Popis: An analysis has been made of existing methods of cleaning up low-concentration gas discharges from viscose manufacturing from hydrogen sulfide and carbon disulfide. It has been found that the most effective method of purification in that which uses ion-exchange and carbon materials, and which requires developing apparatus (filters) of large unit capacity. For a number of plants, it is recommended to use the the thermal method of cleaning up low-concentration discharges from hydrogen sulfide and carbon disulfide; this is characterized by simplicity and low economic costs. A radical solution to the problem of protecting the air reservoir from contaminants is the development of low-waste technology including utilization of gaseous discharges. Low-waste technology in the manufacture of viscose fibre is being developed in the “Khimvolokno” NPO and will be realized in the very near future in one of the sub-branch plants.
