Chemical industry enterprises are the main environmental pollutants that cause environmental problems. This is due to the production technology and the toxicity of some substances. In this paper, it is proposed to purify the gas emissions at the JSC Karpov Chemical Plant formed during the production of sodium bisulfite from sulfur dioxide by the adsorption method. As a sorption material, a modified energy waste - carbonate sludge from the chemical water treatment plant of the Naberezhnye Chelny CHPP - was used. The technological characteristics of the granular sorption material are presented. A batch adsorber with a fixed layer of granular sorption material is calculated. The modernization of the technological scheme for cleaning gas emissions from sulfur dioxide of the production line of sodium bisulfite at JSC Chemical Plant named after L.Ya. Karpov is proposed. The calculation of the prevented environmental damage and the economic effect of the modernization of the technological scheme is made.

It is proposed to purify gas emissions of industrial enterprises by the adsorption method. As a sorption material, power industry waste is used — the cuttings for chemical treatment of water of water reclamation at Kazan CHPP-1, which is formed during coagulation and liming of natural water. The chemical composition of the cuttings, its technological characteristics, the isotherm of adsorption of hydrogen sulphide cuttings, its sorption capacity and water absorption are determined. The optimum characteristics of a batch adsorber with a fixed cuttings layer are calculated. The calculation of the economic and ecological effect of the modernization of the technological scheme for cleaning gas emissions from the hydrogen sulphide line produced by the thiocol OJSC "Kazan Plant of Synthetic Rubber" is given.

Scenario Approach

On the eve of the worldwide negotiations of a new climate agreement in December 2009 in Copenhagen it is important to clearly understand what Russia can do to mitigate energy-related greenhouse gas emissions in the medium (until 2020) and in the long term (until 2050). The paper investigates this issue using modeling tools and scenario approach. It concludes that transition to the "Low-Carbon Russia" scenarios must be accomplished in 2020—2030 or sooner, not only to mitigate emissions, but to block potential energy shortages and its costliness which can hinder economic growth.
