    • PURPOSE: A sulfones separation process using two-step absorption which uses methanol as polar solvent is provided to minimize operation cost and energy consumed in the separation during a process of separating sulfones from fraction containing sulfones. CONSTITUTION: Diesel containing sulfones is passed through absorber and then sulfones is absorbed in the absorber. A polar solvent is supplied to the absorber, and the absorber is recycled by dissolving and dissembling the sulfones absorbed in the absorber with the polar solvent. The polar solvent, by which the sulfones is dissolved, is passed through active carbon, and the polar solvent is recycled by absorbing and separating the sulfones dissolved in the polar solvent with the active carbon. Hydrocarbon is supplied to the active carbon in which the sulfones is absorbed, and thus the sulfones is separated from the active carbon. The sulfones is separated and collected from the hydrocarbon by distilling the hydrocarbon in which the sulfones is included. The absorber uses acidified silica. The polar solvent uses methanol. The active carbon is made by increasing surface polarity by activating carbon powder, whose pore size is 0.3-0.6 nm, in the temperature of 800 - 1000°C for 4-6 hours as supplying CO2.

    • A method and an apparatus for enrichment of ethylene from FCC(Fluid Catalytic Cracking) off-gas are provided to treat a large volume of off-gas by desorbing and recovering the ethylene using a desorbent after adsorbing ethylene onto an olefin selective adsorbent, and to protect an adsorbent used in the enrichment of ethylene by removing water contained in the off-gas through a pre-treatment adsorption process. A method for separating ethylene from FCC off-gas comprises: a pre-treatment process including an adsorption step of introducing FCC off-gas to adsorb water and a desorption step of introducing an ethylene removing stream exhausted from the ethylene separation process to clean and desorb the adsorbed water; and an ethylene adsorbing and separating process including an adsorption step of introducing the pre-treated FCC off-gas into an adsorption tower to adsorb ethylene, and sending non-adsorbed components and an adsorbent in the adsorption tower to a distillation tower for separating the ethylene removing stream and an adsorbent, an ethylene cleaning step of introducing a portion of high concentration olefin obtained from an ethylene enriched stream/desorbent distillation tower into the adsorption tower to increase the purity of ethylene, and a desorption step of introducing a desorbent into the adsorption tower to desorb ethylene and sending the desorbed ethylene to a distillation tower for separating a mixture of the ethylene enriched stream and the desorbent to produce an ethylene enriched stream.
