      Structured packing
      Product description:

      Absorption tower is a most important and necessary equipment in chemical engineering and oil refinery industries. Regular packing is a main unit for the development of tower technology. In order to promote the development of regular packing and expansion utilization in industries, our company through close cooperative investigations with related research institute has achieved rich experiences for the research, development, promotion of regular packing as well as the production of high-efficiency regular packing and tower elements, winning great faith in China. The applications of regular packing are expanded from general chemical industry to oil refinery, petrochemical industry, fine chemical industry, chemical fertilizer industry and environment protection departments. The operating units are expanded from distillation to absorption abstraction, washing, heat transfer and bi0Chemical pr0Cessing. The working process is also expanded from normal pressure, medium vacuum and separation to high-pressure evaporation. The regular packing tower equipment has been developed tending to large scale, computerized optimization and automatic operation. Practice proves that the new-type and high-efficiency regular packing is characteristic of high flux, high efficiency, low resistance, less liquid delay and easy operation without evident magnification effect.
