Popis: The most important conditions for growth in processes of basic (heavy) organic synthesis (HOS) are a suitable supply of raw material and its proper utilization. The type and quality of raw material determine to a great degree not only the technology but also the economic and ecological parameters of these processes, as well as the product quality. In the petrochemical industry, feedstock costs average about 70%. The norms established for the consumption of raw material per unit of end-product are very high. In the production of synthetic rubbers and polyethylene, for example, the raw material consumption is 3 tonnes/tonne, and for nylon-6 the consumption is 7.4 tonnes/tonne. In the cost structure for HOS products, raw material accounts for 60-70%, fuel and energy 10%, labor costs 5%, amortization deductions 3-4%, and other costs 12-23%. In the light of the foregoing discussion, it can be seen that the selection of a raw material base is extremely critical in terms of long-term future growth of HOS, particularly since a period of 10-15 years may elapse between the time the first laboratory results are obtained and the actual date of completion of plant construction and the initial output of product. What are the potentialmore » sources of organic raw material that are available for HOS processes in the world and in Russia in particular? There are only four such sources: crude oil, including gas condensate; natural and associated petroleum gases; coal and oil shales; and plant biomass.« less
