REVAP® cycle : A new evaporative cycle without saturation tower

A new evaporative cycle layout is disclosed that is shown to have a performance similar to the HAT cycle, but where the saturation tower has been eliminated. This new cycle is a result of a combined exergetic and composite curve analysis discussed in a previous paper, assuming one intercooler and no reheat (De Ruyck et al., 1995). The new cycle uses two-phase flow heat exchange in the misty regime, which is a well-known process. Existing aeroderivative gas turbine equipment can be adapted for application of this cycle, which therefore needs a minimum of development.
