Abstract
The condenser heat exchanger includes a housing that provides a gaseous stream flowpath and a bottom wall. A gaseous stream contains acid. The housing has a fluid inlet configured to introduce a liquid, such as water. A coolant tube is disposed within the housing in the gaseous stream flowpath and provides a coolant path. Acid condenses on and falls from the coolant tube into a collection area that is provided at the bottom wall near the coolant tube. The collection area is configured to maintain storage of a predetermined amount of fluid that includes the liquid, which dilutes the condensed acid.
