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.

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.

Refrigeration in Oil & Gas Industry

Refrigeration in Oil & Gas industry - Performance and environmental issues.

Requirements are not very high in the regular refrigeration market, which includes supermarkets and industrial applications. But things are different in the Petrochemical as well as Oil & Gas Industry. As an expert for industrial valves, I often notice that the demand for high-quality valves has increased significantly in these industries. But what is the reason? Let`s find it out!
