摘要: Many linear alpha olefin (LAO) syntheses form a range of LAO products when oligomerizing ethylene in the presence of a Ziegler-type catalyst. The range of products typically requires a plurality of distillation columns to separate the LAO products up to a desired carbon count, but such approaches may be energy- and capital-intensive. LAO product separation using at least one dividing wall column may lessen these burdens. Methods for separating LAOs may comprise: providing a pre-processed product stream comprising Cg+ linear alpha olefins (LAOs) to a first of a series of distillation columns, at least one member of the series of distillation columns comprising a dividing wall column; and separating an overhead stream comprising a first LAO from the dividing wall column and one or more side streams from the dividing wall column, each side stream comprising a different LAO that also differs from the first LAO.

摘要: Systems and methods for determining the flow distribution of a fluid through a component with a sensing cable including an optical fiber sensor array aligned with a heating element disposed in the component. An excitation source is configured to propagate at least one heat pulse through the heating element along at least a portion of the sensing cable to affect an exchange of thermal energy between the heating element and the fluid exposed to the sensing cable. An optical signal is adapted to receive a signal from each of a plurality of sensor locations and measure a temperature profile corresponding to the heat pulse at the sensor locations. A control unit is configured to determine a flow of the fluid by determining one or more properties of the fluid exposed to the sensing cable at each of the plurality of sensor locations based on the temperature profile corresponding thereto. The present invention can be effective in accurate and high spatial resolution of flow distributions through vessel components, such as a particulate bed (such as a reactor catalyst bed), a wash bed including packing material, an absorbent bed, a structured bed, a filter, or the like.
摘要翻译: 用于通过传感电缆确定流体通过部件的流动分布的系统和方法,所述传感电缆包括与设置在所述部件中的加热元件对准的光纤传感器阵列。 激励源被配置为沿着感测电缆的至少一部分传播至少一个热脉冲通过加热元件,以影响加热元件和暴露于感测电缆的流体之间的热能交换。 光信号适于接收来自多个传感器位置中的每一个的信号,并且测量对应于传感器位置处的加热脉冲的温度分布。 控制单元被配置为基于与其对应的温度分布,通过确定在多个传感器位置中的每一个处暴露于感测电缆的流体的一个或多个属性来确定流体的流动。 本发明可以有效地准确和高空间地分辨通过容器部件的流动分布,例如颗粒床(例如反应器催化剂床),包括填充材料的洗涤床,吸收床,结构化床,过滤器 ,等等。
