What are the steps to finding the best pressure sensor for a particular application? That’s a challenge faced by many a young engineer just out of school. Engineering school teaches a great deal of theory, but what is the best way to choose when so many things that affect the decision are not obvious, and not necessarily part of the formal curriculum? This article reviews a series of questions and...

Pressure transmitters are widely used throughout the chemical process industries (CPI). Although pressure in and of itself is an important process parameter, differential pressure (DP) measurements enable the inference of other important parameters as well. This article presents a concise overview of how DP transmitters can be put to work in CPI plants.   Definitions Here are some important common...

Pressure-relief solutions are commonly used in the chemical process industries (CPI) to ensure safe working environments for personnel and to protect equipment and assets. Relief valves (RV) and rupture discs (RD) are the most commonly used pressure-safety devices and are generally specified and selected according to application-specific requirements. For pressure-system designers looking for viable...

Pressure-relief valves are widely and effectively used in situations where the pressure in a process vessel rises to above the vessel’s design-pressure rating. Proper relief-valve sizing is critical to plant and process safety to permit fluids sufficient flow area to exit the vessel. Sizing relief valves requires several equations for different flows (liquid flow, vapor flow and two-phase flow), as...

How to utilize a pipeline inspection gauge (pig) in a crude-oil pipeline that requires a pressure control valve can be a bewildering question for process engineers, especially in cases where the oil pipeline does not have any pig-launcher and receiver facilities. The challenge becomes how to keep the pressure profile unchanged along the length of the pipeline. This task is complicated when the pipeline...
