How design of fin-and-tube heat exchanger hello, how can we design a fin-and-tube heat exchanger heat exchangers share can you help by adding an answer answer add your answer. As with any heat exchanger type, there are several important design factors to consider when designing a plate-and-frame heat exchanger these factors include temperature approach, pressure drop, number of passes, channel velocity, plate gap, and plate thickness, and corrugation arrangement. A regenerative heat exchanger (regenerator), is a type of heat exchanger where the flow is cyclical and periodically changes direction it is similar to a countercurrent heat exchangers however, a regenerator mixes the two fluid flows while a countercurrent exchanger maintains them separated. A design procedure for the main heat exchanger is summarized in figure 1 specified temperature difference in the warm end of the heat exchanger and an object function for the optimization2 the specification contains process parameters for the inlet natural gas stream and the outlet lng product. Introduction to thermo-fluids systems design published online: 30 aug 2012 summary.
L with a thermal conduction technology featuring forced convection, this heat exchanger can raise heat transfer efficiency by 20~30% via shorter path and greater air duct surface l working temperature is higher than the dew point. Another way to save space is to create a heat exchanger with multiple cooling circuits to cool several fluids at once for example, a 4-circuit heat exchanger may be used to simultaneously cool air, oil, and egw via ram air or a fan. The hairpin heat exchanger design is similar to that of double pipe heat exchangers with multiple tubes inside one shell the design provides the flexibility of a u-tube design with an extended shell length that improves the exchanger’s ability to achieve close temperature approaches. Figures 2 and 3 present the variation of h 2 s and co 2 concentration in the sweet gas stream as a function of steam rate for mea, dea, and mdea figure 2 also indicates that the minimum steam rate to achieve common pipeline specification of h 2 s concentration of 4 ppm it should be noted that for the same h 2 s concentration in the sweet gas, mdea requires the lowest steam rate. I want to design a plate fin heat exchanger could anyone advise a good reference material to read and understand on designing from scratch i need to design a heat exchanger which can recover.
10 introduction the minor equipment that is designed in this project is lean/rich mea heat exchanger e-114 this heat exchanger is a counter flow shell and tube heat exchanger and is designed to heat up the rich mea stream flowing from the co2 absorber to the stripper. Heat transfer and heat exchanger design are sufficiently simple and parallel to mass transfer to be useful in explaining the utility of treating mass transfer as a rate process by the 1950’s heat.

Essay on mea heat exchanger design lean/rich mea heat exchanger e-114 this heat exchanger is a counter flow shell and tube heat exchanger and is designed to heat up the rich mea stream flowing from the co2 absorber to the stripper the principle that is. There are two main types of heat exchangers the first type of a heat exchanger is called the recuperative type, in which heat are exchanged on either side of a dividing wall by fluids the second type is regenerative type, in which hot and cold fluids are in the same space which contain a matrix of materials which work alternately as source. Compact heat exchanger are developed and their design and performance optimized relative to the criterion of minimum dry weight results for these optimizations are presented, comparisons mea more electric aircraft dew directed energy weapon tms thermal management subsystem.
