Basic Contractor Iran science & technology university – Dr. Kasiri Description Identifier Code :77213092Contract Code77/090Ammonia sulphate is used as a chemical fertilizer and it is an important resource of nutritious sulphur and nitrogen for plants. In this research the feasibility study of its production in the complex have been evaluated by using Gypsum (Ca 2 O 4 ) and ammonia and also sulphuric acid and ammonia. Because of high radioactive radiation, process complexity, high steam consuming and less quality of the production, using Gypsum was not economical. The considerations of using sulphuric acid and ammonia showed that if the fertilizer-selling price were government prescribed, capitalizing is not economical. So it is suggested to have a shared capitalization with a private section
