An inverted tank should be installed in the phenol storage area
Thread Content
In the most recent set of drawings, the review comments suggested that inverted tanks should be installed in the phenol storage area; this is an area where I lack knowledge, so please advise. What is an inverted tank and what is its purpose? Which specification states that an inverted tank is required for the phenol storage area?
An inverted tank is a storage and transfer tank used in chemical production, primarily for holding raw materials or products to facilitate their transfer and use during processing. The function of an inverted tank is to allow the contents of the original tank to be transferred into it when it is necessary to empty or replace the substance stored in that tank, thereby ensuring the continuity and safety of production. The regulations regarding the need to install inverted tanks in phenol storage areas are generally outlined in the \"Regulations on the Safe Storage and Transportation of Hazardous Chemicals\" or related chemical engineering design standards; it is necessary to refer to local safety regulations and industry standards for specific requirements. .
It’s a backup storage tank, right? Used for backflow in case of an accident
Phenol is classified as a hazardous chemical subject to key supervision. As stipulated in the “Safety Measures and Emergency Response Principles for the First Batch of Hazardous Chemicals under Key Supervision” (Document No. ACSTG-3 [2011] 142), a dike should be constructed around areas where phenol is stored; the ground surface must be treated to prevent seepage, and inverted tanks or liquid storage ponds should be provided.
Inverted means that this storage tank is at a lower level than the lowest liquid level of ordinary storage tanks; under abnormal conditions, once the valve is opened, phenol can be transferred into the inverted tank.
