EXPERIMENT 5: RESIDENCE TIME IN A MIXED REACTOR

WebSep 26, 2014 · The abovementioned phenomena lead to a nonuniform residence time of the fluid elements in tubular reactors, which may have a detrimental effect on the reactor performance and product yield. In this chapter, residence time distribution (RTD) of ideal and nonideal reactors along with the method of determination are described in detail. WebJan 1, 2012 · Experimental method Measuring the average residence time is based on injecting a tracer at the entrance of the reactor and set the response to a pulse signal. The … WebThe residence-time distribution (RTD) of a reactor is a characteristic of the mixing that occurs in the chemical reactor. There is no axial mixing in a plug-flow reactor, and this omission is reflected in the RTD. The CSTR is thor- oughly mixed and possesses a far different kind of RTD than the plug-flow reactor. steven k and the bounty hunters
