Abstract:
Potential for cogeneration in 28 pulp and paper plants is investigated in this work. Steam and electrity consumption data together with the annual production, were obtained directly from the plants and used in the evaluation study. From the records, the specific energy consumption values were found to be in the rang of 6.9 and 45.4 GJ/ton fo paper, with the average value being 23.34 GJ/ton. Calculations were also made on the heat-to-power ration values which were between 2.7 and 13.9, with 7.11 being the average value. The finding suggested the suitability of back-pressue steam-turbine cogeneration system which was subsequently used in the evaluation study. In the design of cogeneration system for each plant, thermal-matched criteria was employed. For each plant, the boiler steam pressure was varied in 13 steps, ranging from 30 to 150 bar, with the temperature varying in two values, saturated and 500C. These were done in order to find the optimum boiler settings. At each steam conditions, revenues and expenses arising from the use of cogeneration system were estimated, the net income of which was then compared with the investment cost to find the internal rate of return. By using 20% IRR or greater as criteria for viability, the results of the calculations show that cogeneration is viable for all plants. Since the study covers almost every plant in operation, it may be concluded that cogeneration has a very good potential in the pulp and paper sector
