Residence time distribution - Wikipedia, the free encyclopedia
The residence time distribution (RTD) of a chemical reactor is a probability distribution . can be found from the mass balance: . ideal reactor models: the plug-flow reactor and the continuous stirred-tank reactor (CSTR), or mixed-flow reactor.
