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 sampling application experts. 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.

Five Things to Know When Sampling in a Hydrocarbon Processing Plant

Posted by Sentry Equipment on 8/1/18 8:35 AM

Sampling within the hydrocarbon process is essential for gaining visibility into product quality, identifying corrosion and ensuring processes are operating as expected. It occurs at multiple points across virtually every stage of hydrocarbon processing. However, are you giving sampling the attention it needs?

What to Know About Drip Pots and Corrosion Monitoring

Posted by Kevin Kirst on 3/22/17 10:30 AM

Internal metal corrosion in hazardous liquid, gas transmission and gas-gathering applications is inevitable and continues to cause leaks and catastrophic failures. Due to the fact that internal corrosion is time dependent, the number of incidents could be increasing due to aging pipeline infrastructure. Such disasters can damage the environment and cause costly downtime and waste in pipeline productivity – in addition to astronomical cleanup costs.

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.
