Process for withdrawing a vaporous bottom product from a low-temperature rectification column at less than 1 mole per hour

摘要

a tritium quantity of less than 1 mol per hour is continuously the verdampferraum (la) of a tieftemperatur - rektifikationskolonne (1) by means of a withdrawal device removed.;this withdrawal device essentially consists of two parallel vakuumtanks (8a and 8b), with the verdampferraum (1a) on a entnahmeleitung (5)in a control valve (6) is arranged alternately are connected.during operation is one vakuumtank (8a or 8b) with the tieftemperatur - rektifikationskolonne (1) in conjunction with tritium and filledwhat then is supplied to a consumer.as soon as a vakuumtank (8a or 8b) is filled with tritium and its emptying beginsthe second vakuumtank (8b or 8a) to the verdampferraum (1a) connected to and in analog manner filled and then emptied.;the advantage of this approach is that pure tritium as a product is obtained and the rectification is not disturbed.
