摘要： A process for isomerising a feed comprising aromatic compounds containing 8 carbon atoms is carried out in two steps: an isomerisation step and a dehydrogenation step. In FIG. 1, the feed to be treated is introduced into isomerisation zone R1 via line 1. Substantially pure hydrogen is introduced into line 1 via line 12 and recycled hydrogen is introduced into line 1 via line 13. Hydrogen which circulates in line 13 is purged via line 15. The effluent from isomerisation zone R1 is sent to a separation zone S1 via line 2. In S1, hydrogen contained in the effluent is isolated and recycled to the inlet to isomerisation zone R1 via line 13, the remaining effluent being evacuated from this separation zone S1 via line 3. The fluid contained in line 3 is heated in an oven F1 then evacuated therefrom via line 4. The effluent leaving the oven is enriched in recycled hydrogen via line 14 then it is introduced into dehydrogenation zone R2. The effluent from zone R2 is sent via line 5 to separation zone S2. In S2, hydrogen contained in the effluent is isolated and recycled to the inlet to dehydrogenation zone R2 via line 14, the remainder of the effluent being evacuated from separation zone S2 via line 6. Hydrogen which circulates in line 14 is purged via line 16.
摘要翻译：异构化含有8个碳原子的芳族化合物的进料异构化方法分两步进行：异构化步骤和脱氢步骤。在图 1，待处理的进料通过管线1被引入异构化区域R1中。通过管线12将基本纯的氢气引入管线1中，再循环的氢气通过管线13引入管线1中。在管线13中循环的氢气通过管线来自异构化区域R1的流出物通过管线2被送到分离区域S1中。在S1中，流出物中包含的氢气被分离并通过管线13再循环到异构化区域R1的入口，剩余的流出物从该分离管线3中包含的流体在烘箱F1中加热，然后通过管线4从其中排出。离开烘箱的流出物经由管线14富集回收的氢气，然后将其引入脱氢区域R2。来自区域R2的流出物通过管线5输送到分离区域S2。在S2中，流出物中所含的氢被分离并通过管线14再循环到脱氢区R2的入口，剩余的流出物通过管线6从分离区S2排出。在管线14中循环的氢通过管线16被清除。

摘要： For isomerising aromatic compounds containing eight carbon atoms in the presence of hydrogen, a mixture containing compounds with a boiling point of about 80° C. to 135° C. comprising at least one paraffin containing eight carbon atoms, at least one naphthene containing eight carbon atoms, at least benzene and at least toluene is added to the feed before introducing it into the isomerisation reactor R via line 1. These additions are made by a recycle via line 6 or by adding fresh compounds via line 11, or be a combination of fresh and recycled compounds via lines 6 and 11. Hydrogen is added via line 15.

摘要： A winch or capstan primarily for tightening the sails of a ship and having a winch head driven always in one direction only at a selected one of four speed ratios. A planetary transmission and free wheel arrangement provide two of the speed ratios corresponding to clockwise and counter-clockwise rotation of a control shaft. A sprocket and chain arrangement drive by handwheels is housed in two casings mounted at one end of the shaft, the driven sprocket in one casing being moveable into dog-clutch engagement with one or the other of two gear trains coupled with the shaft to provide the two further speed ratios.
摘要翻译：绞车或绞盘主要用于紧固船舶的帆船，并且绞车头总是沿四个速度选择的一个方向一个方向驱动。行星传动装置和自由轮装置提供对应于控制轴的顺时针和逆时针旋转的两个速比。通过手轮的链轮和链条排列驱动器被安装在安装在轴的一端的两个壳体中，一个壳体中的从动链轮可以与与轴连接的两个齿轮系中的一个或另一个齿轮传动装置啮合，从而提供两个进一步的速度比。
