本集团是1982年9月成立的制浆造纸技术研究会的成员单位，主要从事高固含量黑液技术的改进。我们的研究是按照以下时间表进行的。1984年：中试装置的建设（417 B.D. kg/hr） 1985年：中试装置的运行为获得高浓度黑液，研制了盘式蒸发器。采用盘式蒸发器，可制得DS为8090%的黑液。介绍了高固体黑液的沸点升高和粘度。由于实验的目的是确定将黑液浓缩到较高固体水平的可能方法，因此粗略地考虑了经济方面。1985年的中试规模研究将确定碟式蒸发器的经济性和能源效率。
As a member of the Research Association of Pulp and Paper Technology established in September, 1982, our group is engaged in improving the technology of high solids concentration of black liquor.Our studies are being carried out according to the following schedule.19831984 : Bench-scale experimemt (120 B.D. kg/hr) 1984 : Construction of pilot plant (417 B.D. kg/hr) 19851986 : Operation of pilot plantDisc Evaporator has been developed in order to obtain high concentration black liquor.By using Disc Evaporator, we have produced 8090% DS black liquor.Boiling point rise and viscosity of high solids black liquor are presented.The economic aspects are roughly considered, because the objective of bench-scale experiment is to identify possible means for concentrating black liquor to higher solids level.Pilot scale studies, in 1985, will define the economy and energy efficiency of Disc Evaporator.
