Experimental investigation of maldistribution characteristics of gas‐liquid two-phase flow in a horizontal pipeline

open access: yesFrontiers in Earth Science, 2022
In the flow distribution of oil and gas gathering and transportation system, the flow pattern, inertia force, gravity, and other factors will lead to uneven flow distribution of each outlet pipe, which will seriously affect the economy and safety of the ...

Bats Are Natural Reservoirs of SARS-Like Coronaviruses [PDF]

open access: yesScience, 2005
Severe acute respiratory syndrome (SARS) emerged in 2002 to 2003 in southern China. The origin of its etiological agent, the SARS coronavirus (SARS-CoV), remains elusive. Here we report that species of bats are a natural host of coronaviruses closely related to those responsible for the SARS outbreak.

Study on structure optimization and applicability of hydrocyclone in natural gas hydrate exploitation

open access: yesFrontiers in Earth Science, 2022
With the development of economy and industry, the consumption of fossil energy is gradually increasing. Currently, natural gas hydrates (NGH) are considered to be an ideal alternative energy due to its large reserve and high energy density.

Alcohols for hydrate inhibition – Different alcohols and different mechanisms

open access: yesPetroleum, 2022
Methanol has been used to prevent hydrate formation in industrial handling of hydrate forming mixtures containing water for many decades. Ethanol is also used for the same purpose in countries that have easy access to low price ethanol, like for instance
