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 ...

Precisely formulated gas mixtures with known concentrations of particular target gases are referred to as calibration gas standards. To guarantee the accuracy of gas concentration measurements, almost ...

This article describes how a multivariable pressure transmitter with built-in dynamic compensation can correct for many of the errors and inaccuracies that can occur in differential pressure based ...

A compositional program in a dynamic mode simulated multiphase flow through porous media and predicted condensate formation in a gas-condensate reservoir in southern Iran’s Aghar field. The study used ...

Hydrogen has long played a key role as an industrial feedstock in petroleum refining, fertilizer production, and chemical manufacturing. However, conventional methods of producing hydrogen generate ...

Like piezoresistive, piezoelectric, and capacitive sensing techniques devices, sensors based on thermal microelectromechanical systems (MEMS) have enabled motion sensing in accelerometers. These ...

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 ...
