<p>PURPOSE:To provide a method for removing mercury from unsatd. hydrocarbon- contg. gas incorporating mercury such as condensate decomposition gas. CONSTITUTION:Unsatd. hydrocarbon-contg. gas is brought into contact with a reacting agent consisting of the aq. soln. of multiple sulfide compd. expressed by MM'Sx (M and M' are sodium or potassium and may be the same or different and (x) is 2-9). By this method, mercury in the unsatd. hydrocarbon-contg. gas is removed as mercury sulfide., When the mixture soln. of multiple sulfide with sodium sulfide is used as a reacting agent, mercury can be dissolved to a high concn. Since this method can be operated at a normal temp., polymn. of olefilns can be relaxed and the influence of the decomposed gas containing unsated. hydrocarbon is suppressed.</p> |
