Patent number: 12051486Abstract: Systems and methods include a method for oil-in-water content. A water injection hydraulic simulation model is calibrated using water disposal pressures and rates of a water disposal system of a gas oil separation plant, including generating baseline disposal pressures and disposal rates. The model is updated based on lab results estimating emulsion viscosity at different oil-in-water content levels. A sensitivity analysis is performed to evaluate changes in disposal pressures relative to the baseline in response to changes in water quality based on an oil-in-water emulsion content. Curves of disposal pressures versus disposal rates at different oil-in-water concentrations are generated using the changes in the disposal pressures. Changes in disposal pressures and disposal rates of the water disposal system are recorded, and the changes are compared against the generated curves.Type: GrantFiled: February 11, 2021Date of Patent: July 30, 2024Assignee: Saudi Arabian Oil CompanyInventors: Zaid A.

Patent number: 5885310Abstract: In the present invention, a solution of synthetic anionic surface active agents is at first prepared by mixing and homogenizing sodium polyoxyethylenealkylether sulfate and sodium alpha-olefin sulfonate (both are anionic surface active agents). Distillated water is added to this solution with mixing such that the mixture becomes a mousse-like emulsion that homogeneously contains a sufficient amount of air bubbles. A condensed emulsion fuel material is then produced by adding petroleum liquid fuel to the mousse-like emulsion with mixing. The concentrated emulsion fuel material and an emulsion fuel has an excellent chemical stability and does not separate to water and oil layers even after a long term storage. In addition, as it can be combusted at a high temperature boiler without requiring so much air, the emission of both soot (dust) and NOx are simultaneously reduced.Type: GrantFiled: December 11, 1997Date of Patent: March 23, 1999Assignees: Makoto Minamidate, Hisayoshi Tanaka, Yutaka HashimotoInventor: Makoto Minamidate
