Known as the Rotary Drag valve, the new device represents a major step forward in valve engineering because it combines the best features of ball valves and control valves. Developers of the product ...

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 ...

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 ...

In process flow control, there are many factors affecting variability, but the greatest contributor is the control valve’s performance. Issues associated with control valves, such as dead band, ...

The SLA5800 Series Biotech and the SLAMf Series Biotech are two new mass flow controller (MFC) models from Brooks Instrument designed specifically for improved gas flow control in biotechnology ...

We report the design, fabrication and characterization of a microelectromechanical systems (MEMS) flow control device for gas chromatography (GC) with the capability of sustaining high-temperature ...

Industrial emissions, automobile exhaust and household waste produce a wide range of pollutants. These include chemical gases such as NOx as well as fluorocarbons. Together with CO 2 and methane, they ...

New research has improved control of slack line flow in steep slope liquids pipelines, whether during commissioning, steady operations, or in the wake of an accident. New research has improved control ...
