Reliable and accurate sampling system for natural gas applications

NG plant with measuring lines shows reliable and accurate sampling system for LNG applications.

My previous article in this series explained what are the main issues in obtaining a representative sample in NG applications.

This case study demonstrates a reliable sampling solution currently used by plant operators. It helps plant operators to obtain representative samples.

What are the main issues in obtaining a representative sample in NG applications?

NG plant with measuring lines shows issues in obtaining representative sample.

In this article, I present the major issues associated with obtaining a representative sample in NG applications. The article explains what is representative sampling, and why sampling is important in the natural gas industry. I discuss factors that determine what should be a suitable sampling frequency in a process, and which sampling standards can be followed to ensure representative sampling.

Several major issues in obtaining a representative sample, and common design flaws that lead to poor sampling are presented and discussed. In addition, I present how a suitable probe length can be determined and how the probe should be installed. The different types of commonly used sampling probes are also compared and discussed.
