摘要： An apparatus for reducing the energy consumption of a distillation column (10) is disclosed. The apparatus draws off an intermediate vapor stream (60) from the rectification section (20) of the distillation column (10), where the vapor stream is compressed and used to reboil a portion of the bottoms stream. The compressed vapor stream transfers energy to the bottoms stream, thereby condensing a portion of the vapor stream while vaporizing the bottoms stream.

摘要： Apparatuses and methods are disclosed for contacting radially flowing fluids with solid particles (e.g., catalyst) with reduced tendency for fluidization of the particles, and especially a sealing portion of the particles at the top of a particle retention zone disposed between screens at upstream and downstream positions relative to radial fluid flow. Fluidization is reduced or eliminated by offsetting openings of the screens in the axial direction, such that upstream openings in the upstream screen are above highest downstream openings in a downstream stream. The offset in openings imparts a downward flow component to radially flowing fluid, thereby reducing solid particle fluidization without the need to induce a specific pressure drop profile along the entire axial direction of the screens.

摘要： Processes and apparatuses for regenerating catalyst particles are provided. The processes include introducing spent catalyst particles to a burn zone in a continuous catalyst regenerator. When introduced, the catalyst particles, which contain a platinum group metal, carry coke deposits. In the process, a combustion gas at a temperature of at least 490°C with an oxygen content of at least 0.5 mol% is fed to the burn zone. There, the coke deposits on the catalyst particles are combusted with the combustion gas. The catalyst particles are passed from the burn zone to a halogenation zone in the continuous catalyst regenerator and the catalyst particles are oxyhalogenated to redisperse the platinum group metal to form regenerated catalyst particles.
