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。
Looking ahead to the pulp mill in 2020, it is required to produce high quality bleached sulfate commercial wood pulp, which contains some recycled fiber pulp. There should be two pulp production lines in the factory: one is a raw fiber production line using the kraft pulping method, and the other is a regenerated fiber production line using the recycled fiber pulping. All chlorine-free bleaching (TCF) is used. In 2020, the pulp mill will reduce the water consumption of producing one ton of pulp. Wastewater is recovered, utilized, and evaporated, resulting in near-zero emissions from the factory’s wastewater. In 2020, the pulp mill will focus on the use of fuel gasification and gas turbine technology to increase the electricity/steam output ratio. The energy balance of a plant can have five programs. Among them, one is a traditional program, the second is a minimum investment program, and the remaining three are composite system solutions and composite system plus hybrid steam boiler supplemented system solutions.
