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 ...

Gas chromatography is widely used for monitoring chemical reactions, industrial processes, and volatile compounds, but ...

A novel approach using computational fluid dynamics techniques provides a way for determining the characteristics of gas passing through a gas-lift valve. In the method, CFD calculations numerically ...

As today's science and engineering focuses more and more on micro technology, the requirement to be able to measure and control extremely low gas mass flow rates has become very important. With ...

A single power plant uses hundreds of valves to control almost every aspect of its operation. Valves, in conjunction with a controlling actuator, are used for pollution control, feed water, cooling ...

• The first step in selecting a valve is determining its function. • Review Cv or pressure drop when considering one valve versus another. • Don’t overlook maintenance requirements when specifying a ...
