  • Patent number: 9023772
    Abstract: Corrosion by ammonia/amine salts in hydrocarbon streams such as distillation overhead streams that contain a mineral acid and water can be prevented, avoided or minimized by adding certain strong amines to the streams. The amines have a pKa between about 10.5 to about 12 and include, but are not necessarily limited to, dimethylamine, diethylamine, dipropylamine, diisopropyl-amine, di-n-butylamine, diisobutylamine, di-sec-butylamine, di-tert-butylamine, pyrrolidine, piperidine, and combinations thereof. If the hydrocarbon stream further includes a nitrogen-containing compound such as ammonia, a tramp and/or a residual amine which can form a corrosive salt with the mineral acid, then the added amine is a stronger base than the tramp or residual amine, if present. The amount of added amine is greater than total amount of nitrogen-containing compound, so that any corrosive salts formed are less corrosive than the salts that would otherwise form from the ammonia and/or tramp amine.

  • Publication number: 20120149615
    Abstract: Corrosion by ammonia/amine salts in hydrocarbon streams such as distillation overhead streams that contain a mineral acid and water can be prevented, avoided or minimized by adding certain strong amines to the streams. The amines have a pKa between about 10.5 to about 12 and include, but are not necessarily limited to, dimethylamine, diethylamine, dipropylamine, diisopropyl-amine, di-n-butylamine, diisobutylamine, di-sec-butylamine, di-tert-butylamine, pyrrolidine, piperidine, and combinations thereof. If the hydrocarbon stream further includes a nitrogen-containing compound such as ammonia, a tramp and/or a residual amine which can form a corrosive salt with the mineral acid, then the added amine is a stronger base than the tramp or residual amine, if present. The amount of added amine is greater than total amount of nitrogen-containing compound, so that any corrosive salts formed are less corrosive than the salts that would otherwise form from the ammonia and/or tramp amine.

  • Publication number: 20120101013
    Abstract: The present invention relates to additives for use in lubricant compositions to processes for producing the additives, and to the use of the additives in lubricants and in systems that are lubricated. More specifically, the additive includes a capped particle comprising: (i) one or more inorganic core particles; and (ii) one or more multi-block copolymers attached to the inorganic particles. The multi-block copolymer includes at least one nonpolar polymer block interposed between two polar polymer blocks. One polar polymer block is attached to the core particle, and at least a portion of the another polar polymer block is not directly attached to, the core particle. When used in a lubricant to lubricate a metallic surface of a workpiece, the capped particle preferably adheres to the metallic surface of the workpiece.

  • Patent number: 8153568
    Abstract: The present invention provides water-resistant grease which improves the resistance to peeling which occurs from the surface of a bearing composed of carbon steel for machine structural use or the like even in a strict lubricating condition in which water may penetrate into the water-resistant grease during the operation of the bearing, and a rolling bearing and a hub bearing which use the water-resistant grease and have a long life. The water-resistant grease is composed of non-water-based base oil, a thickener, and a water dispersant used as an additive. The saturated amount of water dispersible in the water-resistant grease is 30 to 60 wt %. The water dispersant capable of dispersing the water in the water-resistant grease is a surface active agent. The non-water-based base oil is mineral oil. The thickener is a urea-based compound. The present invention also provides a rolling bearing and a hub bearing in which the water-resistant grease is enclosed.
