The individual composition of polycyclic aromatic hydrocarbons has been studied in high boiling (340–590°) fractions of Norio oil (wells 200, 201) which are characterized by high content of aromatic hydrocarbons and high intensity fluorescence. The eluates obtained by adsorption fractionation of aromatic hydrocarbons separated by aniline and concentrates of their crystalline components have been studied by GC, MS and GC-MS methods. For analysis of the obtained data an automated system of mass deconvolution and identification (AMDIS) was used. In the eluates under investigation the following structures were identified: indenes, tetralines, dinaphtilbenzenes, naphthalenes, fluorenes, phenantrenes, antracenes, mono- and polyalkyl derivatives ofnaphtofluorene and phenantrene, and terpeniles. In crystal samples of the eluates the banzantracene, chrizene, their methyl-, dimethyl and trymethylanaloges, phenantrene derivatives, antracenes and pyrenes were identified. The heterocyclic analogues of polycyclic aromatic hydrocarbons likemethylbenzoanthracenes, benzonaphthothiophenes, benzocarbazoles and dibenzthiophene were identified in Georgian oils for the first time.

Power Recovery

This paper pertains specifically to refinery fluid catalytic cracking and associated power-recovery concepts. The several systems described go beyond basic onsite FCC practices previously used. However, no special technical development or prototypes would be required to engineer practical and successful installations. All component equipment and apparatus reflect current state-of-the-art, requiring only explicit economic justification. The individual systems, as presented, are solely conceptual, but sufficient detail is provided to confirm their technical feasibility. Application economics will depend on geographic location, site conditions and the specific process installation.

Individual Composition

This article revisits the concept of the dividual, taking as a starting point Deleuze’s diagnosis about the relevance that dividual practices have gained with the advent of biotechnology and digital culture. Although we agree with this diagnosis, we highlight the intersections between the dividual and the individual both in Modernity and in the present time. The contemporary dividual is in tension with the modern individual, but not as a substitution, division or duplication of the individual. Rather, we state a complex dividual-individual composition, focusing on biotechnologies, digital culture and financial capitalism. Following a Foucauldian approach, we understand this composition as a result of technologies of power and the result of certain modes of subjectivation. In dialogue with Simondon’s theory of individuation, we suggest that the dividual takes part in a new mode of subjectivation which can be named a ‘dividuation’ in the context of technologically mediated experiences.

The paper discusses a method for obtaining a matrix of individual and group composition of a hydrotreated heavy gasoline fraction in industrial conditions based on the fractional composition obtained by the distillation method according to the ASTM D86 (the Russian analogue of such a standard is GOST 2177). A method for bounds estimation of the retention index (RI) change is considered on the basis of the symmetry of the RI change range relative to its arithmetic mean. Implementation of this method is performed by simulation of individual composition of C6–C12 feedstock of the catalytic reforming unit in the software package. For this purpose, the boiling curve of individual composition of hydrocarbon mixture is converted into the corresponding curve of fractional composition. The presented technique of creating a virtual soft sensor makes it possible to establish a correct relationship between the fractional composition and the individual hydrocarbon composition obtained according to the IFP 9301 (GOST R 52714) (Russian GOST R 52714 and international IFP 9301 standards for the determination of individual and group composition of hydrocarbon mixtures by capillary gas chromatography). The virtual soft sensor is based on chemical and mathematical principles. The application of this technique on the data of a real oil refinery is shown. Obtaining accurate data by means of a virtual soft sensor on the individual composition of feedstock will make it possible to optimize the catalytic reforming process and thus indirectly improve its environmental friendliness and enrichment efficiency.

The paper discusses in detail the items from the female burial of mound 6, Taksai-1 burial site, located in the West Kazakhstan Region, Terektinsky District, near the village Dolinnoe. A complex architectural gravestone structure, an accompanying rite of burial with the use of fire, the presence of rich clothing with various decorations, a complex of specific objects found in the pit, testify to the special status of the buried. All archaeological materials from the central pit of mound 6 performed a certain role in the life of the early nomads, composing a complex of ritual things for performing special rites. The functional significance of all the artifacts identified in the grave emphasizes the relation of the buried to the priestly class. In scientific literature there is no consensus about the existence of the priesthood as a profession in ancient times, but the early nomads revered the cult of a woman - the ancestor, and the priestesses were guides, keepers of the fire, the Sun, revered the goddess responsible for fertility. The burials of rich priestesses are distinguished by their special pomp of funeral ritual, the presence of gold jewelry and the individual composition of the inventory. All these characteristics are traced in mound 6 of Taksai-1 burial, it is a cult monument confirming the existence of a special priestly status in a social organization of the nomadic society.
