SK Corporation has developed over the past few years a unique technology, called SK HDS Pretreatment Process, to produce the 10 ppm ULSD. The technology is based on the adsorption technique, and is designed to remove NCC from the feedstock to the HDS process to improve the performance of conventional HDS units, by removing effectively the components that inhibit the desulfurization reaction in the HDS unit. The main advantages of this technology combined with the conventional HDS units, over two stage HDS process, for producing 10 ppm ULSD are lower capital cost to install the unit, enables lower pressure and temperature, and requires less hydrogen. This paper describes the details of the technical aspects of the process in the followings. |
