  • System and method for recovering cooling capacity from a factory exhaust gas
    Patent number: 6348088
    Abstract: A system and a method for recovering energy from a low temperature factory exhaust gas are disclosed. In the system, a heat exchanger is added between a wet scrubber and a cooling tower such that a low temperature scrubber exhaust gas can be utilized to decrease the temperature of a heat transfer medium used in the cooling tower. The lower temperature cooling tower water therefore increases the efficiency of cooling in a chiller connected to the cooling tower. Furthermore, the increased scrubber exhaust gas temperature reduces its opacity to fulfill requirement of environmental protection regulations. The lower water temperature in the cooling tower further reduces water evaporation rate and therefore reduces water consumption due to evaporation.
