• impurities in raw materials, i.e. components that are not used in this process to produce the finished product;
• incompleteness of the process, the balance of useful product in the feed;
• adverse reactions, leading to the formation of unnecessary materials.
Management of complex and integrated use of raw materials reduces the amount of underutilized substances; increases the range of finished products, to produce new products from that part of the raw materials, which previously went to waste.
Integrated use of valuable constituents of raw materials is possible only at a certain stage of development according to the rates of technological progress within the organisation.
The main specific feature of the complex production lies in the fact that the high economic efficiency of the complex use of raw materials in general is not indicative of the efficiency of extraction of each of the recoverable valuable components. High efficiency preparation of several or even one of the components may overlap the losses from the extraction of the remaining components of raw materials. On the other hand rejection of extracting valuable components of complex materials, in some cases can translate into high production unprofitability. It is therefore necessary not only to the overall assessment of complex use of raw materials in general, but a differentiated assessment of the economic efficiency of obtaining each of the valuable components of raw materials separately, i.e. definition of a rational range of valuable components of the raw materials to be retrieved or recovered.
Recommended method of estimating the cost-effectiveness of integrated management, the essence of which is as follows:
a) economic feasibility of using the boundary of each of the valuable components of raw materials separately with its complex processing is determined from the return only direct additional costs associated with the organization of component extraction, excluding any portion of indirect costs;
b) the economic efficiency of integrated multi-component material is generally defined in terms of return on total direct and indirect costs of production and comprehensive processing of raw materials, taking into account only those components extraction which are economically feasible in accordance with the principle set forth in paragraph "a";
c) the appropriateness of the complex use of raw materials is considered to be economically viable (proven) only if all of the terms "a" and "b" are fulfilled.
Some of the directions of Oil Gas Chemical Company, which use waste of productions are:
Recast of waste oil products:
– Industrial oil waste (cut)
– Waste gas stations and oil depots
– Mixtures of used petroleum products (oils and fuels with high content of tar)
– The spent drilling mud, sludge from the extraction of hydrocarbon components can be used as a feedstock in the process of hydro cracking in oil refineries to produce commodity petroleum products.
Deep Recycling of thermoplastic and thermoset synthetic polymer.
Recycling of waste plastics:
– Processing to produce high-purity granular plastics
– Processing to produce new polymer materials;
– Thermal recycling of polymer wastes to produce useful products of non-polymer nature
Waste treatment of reagents (crumb rubber and other waste rubber products):
