Dec 31, 1995 Conversion of FGD- gypsum to ammonium sulfate was tested at 60-70{degree}C for 5-6 hr. Yield up to 82% and purity up to 95% were achieved for the ammonium sulfate production. During this quarter, more bench-scale experiments including a mass balance analysis were conducted; a yield up to 83% and up to 99% purity were achieved.

About this site

A continuous countercurrent flow process for converting FGD gypsum to ammonium sulfate and calcium carbonate including countercurrent flows with internal recycle of liquids to maximize the purity of reaction products while minimizing reaction times, and further include embodiments of the process that provide a yield of both ammonium sulfate and calcium carbonate to be 97 to 100%, and

About this site

Dec 31, 1995 The scrubber, a Chiyoda Thoroughbred 121 FGD, produced a filter cake product contains 98.36% gypsum (CaSO{sub 4}.2H{sub 2}O), and less than 0.01% calcium sulfate (CaSO{sub 3}). Conversion of FGD-gypsum to ammonium sulfate were tested at temperatures between 60 to 70{degrees}C for a duration of five to six hours.

About this site

ammonium sulfate is manufactured from gypsum by a continuous process in which an aqueous flow of material is continously recycled along a predetermined closed circuit defined by a conduit and a wider vallel connected in series. a fresh aqueous gypsum slurry comprising a dispersion of finely divided gypsum in an ammonium sulfate solution is continuously introduced into the flowing material and
