Potassium sulphate (K2SO4), a.k.a. sulphate of potash (SOP), is an important potassium compound withx000D
application as fertilizer. The world SOP market is about 4,000,000 tons per annum, Canada being the largestx000D
producing country, and is the second largest tonnage potassium compound produced. SOP is preferred overx000D
potash (KCl, a.k.a. MOP) as fertilizer for some species that cannot tolerate chloride (Cl) of potash, e.g. mostx000D
fruits and vegetables. SOP is also preferred over potash for being a sulphur rich fertilizer.x000D
This project focuses on the studying of the feasibility of the SOP production from 2 different sources:x000D
1- from schoenite, K2Mg(SO4)2.6H2O mineral, a potassium and magnesium double sulphate salt which isx000D
commonly produced in solar pond operations.x000D
2- From industrial SO2 flue gases, which would will provide an important environmental benefit. SO2 gasx000D
release results in acidic rain (a significant environmental issue), so if the proposed research is successful,x000D
industry could use the new process to convert a problematic pollutant into a useful fertilizer.
