Ceramic composite ring packing is for chemical, oil refining and gas off the washing, extraction and distillation of the specially developed new and efficient packing. The packing for multi-diamond, an increase of a combination of strength and specific packing surface area, and the overall loading of the packing unit and has made a significant improvement to solve the problem of baffle and the dead, the reaction speed and broaden the operating range. The improved considerably reduced the weight of the monomer. The weight of the tower filling a substantial decline in production efficiency and economic benefits to improve synchronization.
