thereby properly control a reaction. In particular, the apparatus and system apply to a catalytic gas-phase oxidation reaction such as in producing (meth)acrylic acid or the like. The reaction apparatus includes a multi-tubular reactor having a plurality of reaction tubes in a shell in which a heat medium circulates, and a heat medium cooling apparatus outside the reactor. The reaction apparatus includes a process for primarily cooling the heat medium taken out outside the shell, a process for secondarily cooling a part of the primarily cooled heat medium, and a line for enabling the secondarily cooled heat medium and the primarily cooled heat medium, which is not secondarily cooled, to circulate in the shell.
    • 提供多管式反应装置,控制系统和方法,用于控制反应装置中的热介质的温度变化,并快速调节温度波动,从而适当地控制反应。 特别地,该装置和系统适用于催化气相氧化反应,例如生产(甲基)丙烯酸等。 该反应装置包括多管反应器,其中在热介质循环的外壳中具有多个反应管,以及在反应器外部的热介质冷却装置。 反应装置包括主要冷却从壳体外部取出的热介质的方法,用于二次冷却主要冷却的热介质的一部分的工艺,以及用于使二次冷却的热介质和主要冷却的热介质的管线, 不是二次冷却,在壳中循环。
