METHOD OF DISPERSING IRON SULFIDE IN LIGHT HYDRO- CARBON (C1-C6) DISTILLATION COLUMNS

摘要

of the Invention The present invention is directed to a method of dispersing iron sulfide to avoid deposition thereof in light hydrocarbons (Cl-C6,i,e., methane through hexane including isomers thereof) distillation columns in gas purification. More specifically it has been discovered that iron sulfide deposits commonly encountered in light hydrocarbon distillation columns can be controlled by adding to the light hydrocarbon a dispersant agent produced by the reaction of a succinic acid or anhydride derivative with a polyamine.
