The adverse impact of carbon dioxide and air on the thermal performance of condensers used in multistage flash (MSF) distillation plants is addressed. For normal operating conditions, the inlet gas flow rates are not sufficient to affect the thermal performance significantly. The heat duty for a typical condenser design is then determined for a broad range of entering noncondensable gas flow rates and vent flow rates. When the inlet steam/CO/sub 2/ mass ratio falls below about 250, the thermal performance is strongly affected by the noncondensable gases. When the vent flow rate approaches the minimum vapor/gas ratio based on the coolant temperature, a sharp drop in thermal performance also occurs. However, the thermal performance is not sensitive to the vent flow rate when it is about twice this minimum value.
