Baffle condenser, cross flow

Baffles in a horizontal in-shell condenser are oriented with the cuts vertical to facilitate drainage and eliminate the possibility of flooding in the upward cross-flow sections. Pressure drop on the vapor side can be estimated by the data and method of Diehl and Unruh [Pet. Refiner, 36(10), 147 (1957) 37(10), 124 (1958)]. 

Baffle cuts are expressed as the ratio of segment opening height to shell inside diameter. Cross-flow baffles with horizontal cut are shown in Fig. 11-36 7, c, andf. This arrangement is not satisfactoiy for horizontal condensers, since the condensate can be trapped between baf-... 

X shell is a cross flow shell. It does not have baffles. Shell side fluid flows across tube bundle to the other tdde of the shell. Pressure drop is low. For long tubes, more than one set of inlet/outlet nozzles will be used. Sometinies, perforated plates are used to help distribute the shell side flow across the tube bundle. It is mainly used for low pressure gas condensing service. [2]...
