Zeolite Production

The IGPC Engineering Department designed the basis technological and machine projects for a detergent zeolite complex, on the basis of which a pilot plant with an initial capacity of 5,000 t/y was constructed in 1983 within Birac-Zvornik production complex. Additional projects were done afterwards and the starting capacity increased to 200,000 t/y in 1988. This plant became the biggest producer of detergent zeolite in the world. These projects were manufactured on the basis of specific technology developed in the laboratories of the IGPC.Several goals were realized by designing a detergent zeolite production complex. This technology was an innovation, because a new approach in detergent zeolite production was developed. The product meets all quality demands, as well as environmental regulations. The detergent production process is fully automatized and the product has uniform quality. There is no waste material in detergent zeolite production, because all products with unsatisfactory quality are returned to the process. The production process can be controlled manually, which is necessary during stanrt-up, and repairs.

Zeolite Production

The IGPC Engineering Department, together with the "Birac", Zvornik Engineering Department designed basic projects for detergent zeolite production, using waste flotation sand and hydrates. Several projects were completed: technological, machine, electrical, automation. On the basis of these projects, production plant in Tallinn, Estonia was constructed, with a capacity of 100,000 t/y from 1989. to 1993. This plant became the biggest producer of detergent zeolite in the world.Several goals were realized by designing the "Ceosil" plant. Waste flotation sand was used and detergent zeolite was produced in a market which is not properly supplied with this zeolite. The product meets all quality demands, as well as environmental regulations. The detergent production process is fully automatized and the product has uniform quality. There is no waste material in detergent zeolite production, because all products with unsatisfactory quality are returned to the process. The production process can be controlled manually, which is necessary during start - up, and repairs.

Zeolite Production

The IGPC Engineering Department designed basic projects for a wet hydrate dissolution plant, using technology developed in the IGPC laboratories. Several projects were completed: technological, machine, electrical, automation. On the basis of these projects, a production plant with capacity of 50,000 t/y was manufactured, at "Zeolite Mira", Mira (VE), Italy, in 1997, for increasing detergent zeolite production from 50,000 to 100,000 t/y. Several goals were realized by designing a wet hydrate dissolution plant. Main goal was increasing the detergent zeolite production capacity. The technological cycle of NaOH was closed, and no effluents emitted, and there is no pollution. Wet hydrate dissolution is now fully continuous, which is important for maintaining zeolite production quality, as well as for simplifying production. The wet hydrate production process is fully automatized, and the product has uniform quality. The production process can be controlled manually, which is necessary during start-up, and repairs. By installing additional process equipment (centrifugal pumps and dissolving reactors) technological bottlenecks were overcome, and by adjusting NaOH tanks and dissolving reactors, the capacities of the process equipment was fully utilized.

Zeolite Production

The IGPC Engineering Department designed a basic technological project for an evaporation unit for detergent zeolite production at "Zeolite Mira", Mira, Italy. The evaporation unit was for a capacity of 15,000 t/h of evaporated water per hour from 26,000 t/h of 11 % NaOH solution.The gained product meets all quality regulation, as well as environmental regulations. The evaporation process is fully automatized, and the product has uniform quality. There is no waste material in detergent zeolite production, because all products with unsatisfactory quality are returned to the process. The production process can be controlled manually, which is necessary during start-up, and repairs. A fully closed cycle of filtrate was achieved by installing an evaporation unit. 11% NaOH solution is produced in detergent zeolite filtration, which is dangerous waste. It is evaporated to 26% NaOH solution and afterwards returned to the wet hydrate dissolution plant. In this way environmental protection is achieved, as well as a highly economical process.

The phenomenon of economic growth is studied by economists and statisticians in various aspects for a long time. Economic theory is devoted to assessing factors of growth in the tradition of R. Solow, R. Barrow, W. Easterly and others. During the last quarter of the century, however, the institutionalists, namely D. North, D. Wallis, B. Weingast as well as D. Acemoglu and J. Robinson, have shown the complexity of the problem of development on the part of socioeconomic and political institutions. As a result, solving the problem of how economic growth affects inequality between countries has proved extremely difficult. The modern world is very diverse in terms of development level, and the article offers a new approach to the formation of the idea of stylized facts using cluster analysis. The existing statistics allows to estimate on a unified basis the level of GDP production by 174 countries of the world for 1992—2016. The article presents a structured picture of the world: the distribution of countries in seven clusters, different in levels of development. During the period under review, there was a strong per capita GDP growth in PPP in the middle of the distribution, poverty in various countries declined markedly. At the same time, in 1992—2016, the difference increased not only between rich and poor groups of countries, but also between clusters.

Security Concern

As IT sector is ruling the world now,confidentiality and security of information has become the most important inseparable aspect in information communication system. Keeping in view the same, a new approach called Visual Cryptography (VC) has been suggested by many researchers but there are some limitations with this scheme and cheating is one of the main problem among them. This paper intends to show the basis of cheating in VC in terms of cheating process, its detection methods and its prevention methods suggested by various researchers along with their merits and demerits. Finally, a good Cheating Immune Visual Cryptography Scheme (CIVCS) has been discussed which states the properties to be adopted by every Visual Cryptography scheme to make it immune to cheating attacks.
