New, Laser-Based Natural Gas Moisture Analyzer Provides 'Maintenance-Free' Accuracy at Williston Basin Interstate Pipeline

(ContentDesk) May 9, 2006 -- Looking at the new moisture analyzer technology, the gas measurement engineers at Williston Basin Interstate Pipeline (WBIP) could see the potential savings in replacing their aluminum oxide probes with a new, laser-based type of moisture analyzer. So, we ran the numbers, and it appeared that we could save on the costs of refurbishing or replacing probes, as well as the considerable labor on the part of field technicians, says measurement engineer Nate Hagerott.WBIP provides natural gas transportation and underground storage to customers throughout the upper Midwest. As a subsidiary of MDU Resources Group, Inc., the company provides services to utilities, natural gas production companies, energy marketing firms and large industrial consumers.Hagerott, who works at WBIPs Montana operations, says they purchased a SpectraSensors gas analyzer in 2005 to find out if the new technology could provide the consistent accuracy that would make it trustworthy in the field.For the first few months we compared the laser-based natural gas analyzer with the Bureau of Mines chilled mirror hygrometer, he says. The readings were consistently within 1/10 pound. We have since found it unnecessary to compare it as often as we did at first, because we know that we can trust the readings.Accurate and trustworthy performance is essential to a business whose flow of pipeline-quality gas depends on it.

For this reason, engineers often wait for years to be sure that new natural gas sensor technologies have been debugged before even evaluating them.But Hagerott saw a real need for the SpectraSensors technology, enough to easily justify the cost and evaluation effort.We install moisture analyzers downstream of processing, including dehydration, he explains. When glycol carryover coats our natural gas sensor probes in addition to other contaminates, which happens over time, they tend to start giving erratic readings. Our field technicians know when that happens, so they have to replace the probe. The technician then sends the probe to the shop to be refurbished, or replaced if necessary. And if we dont have a replacement probe available, then a technician has to go out and take readings with a portable analyzer.

All of that can get pretty expensive.Using a tunable-diode laser-based technology, the SpectraSensors natural gas analyzer accurately measures and monitors moisture content by precisely measuring the absorbance of light by moisture molecules, thereby measuring the exact amount of water (or carbon dioxide). There are no chemical conversions involved, and no natural gas sensor contact with the sample gas. This eliminates coating problems, erratic measurements, and exceeded tariffs.Hagerott says the new moisture analyzer has proved the technology so well that his WBIP operation installed a second unit earlier this year. Other pipeline operators are using the new moisture analyzer technology, too. Their goals vary from saving on maintenance and labor costs to ensuring that moisture does not cause customer complaints or dangerous pipeline corrosion.

The new laser-based technology precludes such problems through parts-per billion accuracy and through measurement intervals as frequent as every second, as opposed to the 10-12 minutes between readings typical of contaminant-vulnerable quartz crystal and electrochemical sensors.For More Information Contact:George M.

Laser-Based Natural Gas Sensors: Can the Natural Gas Industry Afford To Be Without This Advanced Technology?

(ContentDesk) February 8, 2006 -- Until recently, natural gas producers, processors and distributors have relied on direct contact, surface-based electrochemical and crystal sensors for measurement of moisture in gas. However, these natural gas sensors are often highly unreliable, producing false data that can result in contaminated gas getting through lines and causing system disruptions as well as potentially hazardous conditions.Now there is a far more advanced and trustworthy monitoring technology available to natural gas producers, pipeline operators and distributors -- a tunable diode laser (TDL)-based technology developed at NASAs Jet Propulsion Laboratory at Caltech that is highly effective in detection of contaminants in natural gas. SpectraSensors,...

Combining the Newest Non-Surgical Procedures Gives Patients Maximum Rejuvenation with Minimum Recovery

Los Angeles, CA
May 31, 2005 -- Two of the most exciting and groundbreaking procedures to hit the Anti-Aging scene are now being administered in combination at Marina Plastic Surgery, a Southern California medical center focusing on rejuvenation and cosmetic enhancement. Fraxel, a nonablative laser treatment that improves skin texture, tone and coloration and ThermaCool, a "face-lift" treatment that uses radio frequencies instead of incisions to tighten skin and revitalize faces, are now being offered together to achieve synergistic benefits.On their own, these treatments harness the latest advancements in light- and radio-energy aided facial rejuvenation. Not only do the procedures provide excellent results, neither requires traditional surgery. There are no incisions, no sutures, and no long recovery periods. Both treatments target mid-level and deep skin layers to stimulate collagen regeneration, tightening slack skin, smoothing wrinkles, improving skin tone and minimizing...
