This research aims to design a storage tank for 42% NaHS, a chemical reagent used in the Molybdenum flotation process for mineral processing plants. NaHS is transported by cisterns from remote storage locations far away from mining operations, and then stored in a tank for later use. From the storage tank, the reagent is extracted and mixed with water, to obtain 30% working concentration. The problem raised focuses on the lack of availability of this chemical reagent, which constitutes a limiting resource for production. Supply interruptions due to social conflicts have negative influence on the availability of this reagent. For this reason, we developed the proposal to design a new tank with higher storage capacity to improve the availability of NaHS. To carry out the design of the tank components, this research is based on the calculation fundamentals developed in the API 650 standard, and complemented with the analysis of alternative materials and sizes available in local market. In addition, from NACE Standard MR0103-2012 this research identifies the restrictions related to the corrosive effects on steel of compounds based on hydrogen sulfides, mainly stress corrosion cracking (Stress Corrosion Cracking or SCC). Then the results were verified by using finite element simulation software.
