Conclusions

Devising waste-free technology for the process of cleaning up exhaust air from man-made fibre plants from hydrogen sulfide is tied in with the development of methods for utilization of the main oxidation products of the absorbed hydrogen sulfide — finely dispersed sulfur and sodium thiosulfate.

A process for the preparation of an acarofungicide based on finely divided sulfur has been developed and realized in industry; this is a valuable product which is needed to fulfill the the goals of the Food Program. A process has been developed for the preparation of sodium thiosulfate from absorber solutions in the alkaline-catalytic method of freeing exhaust gases from hydrogen sulfide.
