چکیده
Water and Energy are essential commodities in a pulp and paper mill. Larger amount of water consumed and effluent generated within the mill, result larger energy required to heat, cool and pump these streams. Therefore, the interactions between mill water and energy usage should be analyzed together through a systematic analysis of mill energy and water consumption. The aim of this study is implementing cost-efficient energy savings in the low water consumption level pulp and paper industries. In this work, a general methodology based on Pinch Technology is presented which shows potential for energy conservation while reduction of water consumption. The live steam demand for the mill decreases while the mill`s hot water consumption is reduced. Also by decreasing the hot water consumption, quantity and temperature of available excess heat increases and by using the remaining excess heat for evaporation, yields a significantly larger energy savings for the mill.کلیدواژه ها

اطلاعات بیشتر در مورد COI
COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
