Abstract

Viscose products are produced from CS2 that is produced continuously and immediately in a CS2 plant linked to the viscose plant. The waste gases from the CS2 plant and the vented air from the viscose plant are treated together so that the gaseous sulphur compounds contained in them are converted into H2SO4 which is then recycled for use in the viscose plant.
