从富烃馏分中分离重烃的方法
摘要：
本发明公开了一种用于从待液化的富烃馏分中，尤其从天然气中分离重烃，尤其是C6+-烃和/或芳香烃例如苯的方法，在重烃(7)分离(T1)之前，将富烃馏分(1)预冷(E1)。至少以避免待分离出的重烃(7)冷冻析出的这种含量，优选以液体形式，将一种或多种富C5-烃馏分(14，15)在其预冷(E1)之前混入富烃馏分(1)中，和/或混入用于分离出重烃(7)的脱除塔(T1)中。
摘要（英）：

Disclosed is a method for separating heavy hydrocarbons, in particular C6+ hydrocarbons and/or aromatic hydrocarbons, such as benzene, from a hydrocarbon-rich fraction to be liquefied, in particular from natural gas, the hydrocarbon-rich fraction (1) being pre-cooled (E1) prior to separation (T1) of the heavy hydrocarbons (7). One or a plurality of C5- hydrocarbon-rich fractions (14, 15) are mixed into the hydrocarbon-rich fraction (1) prior to the pre-cooling (E1) thereof and/or into the separation column (T1) used for separating (T1) the heavy hydrocarbons (7) at least in such a quantity, preferably in liquid form, that freezing of the heavy hydrocarbons (7) to be separated is prevented.
