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.

5 Critical Steps to Prevent Pipeline Corrosion

Posted by Lance Witt on 8/5/19 8:00 AM

Corrosion monitoring and mitigation is essential for ensuring safe operation and reliable natural gas supplies. In fact, corrosion control practices could save up to $875 billion annually. And this doesn’t include the additional safety, operational and environmental benefits that come from corrosion-free equipment.

What You Need to Know About Sampling Oil Sands

Posted by Israel Gamboa on 6/5/19 8:17 AM

Every day, the world uses about 93 million barrels of crude oil, a demand that rose by 1.3% in 2018 and is soon expected to reach 99 barrels per day or more.

Oil sands mining is one method that oil producers are using to meet this demand. Although oil sands mining represents just a small percentage of crude oil production, it’s predicted that it will produce 3.7 million barrels per day by 2021. As this production increases, so will the need for accurate and efficient sampling processes.

Cool it Down with Sample Coolers

Posted by Kevin Kirst on 3/25/19 8:00 AM

Plants and facilities of all kinds use sample coolers to cool a sample from a process stream. Cooling samples as part of your steam and water sampling system is essential to maintaining safety and the representativeness of the sample.

For example, if a sample in a power plant is too hot to handle, the operator might throttle the flow to unacceptably low levels, which means the sample is no longer representative or acceptable.

Another example comes from Hydrocarbon processing or Process Analytics. Cooling the process to handle the sample is necessary.   If you take a grab sample of a certain hydrocarbon whether it be of a liquid or a gas, the safest way is to handle the sample at below 140F.  This protects the operator when handling hot samples that need to be physically taken to the lab safely for analysis.   

In order to achieve accurate data, the Electric Power Research Institute (EPRI), ASTM and ASME recommend cooling water samples to 77°F (25°C) to ensure consistent, accurate test results.

Why Small Things Like Sample Bottle Caps Are Big Things In A Hydrocarbon Processing Plant

Posted by Derek Lindsay on 10/9/18 9:27 AM

 

Sampling in a hydrocarbon processing plant has its hazards. Tapping into a process line to extract a representative sample requires careful planning, specialized equipment and a partnership with the right hydrocarbon service team. Commonly, however, more focus is spent on the best and safest way to extract the sample, than the method to seal the sample collection bottle. That can be just as hazardous.
