New Technology of MVR Na2SO4 Extraction by Thermal Process
The technology of NaCl-Na2SO4 co-production for medium and high Glauber's salt type brine is characterized by high investment,high consumption and high cost,which makes the production enterprise benefit is not good,the competitiveness is low.The higher the content of Na2SO4in brine,the more mother liquor discharged from salt system,the larger the proportion of salt-nitrate separation system,and the lower the thermal efficiency of the whole set of equipment.MVR process is combined with the local heat method to explore a new process with low consump-tion.
