How to Effectively Sample Gas Without Surface Interactions

Posted by Marty Higgins on 2/8/17 11:00 AM

The chemical compatibility of materials used to construct analytical systems for sampling, transfer, and analysis of oil and gas must be carefully considered to maximize reliability. Specifically, virtually all natural gas samples contain sulfur compounds which need to be precisely quantified for quality purposes. In most applications, sulfur compounds like hydrogen sulfide (H2S) must be quantified at the parts-per-million (ppm) and sometimes even parts-per-billion (ppb) level.

However, the stainless steel components that typically make up a gas sampler are prone to absorbing sulfur compounds onto the surface. Though this problem may seem negligible in gas samples with a high percentage of sulfur concentrations, it is impossible to accurately quantify sulfur and other active compounds at trace levels without first treating the stainless steel flow path.

Refinery Implements Best Practices in Crude Oil Sampling

Posted by John Powalisz on 1/4/17 10:30 AM

Within the oil and gas industry, hydrocarbon liquids such as crude oil, condensates, and oil and water mixtures must be sampled to yield representative samples for analysis. The resulting data is used for quality control, to determine product properties and composition, and for fiscal calculations, allocations and loss control.

In addition to complying with custody transfer standards such as API 8.2 and ASTM D 4177, the advantages of representative sampling include:

  •  Higher return on investment
  •  Better loss control
  •  Lower operating costs

Why global manufacturers should align with internationally certified suppliers

Posted by Dan Quigley on 6/23/16 7:00 AM

As companies continue to find ways to compete globally, they are expanding their worldwide reach. Operating manufacturing plants in various countries can result in a distinct competitive advantage. However, if you are working with suppliers that are not aware of and do not meet international certifications in operations and materials, delays and product rework could cost you that competitive edge.

How a sample transport innovation protects from H2S exposure

Posted by Kevin Kirst on 5/17/16 3:36 PM

Petroleum refining is one of the largest global industries. The products produced in refineries fuel our transportation systems and are the feedstock used to produce a wide variety of petroleum-based products. Refinery operations involve processes and equipment that operate at elevated pressures and temperatures, as well as process feedstock and chemical additives detrimental to human health. Additionally, some byproducts of the processes also are hazardous to humans.

How the right corrosion monitoring solution improves safety, labor costs, efficiency

Posted by Kevin Kirst on 5/12/16 1:20 PM

Natural gas use is seasonal, especially in northern states, which depend on it for heating through the cold and snow of winter. To ensure that adequate supplies of natural gas are available during winter storms, companies that produce and distribute natural gas use large underground storage pools or fields to hold large volumes of natural gas at elevated pressures.
