展望2020年纸浆厂

The 2020 Pulp Mill

展望２０２０年纸浆厂，要求生产高质量漂白硫酸盐商品木浆，其中含有部份再生纤维纸浆。工厂应有两条纸浆生产线：一条是用硫酸盐法制浆的原生纤维生产线，一条是用再生纤维制浆的再生纤维生产线。采用全无氯漂白（ＴＣＦ）。２０２０年纸浆厂将降低生产一吨纸浆的耗水量。废水经过回收、利用和蒸发，使工厂的废水排放接近“０”排放。２０２０年纸浆厂将着眼于采用燃料气化和燃气轮机技术，提高电力／蒸汽的产出比率。工厂的能源平衡，可以有五个方案，其中：一个是传统方案，第二个是最低投资方案，其余三个是复合系统方案和复合系统加补充蒸汽锅炉的混合系统方案。

The 2020 pulp mill will produce high--quality bleached maraft market pulp, which containes legislated levels of recycled pulp. Mill operat with two producting lines. One will produce virgin fiber with kraft pulping process. The other will produce retycled fiber with recycled pulping process. Mill will use completely chlorine free bleaching (TCF).The 2020 pulp mill will reduce the water consumption per ton of product. The liquid efflueuts are reused and evaporated. Therefore, the resultant efrluent is approching zero discharge.The 2020 pulp mill will specific focus to using fuel gasification and gas--tubim technique, to increasing the electric power/steam producting ratio. The energy balance of the mill will have five alleruatives: One is conventional kraft mill power plant. Second is minimum cost power plant. The rest three are combined cycle and hydrid combined cycle with additionat steam generator.
