Supercritical Fluids (SCFs) have unique thermophyscial properties and heat-transfer characteristics, which make them very attractive for use in power industry. In this chapter, specifics of thermophysical properties and heat transfer of SCFs such as water, carbon dioxide, and helium are considered and discussed. Also, particularities of heat transfer at Supercritical Pressures (SCPs) are presented, and the most accurate heat-transfer correlations are listed. Supercritical Water (SCW) is widely used as the working fluid in the SCP Rankine “steam”-turbine cycle in fossil-fuel thermal power plants. This increase in thermal efficiency is possible by application of high-temperature reactors and power cycles. Currently, six concepts of Generation-IV reactors are being developed, with coolant outlet temperatures of 500°C~1000°C. SCFs will be used as coolants (helium in GFRs and VHTRs, and SCW in SCWRs) and/or working fluids in power cycles (helium, mixture of nitrogen (80%) and helium (20%), nitrogen and carbon dioxide in Brayton gas-turbine cycles, and SCW/“steam” in Rankine cycle).

Over the time, oil companies, utilities, and the Bush administration have come around to the idea that global warming is real and a consortium of USA. Companies including PG&E, Duke Energy, and Alcoa- has reportedly asked for congressional action to control carbon emissions. The chart presented in the article shows in detail the carbon dioxide emitted across the entire US economy, as determined by a draft report of the USA. Environmental Protection Agency released in February. Each square represents 10 million tons of carbon dioxide emissions and there are 726 of them. A quick glance shows that massive amounts of carbon dioxide are produced from the burning of coal in thermal power plants and the burning of gasoline and diesel fuel in the engines of cars and trucks. Switzerland, Sweden, Japan, and France are considered as models of Western society. They owe their position to a few factors, some of which may be emulated, and some of which are geographical accidents.

Vegetation Indexes

Using the Emissions Database for Global Atmospheric Research satellite data on the annual global carbon dioxide emissions, their distributions in the Donbass were obtained for the period from 2013 to 2018, indicating their main anthropogenic sources: large cities, thermal power plants and metallurgical plants. Control points were selected near and far from the largest sources of carbon dioxide emissions and, with the help of the resources of the Shared Use Center, systems for archiving, processing and analysis of satellite data of the Institute of Space Research of the Russian Academy of Sciences, the average annual vegetation indexes in the territory of Donbass and at control points for the same period of time were determined. A comparison was made of the reflection intensities in the near infrared and red regions of the spectrum, as well as the normalized relative vegetation indexes at these control points. It is indicated that there is no direct correlation between the values of vegetation indexes and the concentration of carbon dioxide in a given period of time. A sharp decrease in the volume of biomass was noted in a number of control points due to the appearance of signs of drought in the Black Sea region, as well as a significant increase in wild vegetation in the conflict zone in the eastern regions of Donbass.
