摘要： A method operable to remove contaminants from a contaminated fluid stream is provided. The process includes receiving the fluid stream containing contaminants. A first portion of the contaminants are removed from the fluid stream with a first scrubbing vessel. A first alkaline solution reacts with the contaminants such that the contaminants enter a contaminant solution. A remaining portion of the contaminants from the fluid stream is then removed with a at least one additional scrubbing vessel, wherein a second alkaline solution reacts with the contaminants such that part of the remaining portion of the contaminants enter a second solution. Water content is then removed from the fluid stream with a desiccating module, wherein the desiccating module outputs a clean fluid stream.

摘要： A method for mitigating fouling in a wash unit used in a hydrocarbon cracking process wherein the fouling is due to the presence of polymers and deposits thereof formed by condensation of carbonyl compounds contained within a feed stream of the wash unit. In one embodiment, the invention provides a method of mitigating fouling in a wash unit by introducing into the feed stream an effective amount of an additive including: an inorganic salt of dithionite; and an epsilon caprolactam or a 6-amino caproic acid derivable therefrom. The additive scavenges the carbonyl compounds contained within the feed stream and dissolves deposits of the polymers to thereby mitigate fouling in the wash unit.

摘要： A method of inhibiting the formation of fouling deposits occurring in spent caustic wash systems used for ethylene dichloride (EDC) manufacturing processes. Fouling occurs in these systems when they are in contact with EDC processing streams contaminated with oxygen-containing compounds, such as aldehydes. These deposits are formed in EDC processing streams contaminated with oxygen-containing compounds while in contact with a caustic solution having a pH>7. The invention comprises adding an effective deposit-inhibiting amount of a non-enolizable carbonyl compound to the caustic solution. Preferred non-enolizable carbonyl compounds are formaldehyde, glyoxal, benzaldehyde, p-anisaldehyde, formic acid, glyoxalic acid and paraformaldehyde.

摘要： A process for sweetening high mercaptan content gasoline or other liquid hydrocarbons is disclosed which utilizes aqueous caustic solution. A recycle stream is used to increase the conversion potential by reducing the relative mercaptan concentration of the untreated gasoline. Part of the treated gasoline effluent is recycled to the untreated feed. The treated gasoline has a low mercaptan concentration while the untreated gasoline is high in mercaptans. As the two streams combine, the feed to the unit becomes less concentrated in mercaptan compounds. In effect, the mercaptan concentration of the untreated gasoline has been diluted by the treated gasoline. Nitrogen inhibits the solubility of oxygen into gasoline. Nitrogen present in the recycle stream would create a system high in nitrogen and low in oxygen. By increasing the level of nitrogen, oxygen is limited in its ability to complete the sweetening reaction. In order to keep nitrogen from inhibiting oxygen, the gasoline effluent is sent to a low pressure separation vessel. in this vessel, nitrogen gas separates from the liquid gasoline. Part of this liquid gasoline stream is recycled to join with the untreated gasoline. The recycle gasoline is now free of nitrogen that would inhibit the solubility of oxygen.

摘要翻译： 公开了一种利用苛性碱水溶液使高硫醇含量汽油或其它液态烃变甜的方法。 再循环流通过降低未处理汽油的相对硫醇浓度来提高转化率。 经处理的汽油流出物的一部分再循环至未处理的进料。 经处理的汽油具有低硫醇浓度，而未处理的汽油具有高硫醇。 当两股流合并时，单位的进料在硫醇化合物中的浓度较低。 实际上，未经处理的汽油的硫醇浓度已被经处理的汽油稀释。 氮气可抑制氧气溶解在汽油中。 存在于循环流中的氮将产生高氮和低氧的系统。 通过提高氮的含量，氧气在完成甜味反应的能力上受到限制。 为了防止氮气阻止氧气，将汽油流出物送入低压分离容器。 在该容器中，氮气与液体汽油分离。 这种液体汽油流的一部分被再循环以与未处理的汽油接合。 回收汽油现在不含有会抑制氧气溶解度的氮气。
