Vertical Thermosiphon Reboiler - are commonly used in many chemical processes involving distillation, fractionation and stripping, supplying the necessary heat input into the process to drive the desired component mass transfer. |
U-Tube Exchangers - are sometimes used in process applications having high pressure, including partial condensing of vapors. This design is well suited for natural draining of condensate. The shell side may be cross-flow, as illustrated, or instead, type "E" or "F" shells. |
Tubesheet design - is very important in all applications of heat exchangers, to insure good performance and to permit inspection and cleaning. |
Cross Flow exchanger designs are often used to recover heat from process gas at a high temperature level into a vaporized fluid, such as in steam generation. Low shell side fluid pressure loss is a desirable benefit for cross-flow exchanger designs. |
Vacuum Steam Surface Condensers - are designed to maintain a vacuum exhaust pressure and recover the steam from large, multistage steam turbines that provide power for the fans, compressors and pumps in chemical plants. These large exchangers sometimes contain thousands of tubes to condense and recover steam from the chemical or power plant turbines. |
Special Cross Flow Exchangers - are used to achieve low fluid pressure loss in special design applications. Cross-flow exchangers are sometimes used to upgrade other moderate pressure drop type "E" and "J" heat exchangers to save energy. Great care must be taken in the design of cross-flow exchangers, so they will work properly. |
