摘要： Methods and systems for separating para-xylene are disclosed. In one exemplary embodiment, a method for separating para-xylene includes the steps of providing a feed stream including para-xylene and other C8 aromatic hydrocarbons to a first adsorbent bed within a radial flow simulated moving bed chamber and providing a desorbent stream to a second bed within the radial flow simulated moving bed chamber. The method further includes circulating the feed stream and the desorbent stream radially within the radial flow simulated moving bed chamber to third and fourth beds within the radial flow simulated moving bed chamber. Still further, the method includes withdrawing an extract stream including the para-xylene from the third bed and withdrawing a raffinate stream including the other C8 aromatic hydrocarbons from the fourth bed.

摘要： Processes and apparatuses for relocating a reforming process heater service into the convection section rely on combining a flue gas recycle quench stream with the radiant section off gases entering the convection section. The uniformity of mixing influences the effectiveness of that quench stream. The more effective the quench stream is, the lower the equipment size required to manage the recycle design.

摘要： The present invention relates to an apparatus for vapor-liquid distribution. More specifically, the present invention relates to a vapor-liquid distribution device that may be used in an ionic liquid co-current vapor and liquid up-flow reactor designed to distribute vapor uniformly across the reactor cross section through restriction orifices on distributors located across the distribution tray.
