Abstract

An apparatus and method for extracting and recovering water-soluble gas and waste heat from an oven is provided. The method employs a gas-gas heat exchanger for cooling hot stack gas from the oven to a temperature higher than the dew point of the hot stack gas, a double-film-wise heat exchanger for receiving the cooled stack gas from the gas-gas heat exchanger, a condenser/heat exchanger for receiving and further cooling the stack gas from the double-film-wise heat exchanger to ambient temperature by heating a utility water stream, which can then be used for hot water and steam process services, and an ethanol recovery unit for receiving the cooled stack gas from the condenser/heat exchanger.
