Combined Cooling, Heating and Power (CCHP) system is a cogeneration technology that
integrates an absorption cycle to produce power, heating and cooling, simultaneously. It is
sometimes referred to as tri-generation system. In this study, the implementation of a CCHP
system in a pulp and paper industry is studied, which consists of a gas turbine, a power generator,
a HRSG system and an absorption heat pump (AHP) driven by the steam discharged from a steam
turbine. Pinch analysis is applied to find the appropriate placement of the proposed CCHP system
in black liquor concentration section of the process. Thermo flow and Aspen plus softwares are
used to simulate the turbine cycle and AHP, respectively. The concentration section is also
simulated by Aspen plus software. Having implemented the proposed CCHP system, both heating
and cooling requirements are reduced by 5.8 MW. This scheme also could produce 37.3 MW of
electrical power, with the payback of 1.1 years
