    Abstract: Presented herein is a method for obtaining a dissolved selenium liquid mixture from solid selenium. The method involves mixing an amine solvent and a thiol solvent with the solid selenium to produce a liquid intermediate solution and removing a sulfur containing compound from the liquid intermediate solution to produce a dissolved selenium liquid mixture. A method for obtaining dissolved sulfur liquid mixture by mixing an amine with a thiol to produce a liquid solution that dissolves sulfur to produce a dissolved sulfur liquid mixture is also presented. In addition, a method for obtaining a dissolved sulfur and selenium liquid mixture from solid selenium and solid sulfur by mixing an amine solvent with a thiol solvent is presented.

    Abstract: Systems and processes for producing one or more alkenes from shale gas. The process includes at least two dehydrogenation reactors whereby propane, or a mixture of propane and butane, can be dehydrogenated in a first reactor and ethane can be dehydrogenated in a second reactor. The lighter components which serve as chemical inert and thermal mass are separated from the dehydrogenated product after each reactor.

    Abstract: For an n-component mixture (n≧3), an array of new distillation columns is disclosed with vertical partitions that allow independent control of the vapor flowrates in each partitioned zone, while operating the columns to produce constituent product streams. Specifically, all such more operable columns with vertical partitions for ternary and quaternary feed mixtures are illustrated. For a ternary feed, through extensive computation, the minimum heat duty for each of the new columns is same as for the FTC configuration. The new columns with vertical partitions become even more attractive when the vapor split between column sections must be controlled within a narrow range. Finally, it is disclosed how a new column with vertical partition(s) drawn for an n-component mixture can be adapted to distil feed mixtures that contain more than n-components.

    Abstract translation: 对于n组分混合物（n≥3），公开了一系列新的蒸馏塔，其具有垂直隔板，其允许独立控制每个分隔区域中的蒸汽流量，同时操作塔以产生构成产物流。 具体地，示出了具有用于三元和四元进料混合物的垂直分隔件的所有这样更可操作的柱。 对于三元进料，通过广泛的计算，每个新色谱柱的最小加热量与FTC配置相同。 当柱段之间的蒸气分离必须控制在窄范围内时，具有垂直分隔的新列变得更有吸引力。 最后，公开了如何为n组分混合物绘制具有垂直分区的新色谱柱可以适应于蒸馏含有多于n-组分的进料混合物。
