Ube Heavy Oil Gasification and Desulfurization Process

Abstract

Though the direct desulfurization processes have already been commercialized for the removal of sulfur in the heavy oil, the desulfurization degree is not satisfactory from the view point of today's air pallution problem. The fuel like LNG and naphtha is more and more required.
For this purpose, Ube process can successfully be applied; heavy residue oil being gasified in a unique fluidized bed, most of sulfur converted into H₂S, desulfurized in the gas phase by the conventional absorption process and the high calorie product gas 6, 000-8, 000kcal/Nm³ utilized as a fuel gas for combustion, which is practically completely free the sulfur compounds.
