Replacing coal with natural gas has contributed to recent emissions reductions in the electric sector, but there are questions about the near- and long-term roles for gas under deep decarbonization. In this study, we assess the potential role for natural gas and carbon removal in deeply decarbon...
Gas transport through nanochannels is a widespread phenomenon in nature and plays an essential role in various industrial fields, including membrane separation1,2, gas extraction3,4, nano catalysis5and vacuum technology6,7. In the regime of free molecular flow, the continuum theory breaks down and...
There are three types of matter ：Solid，Liquid and Gas Definition（定义）:Solid(s):has a ___（确定的） shape and___（体积） but cannot ___（流动）Liquid(l):has a definite volume but take the shapes of it ___（容器）,___(能够) flow。Gas(g):has not definite shape or volume ...
But, once the investment has been made, the costs of moving an LNG carrier are relatively low since so much natural gas can be transported in a small volume and the ‘boil-off’ gas used for autorefrigeration (see below) can also be used as a tanker fuel, which is why LNG becomes ...
The gas stored in an UGS is called the inventory, and is classified as either cushion gas, which is to maintain adequate pressure, or working gas, which is the maximum volume of gas available for withdrawal. The international UGS technology in Europe has evolved with quite a long history, ...
The shape and the size of the obstacle, and the gas concentration, were adjusted in the experiments. It can be seen from the experimental results that, instead of being accelerated, the flame propagation inside the explosion vessel is decelerated by the plate obstacles fixed at the bottom of ...
Generally this independent double membrane gasholder is a 3/4 sphere, made of special processed polyester material and fixed on the cement foundation by rails. Divided into outer membrane, inner membrane and bottom membrane, the outer membrane is always pressurized to form the sha...

comprises two hemispherical electrodes made of stainless steel and fixed towards a cylindrical PEEK housing (housing 3). The resulting dimensions of the DMS cell were 30 × 10 × 1.0 mm (length × width × gap height). The DMS device was fixed onto a 3D translation stage, and then ...
while resistivity logging has a general response to fractures; In layers with more developed fractures, natural gamma values are mostly higher than 40API, rock volume density is less than 2.8 g/cm3, neutron porosity is greater than 12.5%, and acoustic time difference is greater than 160 μ s...
