    • The present invention relates to a method of catalytic production of ammonia, where a gas mixture consisting mainly of unconverted synthesis gas, some ammonia, inert gases and possibly also water is recirculated to the synthesis reactor being first freed from the main part of the ammonia and possibly also water by absorption. The gas mixture is brought in contact with a hygroscopic absorption agent having two or more OH-groups for absorption of ammonia and possibly also water. The absorption is carried out at a pressure being substantially the same as the ammonia synthesis pressure, and ammonia being desorbed from the absorption agent at a lower pressure and higher temperature than at the absorption. At least part of the possibly present water is removed from the absorption agent before it is supplied to the absorption column. Preferably it is applied ethylene glycol, diethylene glycol or triethylene glycol alone or in mixture as absorption agent. Possible water can be removed from the absorption agent by inert stripping gas before it is returned to the absorption column.
    • 本发明涉及一种催化生产氨的方法,其中主要由未转化的合成气,一些氨,惰性气体和可能的水组成的气体混合物再循环到合成反应器中,首先从氨的主要部分中脱除, 也可能通过吸收水。 使气体混合物与具有两个或更多个OH基团的吸湿剂接触以吸收氨以及可能的水。 吸收在与氨合成压力基本相同的压力下进行,氨在比吸收更低的压力和更高的温度下从吸收剂中解吸。 至少部分可能存在的水在被提供给吸收塔之前从吸收剂中除去。 优选单独使用乙二醇,二甘醇或三甘醇或作为吸收剂的混合物。 可能的水可以在惰性汽提气体返回到吸收塔之前从吸收剂中除去。

    • A sample container (1) especially for oil/gas samples consists mainly of a spherical body formed of two half parts (2, 3) with a metal membrane (4) fixed between the flanges of the two half parts. The membrane has a configuration complementary to the configuration of each half part and is substantially hemispherical with a planar portion (8) perpendicular to the in-/outlet passages (9, 10). The flange (13) of the membrane forms the packing between the two halves of the container. The membrane may be equipped with a reinforcement plate (14) perpendicular to the in-/outlet passages. To ensure that the container is leakage proof at large pressure variations, the container is at the oil/gas side equipped with a resilient packing nose (16) and labyrinth packing (17). The in-/outlet passages are formed as annular gaps (21). The container has only metallic packings.
    • 特别用于油/气样品的样品容器(1)主要由两个半部分(2,3)形成的球体,其中两个半部分的凸缘之间固定有金属膜(4)。 膜具有与每个半部分的构造互补的构造,并且具有垂直于入口/出口通道(9,10)的平面部分(8)的大致半球形。 膜的凸缘(13)在容器的两个半部之间形成填料。 膜可以配备有垂直于入口/出口通道的加强板(14)。 为了确保容器在大的压力变化下是防漏的,容器处于装有弹性填料鼻(16)和迷宫式填料(17)的油/气侧。 入口/出口通道形成为环形间隙(21)。 容器只有金属填料。
