SYSTEM FOR STRIPPING HYDROGEN SULFIDE IN WILD NAPHTHA DURING PROCESS OF PETROLEUM DESULFURIZATION

摘要

PURPOSE: An apparatus for stripping hydrogen sulfide in wild naphtha during a process of petroleum desulfurization is provided to prevent the depreciation of moisture contained in the wide naphtha and equipment corrosion due to residual hydrogen sulfide. CONSTITUTION: An apparatus for stripping hydrogen sulfide in wile naphtha comprises: a gas-liquid separator(19) separating a liquid material including the wild naphtha by collecting hydrogen sulfide gas which is produced from a sodium hydroxide removal tower(18) and discharging gas component; a stabilizer(20) which recycles the hydrogen sulfide by re-heating the liquid material using the gas-liquid separator and produces moisture without the hydrogen sulfide; and a pump transmitting the produced moisture to CPU process.
