Abstract: A polymer can be prepared using a loop reactor and process including feeding a process stream through the loop reactor and maintaining the loop reactor at a steady state by controlling a flow of coolant fluid to maintain a temperature in the loop reactor at a preset point. The temperature in the loop reactor may be maintained at a preset point by using a coolant fluid flow controller and valve unit having a substantially linear response over the normal operating range of the controller and valve unit. The normal operating range of the controller and valve unit may be sufficient to provide a flow range not limiting to the throughput of the loop reactor.

Abstract: A fuel conversion reactor includes a shell-and-tube heat exchanger for controlling the temperature of a hot gaseous mixture produced by catalytic or non-catalytic reaction of a fuel with a gaseous fluid, and for controlling the temperature of the gaseous fluid and/or the fuel prior to the reaction. The reactor is either a catalytic or non-catalytic burner, or a fuel reformer for converting a fuel to hydrogen. A preferred reactor includes an outer shell having first and second ends and an inner surface, a primary inner shell extending into the outer shell, the primary inner shell defining a heat exchanging chamber and having primary and secondary ends, and a secondary inner shell having a first end located adjacent the secondary end of the primary inner shell. One or more outlet apertures are formed between the two inner shells for passage of the gaseous fluid out of the heat exchanging chamber. There are also a plurality of heat exchange tubes extending through the heat exchanging chamber between first and second tube sheets and connected to same. The first tube sheet is mounted in the primary inner shell while the second tube sheet is connected to the secondary inner shell. The tubes form passages for flow of the hot gaseous mixture in heat exchange contact with the gaseous fluid through the heat exchanging chamber, thereby preheating the gaseous fluid prior to reaction with the fuel. The adjacent ends of the inner shells form a disconnected joint and the secondary inner shell is free to move relative to the primary inner shell upon thermal expansion of the tubes.

Abstract: In the reaction of catalytic gas phase oxidation by means of a shell-and-tube type reactor adapted to circulate a heating medium to the shell of the reactor through the medium of a circulation device connecting an annular conduit connected thereto, a method for the catalytic gas phase oxidation characterized by subjecting a part of the heating medium extracted from the shell of the reactor to heat exchange, introducing the heating medium resulting from the heat exchange into the proximity of a heating medium circulation inlet on the inlet side of the circulation device or the annular conduit on the outlet side of the reactor. The flow rate of the heating medium after the heat exchange is preferred to be in the range of 2-40 vol. % based on the flow rate of the heating medium within the shell of the reactor and the temperature difference of the heating medium at the inlet and the outlet to be in the range of 15-150° C. According to this invention, it is made possible to reduce evenly the hot spots in the reaction tubes, improve the yield of the product aimed at, and implement a reaction of catalytic gas phase oxidation of propylene or isobutylene.

Abstract translation: 在通过壳管式反应器进行催化气相氧化的反应中，该反应器适于通过连接连接其的环形导管的循环装置的介质将加热介质循环到反应器的壳体，催化剂的方法 气相氧化特征在于使从反应器壳体中提取的一部分加热介质进行热交换，将由热交换产生的加热介质引入循环装置入口侧的加热介质循环入口附近，或 反应器出口侧的环形导管。 热交换后的加热介质的流量优选为2-40体积％。 基于反应器壳体内的加热介质的流量，入口和出口处的加热介质的温度差在15-150℃的范围内。根据本发明，制成 可能均匀地减少反应管中的热点，提高目标产品的产率，并实现丙烯或异丁烯的催化气相氧化反应。
