Formed by the same processes that formed oil, natural gas is often found at the top of oil deposits. The most voluminous natural gas reservoirs occur in Cretaceous strata. Land use changes caused by exploration and extraction of natural gas produce the same biodiversity impacts described for oil...
Considering that a student knows the four properties that describe a gas, give some laboratory situations or chemistry problems where she could use them. Gas: Gas is one of the most vital states of the matter. In the gas...
Understanding water saturation levels in tight gas carbonate reservoirs is vital for optimizing hydrocarbon production and mitigating challenges such as reduced permeability due to water saturation (Sw) and pore throat blockages, given its critical role in managing capillary pressure in water drive mechani...
Haldor Topsøe's proprietary, in-house process model is described in Refs. [30, 51]. The parameters in this model were determined by experiments in a full-size monotube reformer PDU (Fig. 21) [4, 51] and validated against a large amount of industrial data. Sign in to download full-...
Connecting chemical properties to various wine characteristics is of great interest to the science of olfaction as well as the wine industry. We explored whether Bordeaux wine chemical identities and vintages (harvest year) can be inferred from a common and affordable chemical analysis, namely, a co...
How is the Van der Waals equation an improvement over the ideal gas equation? How are the a and b parameters related to molecular properties of the gas? Which assumption(s) of the kinetic-molecular theory explain the behavior of gases described by Boyl...
an increase of graphene’s resistance. Figure13demonstrates a general progress of gas sensing, which has been described above. This is the old and universal theory called “Oxygen anion barrier model,” which used to illustrate the mechanism of gas-sensing progress based on metal-oxide ...
Each interaction between particle “a” and “b” can be described by the mean free path λab, the average distance the particles “a” travel between collisions within the group of particles “b”. The mean free path is given by, (1)λab=1σabnb where σab is the cross section of ...
This paper presents a physics-informed neural network (PINN) approach for monitoring the health of diesel engines. The aim is to evaluate the engine dynamics, identify unknown parameters in a “mean value” model, and anticipate maintenance requirements.
Natural gas with a relatively high proportion of liquefiable heavy hydrocarbons is described as ‘wet’ or ‘rich’, while gas with a low proportion of heavy hydrocarbons, or gas that has been processed to remove liquefiable heavy hydrocarbons, is described as ‘dry’ or ‘lean’. Natural gas...
