First, energy. Low resistance of the plate with high efficiency, lower reactor temperature, amount of return, the establishment of rational use of energy in the distillation process at all levels; maximize the use of instrumentation control or computer controlled systems, load the equipment in the best condition.
Second, the production of high strength. Enhance the tower section of the vapor-liquid unit flux, especially for the design of the tower mash, but also should pay attention to the relationship between the vapor-liquid ratio. The equipment more compact, production capacity can increase strength and one of the methods, the use of efficient tray instead of the original old school tower (the tower does not move).
Third, the sewage performance. To minimize the mash in the matter content of fiber, while also considering its adaptation of equipment containing solid distillation of the fermentation broth, cut clean to minimize the number of towers.
Fourth, the full account of the amplification effect of tower. Especially the annual output of 15,000 tons of tower equipment, the column diameter are more than 1.5 meters, so the large diameter distillation equipment to take positive advanced measures to reduce the separation efficiency.
Fifth, the structure is simple, cost reduced. Conditions in the permit process, the choice of tray structure is simple and highly efficient new tray. |
