Research of Methods and Practice of Sulfur Utilisation in Russia

The report is devoted to research of methods and practice of sulfur utilisation in Russia. The report is composed of 6 Chapters, contains 91 pages, including 2 Figures, 15 Tables and Appendix.

Methodologically, the work was implemented in 2 stages – "desk" studies and "field" activity. At the first stage, we analysed many information sources, first of all, data of state bodies. Besides, we used data of companies, own database, information from mass-media and internet.

At the second stage, the summarized and analysed data were verified and corrected by the way of telephone interviews with specialists of companies, describes in the report.

The first Chapter of the report presents data on world experience in sulfur utilisation.

The second Chapter of the report is devoted to available methods of sulfur utilisation.

The third Chapter of the report presents data on methods of sulfur storage.

The fourth Chapter presents data on Russian organizations, involved in sulfur utilisation.

The fifth Chapter of the report describes enterprise, realizing (planning to introduce) methods of sulfur utilisation.

The sixth Chapter of the report gives forecast of introducing methods of sulfur utilisation in Russia.

The Appendix presents addresses and contact information on companies, involved in sulfur utilisation in Russia.
