Author Description

A preliminary feasibility study was prepared to evaluate the production of ammonium sulphate from a waste ammonia stream produced by Algoma Steel. The study evaluated the production of 6,100 tonnes per year of ammonium sulphate from a 5 wt percent ammonia solution (31,500 tonnes per year) and the production of 12,200 tonnes per year ammonium sulphate from a 10 wt. percent ammonia solution (31,500 tonnes per year). Preliminary process designs were completed for the plant configurations based on information provided by Algoma Byproducts Corp., information received from equipment vendors, and in-house data. Capital and operating cost estimates were developed from the process design information.
