Effect of ammonium sulfate synthesis amount on industrial-scale production of fertilizer granules

Abstract

Since the economics in Thailand is established upon agriculture, the domestic fertilizer industrial is very important in supporting agricultural activities. With the business competitions being fierce, reduction of the capital cost of raw materials, which is a major cost, needs to be realized. In this aspect, Thailand's ammonium sulfate synthesis from ammonia gas and sulfuric acid liquid becomes a part that would reduce the significant amount and cost of imported ammonium sulfate granules. The option has a major impact on the economics of the plant while the synthesis process still needs further studies so as to improve its process efficiency. Therefore, this research aims at studying the relationship between the concentration of sulfuric acid used in ammonium sulfate synthesis and the granulation efficiency as well as production capacity of fertilizer granules.
