http://websites.umich.edu/~elements/fogler&gurmen/html/course/lectures/two/index.htm WebIt can be demonstrated that an infinite number of infinitely small CSTRs operating in series would be equivalent to a PFR. The behavior of a CSTR is often approximated or modeled by that of a Continuous Ideally Stirred-Tank Reactor (CISTR). All calculations performed with CISTRs assume perfect mixing. If the residence time is 5-10 times the ...
WebThe streams are mixed immediately before entering. Two reactors are available. One is a gray, 200.0-dm CSTR that can be heated to 77°C or cooled to o®C, and the other is a white, 800.0-dm PFR operated at 300 K that cannot be heated or cooled but can be painted red or … WebCSTR in Series 2010 - Michigan State University
