steam heating chemical stainless steel reactor
An apparatus used in carrying out chemical reactions. The design and operation of chemical reactors are dictated by thestate of aggregation of the interacting substances and by the conditions (temperature, pressure, reactant concentrations)required to ensure the desired reaction rate and direction. According to the first criterion, a distinction is made betweenchemical reactors designed for reactions in homogeneous system (single-phase gaseous or liquid) and reactors used forheterogeneous systems (multiphase, for example, gaseous-liquid-solid). The second criterion is used to classify reactors aslow-, medium-, or high-pressure; low- or high-temperature; and batchwise, semicontinuous, or continuous-operation.
