An apparatus including at least one heat transfer zone (400) and at least one mass transfer zone (300). Two applications following the concept of staged heat and mass transfers are given. The first one relates to wastewater stripper overhead. The second one relates to recovering both heat and condensate from a steam boiler deaerator steam vent (35) by retrofitting the vent with an economizer.
