Effect of Catalyst Reactor on Heat Exchanger Tubes

Effect of Reacting Catalyst Reactor on Heat Exchanger Tubes. After the catalyst was replaced by the whole catalyst, the content of catalyst in the new catalyst was larger, and in the initial stage of the catalyst, the catalyst contained more fine particles. When the catalyst is used for a period of time, when the amount of the fine particle catalyst is balanced with the amount of the added catalyst, the temperature of the cooler is increased, and the temperature of the cooler is increased. Blockage will slow down. A sudden increase in the concentration of catalyst particles in the reaction gas entering the chiller tubes during operation occurs mainly in the presence of catalyst run-off during operation of the device, or the reaction pressure is too low to degrade the separation efficiency of the cyclone, or Cyclone separation is better, and the reaction pressure control range is high. The height of the catalyst bed in the reactor rises gradually, the catalyst bed rises to a certain extent, the intermittent run-up of the fine particle catalyst in the upper part of the bed, and the intermittent increase of the catalyst particle concentration in the reaction gas entering the cooler. The shape and size of the cooler have an important influence on the clogging speed of the inner wall of the tube. The shape and size characteristics of the device directly influence the flow field distribution of the reaction gas flowing through the internal space of the equipment. If the size and design of the equipment Be reasonable. So that the reaction gas flow through the heat exchanger within the space distribution of the pressure drop and pressure drop distribution in the best range, it will delay the heat exchanger tube blockage play a very good role.
