“…In works [51,52], it is noted that, in terms of the energy input, using a compressor is First, the liquid carbon dioxide CO 2 is cooled down to zero temperatures and fed to a pump or compressor. By strongly compressing above 31 MPa, the CO 2 is simultaneously heated and converted into a supercritical state.…”

The unique properties of supercritical fluid technology have found wide application in various industry sectors. Supercritical fluids allow for the obtainment of new types of products with special characteristics, or development and design of technological processes that are cost-effective and friendly to the environment. One of the promising areas where supercritical fluids, especially carbon dioxide, can be used is the oil industry. In this regard, the present review article summarizes the results of theoretical and experimental studies of the use of supercritical fluids in the oil and gas industry for supercritical extraction in the course of oil refining, increasing oil recovery in the production of heavy oil, hydraulic fracturing, as well as processing and disposal of oil sludge and asphaltenes. At the end of the present review, the issue of the impact of supercritical fluid on the corrosion of oil and gas equipment is considered. It is found that supercritical fluid technologies are very promising for the oil industry, but supercritical fluids also have disadvantages, such as expansion or incompatibility with materials (for example, rubber).

“…In works [51,52], it is noted that, in terms of the energy input, using a compressor is more expensive than using a pump. In the case of the pump, condensation has a greater impact, while in the case of the compressor, the electricity required to operate the compressor is more expensive (Figure 5).…”

“…To study, refine, and expand the classical notions of solubility, a significant research space has been formed [7]. Among the notions to consider are the limits of applicability of the conventional notions of solubility under SCF conditions for some types of phase equilibria in solute-solvent systems, the crossover behavior of the solubility isotherms of solutes in SCF solvents [7], the comparative efficiency of extraction processes with the liquid-phase and supercritical fluid states of extractants for various types of phase equilibria in solute-solvent systems [3], the development of new methods to describe and generalize experimental data on solubility with the search of predictive capabilities within the subject under discussion [7,8], and the investigation of the efficiency of using SCF solvents of another physicochemical nature (other than widely used CO 2 and H 2 O) [9][10][11].…”

The extraction of valuable components (methyl phenyl carbinol, acetophenone, ethylbenzene, phenol, propylene glycol) from industrial wastewater formed during styrene-propylene oxide coproduction by the hydroperoxide method at PAO Nizhnekamskneftekhim was used as an example to formulate and discuss approaches to increasing the efficiency of the extraction process performed under supercritical fluid conditions beyond the binodal for the systems desired component-extractant with type I and II phase behavior. The assumptions were experimentally confirmed by studying the extraction of methyl phenyl carbinol and phenol from their aqueous solutions with such extractants as carbon dioxide in the liquid and supercritical fluid state and also a supercritical propane/butane mixture. The phase equilibrium of the thermodynamic system propane/butane-propylene glycol was experimentally investigated at 403, 423, and 443 K.
