Abstract

Energy auditing is one of the steps made in an effort to realize energy saving programs. The energy widely used in the pulp and paper industries is thermal energy (steam) and electrical energy. Pulp drying is one of the processes that many use such energy. The thermal energy used was of low to medium pressurized steam, which used to increase air temperature to dry pulp sheet. Research were conducted to identified energy usage and potency of energy saving in pulp machine especially in Pulp machine 1 and 2 area. The results of the study were found the influence of downtime to production cost. 30 minutes down time will increase production cost to $0.3545/ton pulp. Used of acacia as raw material will make pulp machine possible to run 1 screening system. It give benefit $ 2180.8 per day. Besides, the study also found four “steam trap” units and six “valve” units with “Passing" (leaking)” conditions that made “losses steam” of 467.8 Kg/hr or 1,467 tons of steam/year or about IDR 240.051,840 in a year. The inverse improvements/recovery of “steam trap” positions can save steam with a saving percentage of 0,34% of total steam costs per year and will return investment capital for four hours. Whereas the turnover on leaked “steam trap” units could save steam of 2,574 tons of steam/year with a savings percentage of 0.60% of total steam cost per year and would return investment capital for four months.Keyword: Electricity, Energy Audit, Pulp Dryer, Steam

Abstract

Energy auditing is one of the steps made in an effort to realize energy saving programs. The energy widely used in the pulp and paper industries is thermal energy (steam). Pulp drying is one of the processes that many use such energy. The thermal energy used was of low to moderate pressurized steam, which was supplied into a number of rotating dryer cylinders. Evaporation is done because water can no longer be removed from the fiber by gravity and vacuum in the forming of the unit and mechanically in the pressing of the unit. The results of the study were found two “steam trap” units with “inverted” installation positions and four “steam trap” units as well as six “valve” units with “Passing" (leaking)” conditions that made “losses steam” of 467.8 Kg/hr or 1,467 tons of steam/year or about IDR 240.051,840 in a year. The inverse improvements/recovery of “steam trap” positions can save steam with a saving percentage of 0,34% of total steam costs per year and will return investment capital for four hours. Whereas the turnover on leaked “steam trap” units could save steam of 2,574 tons of steam/year with a savings percentage of 0.60% of total steam cost per year and would return investment capital for four months.Keywords : Pulp Dryer, Energy Consumption, Energy Saving, Steam Trap, Losses Steam
