Description of products
Reactor to realize the reaction process of equipment, widely used in chemical industry, oil refining, metallurgy, light industry and other industries. Chemical reaction engineering in industrial reactor for reaction process as the research object, using the mathematical model method to establish mathematical model reactor, the reactor process on the effect of chemical reaction and the reactor and dynamic characteristics of the reactor parameters sensitivity, in order to achieve reliable industrial reactor design and operation control.
Heat transfer way
Most reactions have obvious heat effect. For the reaction under the appropriate conditions of temperature, often requires heat exchange of reactant system. Heat transfer means has indirectly in heat and heat transfer directly. Indirect heat exchange reaction material and heating medium heat transfer through the partition, direct heat transfer materials and heating medium to direct contact heat exchange. Of exothermic reaction, reaction products can be used carrying heat of reaction to the heating reaction raw materials, to achieve the required temperature, the reactor is called the heat from the reactor.
According to the condition of heat transfer in the process of reaction, the reactor can be divided into:
(1) isothermal reactor reactant is an ideal reactor temperature equal everywhere. Reaction heat effect, or reaction materials and sufficient heat transfer between heating medium, or reactor heat feedback greatly, such as severe stirred tank reactor) reactor, which can approximate isothermal reactor.
(2) the adiabatic reactor reaction zone and the environment of a kind of ideal reactor without heat exchange. Response of the large industrial reactor of the heat exchange device, so the heat exchange with the outside world can ignore, can be regarded as adiabatic reactor.
(3) non isothermal non adiabatic reactor with heat exchange with the outside world, the reactor thermal feedback, but short of isothermal condition of the reactor, such as column tubular fixed bed reactor.
Heat transfer in the reaction zone, such as heat transfer through the jacketed stirred tank, also can be in range of reaction, such as level of heat exchange between multistage reactor.
