Patent application number | Description | Published |
20080308503 | Separation process - A separation process for separating two or more immiscible liquids using fiber-film technology is disclosed. This separation process is especially useful in the separation of disulfide oil formed during the oxidation of spent caustic solution that was used to remove sulfur contaminates from light hydrocarbons. | 12-18-2008 |
20090065434 | Removal of residual sulfur compounds from a caustic stream - A process for the removal of residual sulfur compounds from a liquid caustic stream is disclosed. One embodiment of my invention adsorbs disulfides from a caustic stream using an activated carbon adsorbent while another combines both oxidation and adsorption in single step to remove residual sulfur compounds from a rich caustic stream using metal phthalocyanine supported on a solid adsorbent. This process is especially useful as a polishing step in a caustic regeneration process flow scheme. | 03-12-2009 |
20100320124 | SEPARATION PROCESS - A separation process for separating two or more immiscible liquids using contactors utilizing high surface area vertical hanging fibers is disclosed. This separation process is especially useful in the separation of disulfide oil formed during the oxidation of spent caustic solution that was used to remove sulfur contaminates from light hydrocarbons. | 12-23-2010 |
20110127194 | Hydrocarbon Treatment Process - In a catalytic treatment process, mercaptans in sour hydrocarbon are oxidized to disulfide oils using an aqueous treatment solution containing a chelated polyvalent metal catalyst, alkali metal hydroxide, and the alkali metal salt of at least one alcohol in a non-dispersive mixing apparatus wherein an upgraded hydrocarbon containing the disulfide oils is produced. | 06-02-2011 |
20110163008 | HYDROCARBON TREATMENT PROCESS - In a catalytic treatment process, mercaptans in sour hydrocarbon are oxidized to disulfide oils using an aqueous treatment solution containing a chelated polyvalent metal catalyst, alkali metal hydroxide, and the alkali metal salt of at least one alcohol in a non-dispersive mixing apparatus wherein an upgraded hydrocarbon containing the disulfide oils is produced. | 07-07-2011 |
20130020239 | APPARATUS FOR TREATING A WASTE STREAM - An integrated unit operations for the treatment of a waste stream, such as spent caustic, is provided in a single vertical vessel having at least three separate zones: a mixing, a settling, and a mass transfer zone. | 01-24-2013 |
20130026086 | SEPARATION PROCESS - A separation process for separating two or more immiscible liquids using contactors utilizing high surface area vertical hanging fibers is disclosed. This separation process is especially useful in the separation of disulfide oil formed during the oxidation of spent caustic solution that was used to remove sulfur contaminates from light hydrocarbons. | 01-31-2013 |
20140014593 | Contactor and Separation Apparatus and Process of Using Same - In an improved fiber-film type contactor/separator an enhanced coalescing zone is provided by the presence of a disengagement device connected to a shroud that contains a bundle of high surface area vertical hanging fibers, where the enhanced coalescing zone diverts a portion of an admixture of immiscible liquids to flow radially in a path not parallel to the vertical axis of the hanging fibers whereby the diverted portion of liquids contacts a coalescing surface to cause at least one of the liquids to coalesce into droplets. The immiscible liquids are allowed to settle into separate phase layers and first and second outlets selectively remove the higher density liquid from the lower density liquid. | 01-16-2014 |
20150048006 | HYDROCARBON TREATMENT PROCESS - In a catalytic treatment process, mercaptans in sour hydrocarbon are oxidized to disulfide oils using an aqueous treatment solution containing a chelated polyvalent metal catalyst, alkali metal hydroxide, and the alkali metal salt of at least one alcohol in a non-dispersive mixing apparatus wherein an upgraded hydrocarbon containing the disulfide oils is produced. | 02-19-2015 |
