Combined Cooling, Heating and Power (CCHP) system is a cogeneration technology that integrates an absorption cycle to produce power, heating and cooling, simultaneously. It issometimes 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 steamturbine. 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 alsosimulated by Aspen plus software. Having implemented the proposed CCHP system, both heatingand 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<\div>
