—Carbon dioxide from exhaust heat emission is one
of the major contributorsto the environmental pollutant in
power generation plants. This problem could be addressed if the
emitted exhaust heat is recovered. In cogeneration plant, the
exhaust heat from the gas turbine is used to generate steam
usingHeat Recovery Steam Generator. The steam from Heat
Recovery Steam Generator is then used for chilled water
generation in Steam Absorption Chillers by absorption process.
This study analyzed the total estimated amount of CO2 released
to the environment due to chilled water production by using gas
turbine exhaust heat. University Teknologi PetronasMalaysia
cogeneration system is used as a case study. The energy balance
principlewas adopted for the analysis. Results indicate that
approximately 44% of CO2is avoided from being released to the
environment by this process.

cogeneration and exhaust heat.
