Abstract A refining column in the middle east that started its official production in 2020 provides its sour wastewater from all refinery plants to two sour water units (SWS1 and SWS2) to strip H2S and NH3.Sour gas from the refinery uses a lean amine solution for gas sweetening to absorb H2S in different absorbers.Rich amine with H2S is then stripp
Irrigation pumping is a major expense of agricultural operations, especially in arid/semi-arid areas that extract large amounts of water from deep groundwater resources.Studying and improving pumping efficiencies can have direct impacts on farm net profits and on the amount of greenhouse gases (GHG) emitted from pumping plants.In Minerals for Kids
A racemic mixture of the title compound, C26H26Br2, a brominated [4]helicene, crystallizes, forming columns of stacked molecules.There are two crystallographically unique molecules in the asymmetric unit, both with the same helical handedness.As is typical EMF products with helicene congeners, the unique molecules show short interatomic contacts be
The study of effective approaches to the development of sports tourism is an extremely relevant issue for a number of developed countries, including Kazakhstan.The purpose of this study is to analyse effective means and mechanisms affecting the development of sports tourism in Kazakhstan, in particular, in the context of rock climbing.Based on this
A thorough understanding of fundamental limits of wireless-powered unmanned aerial vehicle (UAV) relay networks in millimeter waves is still missing.We narrow this gap by investigating the outage performance of a UAV-assisted wireless network over fluctuating two-ray (FTR) channels.The FTR fading model is particularly appealing since well character
