Title:
炭化水素ストリーム中の元素状硫黄および全硫黄レベルを低減する方法
Document Type and Number:
Japanese Patent JP5011107
Kind Code:
B2
Abstract:
A method for reducing the level of elemental sulfur from sulfur-containing hydrocarbon streams as well as reducing the level of total sulfur in such streams. Preferred hydrocarbon streams include fuel streams such as naphtha and distillate streams that are transported through a pipeline. The sulfur-containing hydrocarbon stream is blended with an aqueous solution of water, a caustic, and at least one metal sulfide thereby resulting in an organic phase and an aqueous phase. The blended stream is then passed through a bed of solids having a suitable surface area so that a substantial amount of the sulfur moieties are removed by the aqueous phase.
