1. SUMMARY

Essence of the object without uncovering of the main substance of "know how"

The scientific analysis of the production interaction with the environment allowing to estimate the direction towards improving the technological processes, which would reduce their negative influence on the environment,is possible only on the basis of system-structural analysis of the ecologization of production, particularly the chemical production.

The systematic analysis first of all of chemical products allowed to determine the main principles and methods of its ecologization basing on several concepts. Some of the stated concepts being of general technical character (recuperation, waste reclamation and resource economy), the other ones are of especially important significance to chemical production. For instance the conception of providing wasteless operation not by reclamation or resource economy, but by promoting selectivity, that is the yield rate of the target product. Finally this conception is reduced to the tendency not to try to eliminate waste,but to run the process so as to minimize its quantity.

Along with the stated above principles of complexity and system character, there should be noted such an important to modern engineering principle as flexibility. At the same time many of these methods are acting on the object to realize principles of "repeated use of resources and energy" and "maximum selectivity of the synthesis and separation", the meaning of which is sufficiently evident from their names for any field of engineering (closed-loop structure and multifunctionality of equipment, intensification).

Among them are the following: -minimizing of treatment time and the excess of one of the reagents, resulting most frequently in the increase of selectivity and in the reduction of by-products formation;

-recuperation, closed cycle of substance and energy fluxes, had shown in "idealization" of the synthesis regimes and in a significant reduction of side reactions rate;

-combining of the synthesis and separation, heterogenization, resulting in significant reduction of by-products formation by carrying the target product outside the reaction zone at the moment of its formation;

-adaptability of the technique and equipment, allowing to secure a reliable operation of the technical system through the "intrinsic" reserves of the installation, resulting in minimizing the possibility of "volley" polluted ejection out of the installation.

2.The level of realization of this concept in the industry is the testing and partial inculcating in production at the chemical plants of the FSU.

3.The main technical and economical results of realizations show that the using of this approach allows to reduce the pollution of harmful substances in tens of times with simultaneous increasing of economical characteristics of the object.

4. Desired form of exit in the western market of high technology using of our experience and concepts for consulting services at reconstruction of concrete objects.
