Abstract: Concentrated sulfuric acid is strongly oxidizing, highly corrosive and highly toxic. This paper introduces the design standards applicable for concentrated sulfuric acid tank, analyzes the feasibility of using carbon steel as the material of concentrated sulfuric acid tank body, and proposes some requirements for the structural form of connections located on tank wall and tank roof. The advantages and disadvantages of various tracing forms for concentrated sulfuric acid tank as well as the corresponding safety precautions are discussed, and a reasonable tracing form is proposed. The additional requirements and the criterion of acceptability for nondestructive examination of concentrated sulfuric acid tank storing high toxic medium are defined, and the design of ladder platform for concentrated sulfuric acid tank and the safety considerations during the use of tank are discussed

Key words: concentrated sulfuric acid tank, design standard, examination requirements, safety considerations
