Ultrasonic Metering, Creative Insulation Engineering, Aid LNG Plant

February 2016, Vol. 243, No. 2

A major East Coast storage facility for liquefied natural gas (LNG) had a flow metering challenge on one line.  The problem was directly related to the temperature of the product. LNG is liquefied to concentrate its volume for shipping and, as a result, the temperature of the liquid drops to a cryogenic minus 265 degrees Fahrenheit, which must be maintained throughout the storage facility and delivery system. Challenges of LNG Storage With the introduction of fracking for natural gas in the U.S. and the subsequent drop in prices, LNG storage facilities which import gas have […]

New View on Oil and Gas Facilities

February 2016, Vol. 243, No. 2

Spatial information – an object’s location, size, shape and relationship to other structures and objects – is an essential component in planning, constructing and operating energy facilities. In order to support efficient production and transport of oil and gas, energy producers must have accurate, timely information about structures, pipelines and other operating assets. Various forms of spatial data, ranging from 2-D maps and schematics to 3-D drawings, have long been familiar tools for engineers and plant operators. But gathering spatial information with sufficient accuracy and detail can be costly and time-consuming. Headquartered in Denver, CH2M […]

Measuring Methane Emissions: Part of Gas Pipelines’ Future

January 2016, Vol. 243, No. 1

When examining the growing cottage industry of methane emissions control, it is clear upfront that it is one of the toughest sub-specialties in the emerging conglomerate that makes up the national response to climate change impacts. Researchers, engineers and public-policy wonks must start with the reality that methane coming out of the ground is odorless, invisible and a powerful greenhouse gas (GHG). And that’s the easy part. Prompted first by operators seeking efficiencies and greater economic value, and more recently by federal government initiatives, the unrelenting effort to curb methane emissions has covered all corners […]

Mr. Mayeaux, You Left Your Company in the Right Hands

December 2015 Vol. 242, No. 12

Justin Harvey knows he has an industrial-sized pair of shoes to fill as he takes the helm at A+ Corporation, a family-owned and operated gas sample conditioning system service company in Gonzales, LA.

The 30-year-old Harvey was just a toddler when his legendary grandfather Donald Mayeaux founded the company in 1989. Mayeaux earned his reputation for developing product concepts that changed the manner in which natural gas was sampled.

EPA Proposes New Methane Regulations for Midstream Operations

December 2015 Vol. 242, No. 12

The federal Environmental Protection Agency recently proposed new regulations for methane and volatile organic compound (VOC) emissions from the oil and gas sector that place time-consuming and expensive new requirements on midstream businesses.

These regulations would not apply to pipelines, but would require ongoing emissions monitoring and equipment replacements at compressor stations and natural gas processing plants built, “modified,” or “reconstructed” after Sept. 18, 2015.

Inline Services

Inline’s polyurethane spheres are ideal for removing liquids from wet gas systems, product separation, hydrostatic line testing and wax control in crude oil pipelines. Our spheres are manufactured of high quality polyurethane for lasting service in the worst conditions. Inflatable spheres, 12-inch and larger are designed with two filling holes to ensure complete removal of the air inside the sphere. Spheres can also be manufactured out of medium and hard-density foam, coated in various polyurethane coatings and even equipped with brushes. www.inlineservices.com

Data Shows Most Crude Produced in Lower 48 Light Oils

U.S. Energy Information Administration (EIA) data show that for the first nine months of 2015, most (50.8%) of the crude oil produced in the Lower 48 states were light oils with an API gravity above 40 degrees. The largest share of production was in the 40.1 to 45 degree API gravity range.

Retrofitting Customized Valves, Actuators for Pipeline Monitoring Stations

November 2015, Vol. 242, No. 11

Oil and gas engineers face a major problem in accurately and reliably measuring and monitoring the various fluids that are introduced into oil pipelines from well site pumping stations. A thorough understanding of both the oil separation process and the properties of valves and actuators is required to correctly specify a system that will sufficiently measure and monitor these various types of fluids. Also, the conditions downstream from each well are different, requiring valves and actuators to be highly customized to their specific role in the process.

Mastering Inspection of Challenging Pipelines

November 2015, Vol. 242, No. 11

Any inspection device used internally must be introduced into the pipeline to be investigated. This implies that the line is accessible. “Piggable” lines need suitable launchers and receivers and are generally inspected in a unidirectional mode. If tool traps are not available or suitable, access has to be achieved via other means. Accessibility can be achieved through technical and/or procedural means.
