Patent number: 12123593Abstract: Disclosed herein are systems, apparatuses, and methods for using a sensed combustion zone temperature to continuously control combustion of a first (main) gas within an enclosed combustor. The combustor is in fluid communication with a first gas line carrying the first gas, a second gas line independent of the first gas line carrying a second (assist) gas having a higher heating value than the first gas, and air dampers providing draft or assist air. The first gas may be vapors from a production source or tank. A computer control system monitors the combustion zone temperature of the enclosed combustor as sensed by a sensor in electronic communication with the computer control system and controls the combustion zone temperature by changing a condition of a first gas line valve of the first gas line, a second gas line valve of the second gas line, and the air dampers.Type: GrantFiled: June 27, 2023Date of Patent: October 22, 2024Assignee: CAMERON INTERNATIONAL CORPORATIONInventors: Rafiqul Khan, Herman C. Hatfield, II, Ankur D. Jariwala, Gary W. Sams

Patent number: 9751027Abstract: A method and system for controlling an interface emulsion layer within an oil treatment vessel includes injecting a water flow through a plurality of radial eductors arranged about a radial eductor manifold located in the brine water layer. Each radial eductor is oriented vertically to the radial eductor manifold and the horizontal axis of the oil treatment vessel. The water flow through the plurality of radial eductors causes a swirling flow pattern in a volume of water around each radial eductor that is effective for promoting a collapse of the interface emulsion layer. The water flow through each radial eductor, which may be a recycled water flow, may be in a range of about 1 to 5 feet per minute.Type: GrantFiled: February 18, 2016Date of Patent: September 5, 2017Assignee: Cameron International CorporationInventors: Rafiqul Khan, Joseph Min-Hsiun Lee, Gary W.

Patent number: 9422484Abstract: A method and system for controlling an interface emulsion layer and mud layer within a desalter vessel includes injecting a water flow through a plurality of nozzles arranged about a piping circuit located in the brine water layer. Each nozzle is oriented toward an interior space of the desalter vessel and is arranged oblique to the piping circuit. The water flow through the plurality of nozzles causes a horizontal and vertical rotation of a volume of water that is effective for suspending solids in the water and promoting a collapse of the interface emulsion layer. The water velocity through each nozzle, which may be a recycled water flow, is preferably in a range of 1 to 3 fpm and each nozzle is preferably oriented at an angle of about 15° and 60° in a horizontal plane and a downward angle of about 15° and 60° in a vertical plane.Type: GrantFiled: December 23, 2013Date of Patent: August 23, 2016Assignee: Cameron International CorporationInventors: Ronald D. Hypes, Jaime J. Castro, Francisco E. Vera, Marcus D. Sprenkel, Rafiqul Khan
