| 20080264495 | Method and Apparatus for Preventing Slug Flow in Pipelines - Disclosed is a method and system for controlling the formation of liquid or gas slugs along a pipeline. In embodiments, an injection unit injects a liquid surface tension reducing agent, such as a foamant, into the pipeline upstream of the high point. A control unit can be used to control the injection unit. In certain arrangements, the control unit adjusts the injection of the agent based on measured parameters of interest. In embodiments where the control unit utilizes temperature measurements, one or more temperature sensors are positioned along the pipeline. The control unit utilizes the temperature measurements to determine whether a predetermined condition exists or a liquid or gas slug is present. | 10-30-2008 |

| 20090260694 | Method and apparatus for removing liquids from risers - A bypass assembly is provided for preventing unwanted liquids from collecting within fuel gas risers, exiting such risers and contaminating fuel gas systems. A conduit extends from a riser vessel to a natural gas flow line. An insert extends from the bypass line into the natural gas flow line. As production flows through the flow line and insert, a suction force is created that draws liquids from the riser into the conduit and, ultimately, back into the flow line system. | 10-22-2009 |
| 20100132804 | Pressure Equalizing Housing Device - There is provided a pressure-equalizing housing device, including a rigid housing having a coupling end and configured to contain at least one instrument. The coupling end of the housing is adapted to be sealable to a radiation transmittable surface. An opening made in a wall of the housing enables fluid to pass therethrough, and the housing and surface delimit an interior space communicating with the exterior of the housing via the opening. There is also provided a pressure-influenced member forming an expandable and retractable volume body, a portion of which member is located adjacent to, or the interior of which member communicates with, the opening, for equalizing the pressure inside and outside the housing. | 06-03-2010 |

| 20150034173 | CLOSED ANTIOXIDANT FLUID SYSTEM AND METHOD FOR PROMOTING ANTIOXIDANT PROPERTIES THEREOF - A hydraulic system primary fluid reservoir in fluid communication with an auxiliary reservoir having a cartridge and an elastic fluid impervious chamber and apparatus for sealing the elastic fluid impervious chamber with the interior thereof in fluid communication with the inside air of an associated primary fluid reservoir. Said cartridge contains an oxygen absorber that removes oxygen molecules from the reservoir air. The cartridge includes a desiccant to dry the reservoir air. A metallic heat conduction rod is partially exposed to internal air and partly exposed to ambient air. The conduction rod is in close proximity to the oxygen absorber and desiccant in the cartridge. A cool portion on the conduction rod attracts hot humid internal air causing condensation of water near the surface of the conduction rod. The temperature differential between the ends of the conduction rod during system operation and when off may result in a portion of the conduction rod being below the dew point temperature of the humid internal air. The moisture molecules in the internal air are drawn to and condense on the cooler surface of the conduction rod. The oxygen absorber and desiccant, in close proximity to the conduction rod, result in drying the air and removing oxygen molecules and this result in a high concentration of inert nitrogen gas above the oil thereby preventing oxidation of the oil. | 02-05-2015 |
