Abstract: The paper described application of the combined technology of “deep desulfu-rization of liquefied hydrocarbon” and “redistillation of MTBE” to reduce the sulfur content in MTBE product in 250 kt/a desulfidation unit for liquefied petroleum gas .After the technical renovation, the goal of total sulfur content in MTBE less than 10μg/g was achieved, running of the unit of mercaptan removal for liquefied hydrocarbon was optimized such as reduction on ener-gy consumption ,alkali consumption and discharge of the alkali residue , improvement on quality of liquid hydrocarbon.The application results after the reform showed that sulfur content in MTBE could be stabilized below 10μg/g, which met requirements of harmonic Beijing standard V gas-oline.The overall running costs of the unit for desulfidation for MTBE and the unit of mercaptan removal for liquefied hydrocarbon were reduced greatly .
