Learning the basics can ease loop tuning frustration and ensure stability. During plant operations, it seems that tuning control loops is an ongoing task, which can be a continual frustration to ...

Integrated slug-flow optimization can mitigate flow problems in a wide range of both offshore and onshore operating conditions. Slug flow is one of the most common flow states in horizontal and ...

Control valves experience significant reaction loads when they regulate choked flow. The highly restrictive, complex flow path of existing severe-service valves dissipates the forces from ...

It takes a large number of control valves to run a power plant, and while some valves are more critical to plant operations than others, it always follows that when a severe service valve fails, the ...

Oil field operators can use several practical equations for calculating flow rates of natural gas through venturi gas-lift valves. For critical flow, this analysis derived such equations from a ...

It is easy to take valves for granted. They have been used since the days of the Roman Empire and designs are pretty routine, so people tend to assume that a standard valve will do the job. But that ...

Piezo elements are electromechanical transducers that convert mechanical forces (pressure, tensile stress or acceleration) into voltages. The inverse piezoelectric effect, precisely the opposite, ...
