Abstract: A method for the removal of sulfur and nitrogen containing compounds from petroleum distillates. Sulfur- and nitrogen-containing compounds are oxidized using a selective oxidant to create compounds that can be preferentially extracted from a petroleum distillate due to their increased relative polarity. Oxidation is accomplished by contacting an oxidant with a distillate under optimum conditions for that distillate and continuing the reaction until oxidized sulfur- and nitrogen-containing compounds are confirmed. Extraction is accomplished by contacting oxidized distillate with a non-miscible solvent that is selective for the relatively polar oxidized sulfur- and nitrogen-containing compounds. The oxidized compounds and solvent are separated from the distillate by gravity separation or centrifugation. The distillate is water washed and polished using clay filtration. The extraction solvent is separated from the solvent/oxidized compound mixture by a simple distillation for recycling. The high sulfur/high nitrogen fraction can be recovered using any number of treatments.

Abstract translation: 从石油馏分中除去含硫和氮的化合物的方法。 使用选择性氧化剂对含硫和氮的化合物进行氧化以产生由于其相对极性增加而能够从石油馏出物中优先提取的化合物。 氧化是通过使氧化剂与馏出物在最适条件下与该馏出物接触而进行的，并且继续反应，直到氧化的含硫和含氮化合物得到确认。 萃取是通过将氧化的馏出物与对相对极性的含氧化物和含氮化合物有选择性的不可混溶的溶剂进行接触而实现的。 通过重力分离或离心将氧化的化合物和溶剂与馏出物分离。 使用粘土过滤将馏出物进行水洗和抛光。 通过简单的蒸馏将提取溶剂与溶剂/氧化的化合物混合物分离以进行再循环。 可以使用任何数量的处理来回收高硫/高氮馏分。

The process is particularly advantageous when applied to to the residues, containing sulphuric acid, resulting from the synthesis of white oils from petroleum fractions. The present invention further relates to a method for fluidizing acidic tars/sludges including contacting the tar/sludge with sulfuric acid and a surfactant. Optionally, a carrier for the surfactant's incorporation into the tar/sludge can be utilized. This provides an effective process for cleaning sulfuric acid tars/sludges from containers/vessels such as transportation containers, pipes and storage tanks. Preferably, the process includes the additional step of regeneration of sulfuric acid from the fluidized tar/sludge.

Abstract: Disclosed is a method for removing sludge in a crude oil storage tank by use of thermal oil discharged from a distillation tower of an oil refinery, such as atmospheric residue, vacuum residue, or vacuum gas oil, and recovering oil having various applications by separating inorganics therefrom. The method is advantageous in terms of minimizing air pollution because of utilizing a closed system, drastically reduced washing time of crude oil storage tank, and continuous removal of the sludge. Additionally, the recovered oil can be provided as fuel oil, marine oil or a feed for secondary treatment processes, such as up-grading processes of heavy oil.
