A brief introduction to UOP’s third-generation regeneration technology

Thread Content

　　I just attended UOP’s technical conference and gained a rough understanding of UOP’s third-generation regeneration technology. Its features include: the skirt edge of the upper baffle in the reduction section has been replaced with a screen ； The reduction temperature was increased, and the C4 content in the reducing gas was controlled to less than 1%. The chlorine adsorption process was adopted, the regenerator was placed on the ground, and an L-valve assembly was used to lift it above the lock hopper, thereby resolving the issue of fluctuations in differential pressure control in the original nitrogen seal tank. 　That is, chlorine adsorption becomes the core element; the regeneration system is divided into two stages, and an L-valve assembly for nitrogen lifting is added to replace the nitrogen seal tank isolation system. In the regenerative chlorine injection process, a reheated gas heating step has also been added to control the higher chlorine oxidation temperature. Are you not quite clear about this step? 　A chlorine injection point is added before the flue gas returns to the regenerator.
