Patent number: 10429858Abstract: The present invention concerns a method of providing advisory controls for a desalter system. The method allows a user to continuously monitor performance of the desalter system, to continuously monitor position of the emulsion band (or rag layer), to control the emulsion band using demulsifiers, and to recommend to users how to maintain optimal pressure drop at the mixing device of the desalter system. This is achieved by using a first principles based model combined with a sensor to measure the position, quality and size of the emulsion band. The first principles based model takes into account the geometry of the desalter system, physical properties of the crude oil and water, as well as the operating conditions. Thus, the method provides users with sensing of an emulsion layer through direct measurements and also gives recommendations on appropriate corrective actions to be initiated during upsets.Type: GrantFiled: August 25, 2015Date of Patent: October 1, 2019Assignee: BL Technologies, Inc.Inventors: Vijaysai Prasad, Jayaprakash Sandhala Radhakrishnan, Jeffrey Allen Zurlo, Richard Stephen Hutte, Arjun Bhattacharyya, Manish Joshi

Publication number: 20160354729Abstract: A selective membrane, for example an ultrafiltration, nanofiltration or reverse osmosis membrane, has a layer comprising flakes of graphene, graphene oxide, reduced graphene oxide, or functionalized variations. The flakes may form a layer themselves, be embedded in the surface of a layer of another compound, or be dispersed in a layer of another compound. In some cases, the flakes functions as a selective membrane. In other cases, the flakes modify the properties of a membrane, for example by making the membrane more hydrophilic. In yet other cases, the flakes function as a bonding agent between layers of a membrane.Type: ApplicationFiled: April 12, 2013Publication date: December 8, 2016Applicant: General Electric CompanyInventors: Kalaga Murali KRISHNA, Arjun BHATTACHARYYA, Rebika Mayanglambam DEVI, Madhuri PHADKE

Patent number: 9255228Abstract: The present invention concerns a method of providing advisory controls for a desalter system. The method allows a user to continuously monitor performance of the desalter system, to continuously monitor position of the emulsion band (or rag layer), to control the emulsion band using demulsifiers, and to recommend to users how to maintain optimal pressure drop at the mix valve of the desalter system. This is achieved by using a first principles based model combined with an ultra-sound sensor. The ultra-sound sensor measures the position, quality and size of the emulsion band. The first principles based model takes into account the geometry of the desalter system, physical properties of the crude oil and water, as well as the operating conditions. Thus, the method provides users with sensing of an emulsion layer through ultrasound measurements and also gives recommendations on appropriate corrective actions to be initiated during upsets.Type: GrantFiled: April 2, 2014Date of Patent: February 9, 2016Assignee: General Electric CompanyInventors: Vijaysai Prasad, Jayaprakash Sandhala Radhakrishnan, Jeffrey Allen Zurlo, Richard Stephen Hutte, Arjun Bhattacharyya, Manish Joshi
