this paper presents a mapping procedure for risk mapping of water and wind erosion, whichhelps to identify protective measures needed in the planning and management of natural parks. the map of water erosion risk was developed by combining the original and revised universal soil loss equation methodologies (usle-rusle), and the map of wind erosion risk was developed using quirantes’ method. usi...

The demand for liquified natural gas grows as it is an energy resource that has more flexible means of transport than non-liquefied gas, and eco-friendly other fossil fuels. This paper focused on comparing five different mixed-refrigerant liquefaction processes to determine which one the most efficient in energetic economic terms four processing scales (20,000 kg/h 2, 4, 8 MTPA feed). Simpler w...

Hydrogen energy is a crucial carrier for the growth of system and its low-carbon transformation. Using natural gas as hydrogen transport pipeline network transportation significant step toward realizing large-scale long-distance transport. Hydrogen-mixed mainly separated into by physical methods at present. High purity recovery, but recovery rate low. At same time, compared with gas, liquefied ...
