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.

How to avoid hydrate formation during underground natural gas storage in salt caverns

3d image of natural gas storage in salt caverns and how to avoid hydrate formation.

In this case study, I focus on how to avoid hydrate formation in natural gas pressure measurement pipelines. I describe the traditional approach to avoid hydrate formation during natural gas storage in salt caverns. Furthermore, I explain a patented customer solution that AS-Schneider has industrialized.

Underground natural gas storage in salt caverns and the challenge of hydrate formation

3d image of natural gas storage in salt caverns and the challenge of hydrate formation.

Many of my customers use natural gas storage facilities in order to balance out low and peak demands over the course of a year.
Over the years, I have gained a lot of valuable experience on this topic. This knowledge is what I would like to share with you in the context of a blog article.

4 most important mechanical isolation methods of process piping & equipment

Oil and gas plant with closed and locked valve shawing different isolation methods.

Positive isolation is the isolation of process piping, equipment, or vessels from hazardous materials such that it is impossible for the material to enter the work area. Positive isolation must remove all risk of accidental reconnection to the source of the hazard due to equipment failure or operator error. There are several methods of achieving positive isolation some of which are discussed below.

5 important facts for a safe and transparent (remote) third-party inspection

Safe and transparent through your third-party inspection (remote inspection).

We are all facing many restrictions due to the pandemic. Therefore, we need to find ways to still provide the best possible support to our customers. One digital service that our customers can use is our third party inspections – better said remote inspections.
Our customers can use the remote visual inspection to check the valve quality before shipping.

High pressure valves up to 15,000 psi in offshore application

Offshore platform with high pressure valves up to 15,000 psi.

We all know, pressure is one of the most important process parameters, in the field of measurement and control. Pressure measurement under extreme applications are done for enormously high-pressure range. These measurements must be safe and precise, for which we need reliable valves to maintain tight control and regulation at these high pressures.
