STRIPPING METHOD USING NITROGEN

摘要

The present invention relates to a method for stripping oils, produced at the intermediate part of a main stripper in an FCC process, using nitrogen, to thereby meet the inflammation point and appearance standards. The method of the present invention meets the inflammation point and reduces moisture to a level lower than a saturation level, and thus prevents appearance problems. The method of the present invention enables easy adjustment of the inflammation point, thus enabling oils to be directly mixed with kerosene products and diesel products. Further, the method of the present invention eliminates the necessity of additional equipment, and can be applied to conventional separators by simply connecting a nitrogen injection pipe, thereby achieving significant economical advantages.
