【Abstract】 To make a full use of resource, a set of light hydrocarbon recovery system has been added in the atmospheric and vacuum distillation unit of Dalian West Pacific Petrochemical Company. However, the H 2S content and copper corrosion test have not been met the quality standard of civil LPG after the unit started up and the operation of the debutanizer is unstable. So LPG caustic washing desulfurization has been adopted and the feedstock inlet of the debutanizer altered. H 2S content of LPG has been reduced from 20 μg/g to 0.75 μg/g, copper corrosion test decreased from 2 grade to 1 grade with a stable operation of the debutanizer. Quality standard of civil LPG has been met.更多还原
