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 ...

A new leaf imaging system lets scientists watch plant stomata control water loss and carbon uptake in real time.

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 ...

A new empirical correlation can help engineers size chokes for controlling gas-condensate production and predicting the performance of flowing wells under different conditions. The correlation was ...

Know your options when selecting the appropriate flowmeter technology to measure natural gas, water, and steam in power generation. In many chemical plants, the electricity the plant uses is derived ...

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 ...

I'm not joking." He may not have been joking, but we failed to find convincing evidence that wood pipes carry natural gas in the U.S. today. Wood did have a place in the history of natural gas ...

On the eve of a European Union meeting to debate a gas conservation plan to make the bloc less vulnerable to a Russian squeeze, Moscow slashed the flow to Germany. By Melissa Eddy and Matina ...
