Shell And Tube Tube Heat H eat Exchanger Exchanger Cost Estimation 21 June 2012 Posted by ankur2061 in Technical
As promised in my earlier blog entry "Cost Estimation Of i!ed oof #Cone$ Carbon %teel %torage Tan&s"' today(s blog entry relates to cost estimation of %)T heat e!changers* The e+uations are empirical and the reference is the same i*e*, "Estimate Costs of -eat E!changers E!chan gers and %torage Tan&s .ia Correlations" by Armando /* Corripio' atherine %* Chrien' and arence /* E.ans' Chemical Engineering maga3ine January 24' 1562* There is a bunch of e+uations and it too& some time to program it in e!cel but ultimately it as done* et us get don to the e+uations, Base Cost for CS loating!Head" #00 k$ag %100 &sig' exchanger S( )nits
