Maximize Your Low-Emission Gas and Liquid Samplers' Output

Posted by George Buss on 2/17/20 8:00 AM

Low-emission (low-e) closed loop gas and liquid sampling systems are simple, safe and accurate ways to manage representative sampling in your plant. But even the most reliable sampling solution will need ongoing maintenance and service. When your gas and liquid samplers aren’t working properly, these troubleshooting tips can keep your system running smoothly.

How to Choose Your Internal Corrosion Mitigation Method

Posted by Lance Witt on 12/9/19 8:00 AM

This is the third part in our series about preventing, monitoring and treating corrosion in hydrocarbon pipelines. You can read the first two posts here and here.

Internal corrosion monitoring is critical to preventing and addressing corrosion inside gas and oil pipelines. It’s also the first step in choosing the right corrosion mitigation method based on identified corrosive constituents.

Internal Corrosion Monitoring: What You Need to Know

Posted by Lance Witt on 11/18/19 8:00 AM

Read Part I in this series to learn about the tools used to monitor pipeline corrosion.

Pipelines carrying oil and gas experience internal corrosion when water is present inside the lines. The amount of corrosion will vary, depending on factors such as temperature, total pressure, CO2 and H2S content of the gas, pH of the water, flow conditions, use of inhibiting chemicals and more.

But no matter the amount of corrosion, it can have devastating effects on your equipment.

Common Practices to Prevent Pipeline Freeze

Posted by Bryan Stockburger on 11/4/19 8:00 AM

According to the Farmers’ Almanac, this year’s winter is predicted to be a “polar coaster” with freezing, frigid and frosty weather across two-thirds of the country. This level of extreme weather leaves midstream pipelines at risk for damage such as freezing.

Don't Let Pipeline Corrosion Get the Best of You

Posted by Lance Witt on 9/9/19 8:00 AM

Corrosion is one of the biggest threats to the petroleum industry and preventing it is especially critical in systems susceptible to producing corrosive environments, such as flow lines, transportation pipelines, vessels, water systems, boilers, vacuum towers, cooling systems, amine systems and crude oil systems.

In order to mitigate this devastating occurrence, accurate measurement and monitoring is crucial.

Repair vs. Replace: Managing Your Hydrocarbon Plant's Sampling Equipment

Posted by Randy Cruse on 8/26/19 8:00 AM

Many industrial plants in the United States were built decades ago and were not expected to still be in operation. Yet many are still running today, well past their expected life span. Within these plants, hydrocarbon sampling systems and equipment are often overlooked, even as new technology and regulations demand more from them.

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.
