20100304018 | Controlling Top of the Line Corrosion in Hydrocarbon Pipelines - The invention relates to applying corrosion inhibitor within a foam matrix to the top of the line of wet gas pipelines. The environment within a hydrocarbon containing pipeline may include fluids that form strong acids in the gas space at the upper portion of the pipeline and can rapidly corrode a carbon steel pipeline. The inventive solution is to provide a foam matrix created by a combination of foaming agent, foaming gas and corrosion inhibitor that are each selected to be compatible with each other and with the hydrocarbon mixture to form a stable foam matrix that treats the top of the line position for the length of the pipeline. A foam breaking agent at the end of the pipeline can be injected, if needed. | 12-02-2010 |
20110007310 | On-Line/At-Line Monitoring of Residual Chemical by Surface Enhanced Raman Spectroscopy - Target chemicals are monitored at very low concentrations in pipelines or vessels such as storage tanks using surface enhanced Raman spectroscopy analysis of a sample. A liquid sample having a target chemical such as biocides, corrosion inhibitors, scale inhibitors, anti-foaming agents, emulsion breakers, and hydrate inhibitors are tested while exposed to a prepared and charged surface of a coupon so as to draw the target material to the prepared and charged surface. The charged surface is fairly precisely charged using two other electrodes to calibrate the charge on the surface of the coupon. With the target substance presumably drawn to the coupon, the molecules on the surface of the coupon are excited by monochromatic light such as from a laser to induce vibrations within the molecules. The vibrations of the molecules reflect and scatter the monochromatic light in distinctive manners such that the collected light from the surface provides an indication of the presence of the target substance in the sample and a quantitative indication of the concentration of the target material in the sample. With the ability at lower power and reasonable cost to sense the presence well down below one percent and into the ppm range provides the opportunity to more precisely and efficiently add such chemicals to operating pipelines and storage tanks. | 01-13-2011 |

20110067497 | HIGH PRECISION ULTRASONIC CORROSION RATE MONITORING - The invention relates to very precisely measuring changes in thickness of pipe walls to determine corrosion rate prior to any significant corrosion loss. The thickness is determined by ultrasonic testing where many measurements of the wall thickness are taken at the same spot by a fixed sensor and errors associated with noise and temperature changes are substantially eliminated. A highly sensitive receiver converts each reflected pulse to waves that are averaged with other pulse measurements. The resulting average wave is analyzed so that each waveform is analyzed to identify the extrema and inflection points of each reflected pulse. The resulting analysis provides a far more accurate determination of the time between reflected pulses. As a result, a far more accurate picture of corrosion at the location of the wall of the pipe can be determined within weeks with a high degree of confidence. | 03-24-2011 |

20120043108 | HIGH VOLTAGE DC TETHER - A high voltage direct current (DC) tether for an airborne wind turbine has a reduced weight compared to conventional tethers. The weight reduction is achieved by using one conductor in the center of the feeder and the shielding of the feeder as a second conductor. A mechanical strength element is disposed in between the center conductor and the shielding. In this configuration, the mechanical strength element acts also as an insulator. The center conductor and the shielding can be made of aluminum or copper. The strength element can be a high strength fiber composite, woven such as VECTRAN® or SPECTRA®. The main weight savings are due to using the shielding for multiple purposes—as a conductor, as lightning protection and as an electromagnetic interference (EMI) effects barrier, while providing strength to the tether, and from using the mechanical strength element (VECTRAN® or SPECTRA®) as an insulator. The shielding is typically used as the return conductor. | 02-23-2012 |
