Pneumatic instrument systems powered by high-pressure natural gas are often used across the natural gas and petroleum industries for process control. Typical process control applications include pressure, temperature, liquid level, and flow rate regulation. The constant bleed of natural gas from these controllers is collectively one of the largest sources of methane emissions in the natural gas...

The Twister supersonic separator is a unique combination of known physical processes, combining aerodynamics, thermodynamics and fluid dynamics to produce an innovative gas conditioning process. Condensation and separation at supersonic velocity is the key for achieving a significant reduction in both capital and operating cost. Twister is a proven gas conditioning technology. Condensation and ...

multiphase impeller stirred tank reactors enhance mixing of reacting species used in a variety of chemical industries. these reactors have been studied based on computational fluid dynamics (cfd) that can be used in the analysis, design and scale up of these reactors. most of the researches done in this area are limited to single phase reactors, and a few remaining two phase flow investigations...

Liquid transportation fuels derived from coal and natural gas could helpthe United States reduce its dependence on petroleum. The fuels could be produced domestically or imported from fossil fuel-rich countries. The goal of this paper is to determine the life-cycle GHG emissions of coal- and natural gas-based Fischer-Tropsch (FT) liquids, as well as to compare production costs. The results show...

Due to increasing economic pressures in natural gas production, there is a recognized demand for flow meters that are able to measure when a significant quantity of liquid is present in gas flows. The key issues are that the liquid quantity is often unknown and its presence can affect the operation of traditional dry gas meters making the gas flow readings inaccurate. A number of techniques are...

we are tackling energy and environment-related challenges through collaboration, innovation, and multidisciplinary problem solving. Here are some recent examples: NATURAL GAS ENGINEERING Converting methane gas to liquid fuel Venkat Viswanathan

Acoustic properties of polymeric liquids are high sensitive to free gas traces in the form of fine bubbles. Their presence is typical for such liquids because of chemical reactions, small wettability of solid boundaries, trapping of air in technological operations, etc. Liquid temperature influences essentially its rheological properties, which may have an impact on the bubble pulsations and so...

Superadiabatic Partial Oxidation for Hydrogen and Sulfur Production from Hydrogen Sulfide The Gas Technology Institute has been investigating superadiabatic partial oxidation concepts to not only develop novel, cost-effective processes to recover hydrogen and sulfur from hydrogen sulfide, but also produce hydrogen from natural gas and other liquid hydrocarbons, and gasify solid feedstocks, incl...
