    摘要： A multiple pass, parallel flow downcomer tray for a mass transfer column and method for liquid-vapor contacting in a mass transfer column is provided. The multiple pass, parallel flow downcomer tray has at least four mass transfer decks configured to provide contact between an ascending vapor passing upward through apertures on the tray surface and a traversing liquid on the tray surface. The tray further includes a central downcomers disposed near a central axis of the tray and two or more peripheral downcomers disposed near the edge of the tray and spaced apart from the central axis, wherein at least two of the four mass transfer decks are configured to discharge the traversing liquid into the peripheral downcomers and two of the four mass transfer decks are configured to discharge the traversing liquid into the central downcomer.

    摘要： The present invention provides a vapor-liquid contact device for use in a distillation column and method incorporating the use of such a vapor-liquid contact device. The vapor-liquid contact device has arrays of elongated strips to support a falling film of a liquid and contact of a vapor with the film. The strips are supported in a structure having top and bottom sections connected to opposite ends of the strips. The top sections have apertures in registry with the strips so that liquid distributed to the top section seeps out of the apertures to initiate formation of the falling film. Openings are provided at the top and bottom sections, so that a vapor is able to pass through the support structure to contact the falling film to effect contact between the liquid and the vapor. Liquid distributors are associated with the top section to distribute the liquid to the apertures.

    摘要翻译： 本发明提供了一种用于蒸馏塔的气液接触装置和结合使用这种气液接触装置的方法。 气 - 液接触装置具有细长条的阵列，以支撑液体的降膜和蒸气与膜的接触。 条带被支撑在具有连接到带的相对端部的顶部和底部部分的结构中。 顶部具有与带对准的孔，使得分配到顶部的液体从孔中渗出以启动降​​膜的形成。 开口设置在顶部和底部，使得蒸汽能够穿过支撑结构以接触降落膜以实现液体和蒸气之间的接触。 液体分配器与顶部部分相关联以将液体分配到孔中。
