According to the regulations, should a 20-cubic-meter hydrochloric acid storage tank and a 20-cubic-meter liquid alkali storage tank be classified as a tank farm? What are the required safety distances between the hydrochloric acid storage tank and the liquid alkali storage tank according to the specifications?
Yes, according to the specifications, a 20-cubic-meter hydrochloric acid storage tank and a 20-cubic-meter liquid alkali storage tank must be designated as a tank farm. As for the issue of safety distances, since it relates to the storage of chemicals, specific regulations may vary from place to place; generally, it is necessary to follow the \"Regulations on the Safety Management of Hazardous Chemicals\" and relevant industry standards. For this matter, it is recommended that you consult a professional safety assessment agency or the local safety regulatory authorities, as they can provide accurate advice based on the actual circumstances. .
For storage tanks of categories A, B, and C, there are requirements regarding fire separation distances and pump distances; in such cases access to the tank area is necessary. However, this is different if it refers to intermediate tanks (transfer tanks) used in the manufacturing process, or if the requirements of clause 5.5.1 are met. Hydrochloric acid and liquid caustic belong to Category V; there are no specific requirements for them. Currently, raw material tanks are generally located within the tank area, with the exception of intermediate tanks (transfer tanks). It is recommended to follow the design specifications.

The systems used in the past had no special requirements; I’ve seen tanks installed directly on top of buildings. The system was installed in 2008; the designs were prepared by the design institute. The distance between the tanks is 6 meters, and no cofferdam was used (there are circular collection ditches around them). Things are stricter now; even ammonia tanks with a capacity of 20 cubic meters require the installation of cofferdams. It is recommended to consult designers and suppliers.
According to the petrochemical and refining regulations, Class D and E substances have no volume requirements
