How should the cofferdam for the sulfuric acid storage tank be designed?

I’ll give you the answer in a couple of days! I have the design drawings here; let me take a look to find out what the basis for the design of the cofferdam is

The volume of the dike surrounding the sulfuric acid tank area should be no less than the volume that could leak from the largest tank in that area. After calculating the height of the dike, it should be increased further; I can’t remember the exact height. The design of the cofferdam is based on the fire protection design codes for petrochemical enterprises! The requirements for the 2008 version are now stricter! You can take a good look!

The effective volume within the dike surrounding the sulfuric acid tank area must be at least equal to the volume that could leak from the largest tank in that area; it is indeed the effective volume. The height of the dike does not exceed 1.6 meters, and is usually around 1.2 meters, with anti-corrosion measures applied on the inner side ·

Code for Fire Protection Design of Petrochemical Enterprises, 2008 Edition, 6.2.11: Tank farms shall be equipped with fire dikes. 6.2.12 The effective volume within the fire dike and partition walls shall comply with the following requirements: 1. The effective volume within the fire dike shall not be less than the volume of the largest storage tank in the tank farm. 6.2.17 Fire dikes and partition walls shall meet the following requirements: 1. They shall be able to withstand the static pressure of the liquid they contain, and shall not leak ； 2. The height of the fire dike for vertical storage tanks shall be the calculated height plus 0.2 m, but shall not be less than 1.0 m (based on the designed floor level inside the dike), and shall not exceed 2.2 m (based on the designed floor level within 3 m outside the dike) ； The height of the fire dike for horizontal storage tanks should not be less than 0.5 m (based on the designed floor level inside the dike) ； 3. The height of the dike within the vertical storage tank bank should not be less than 0.5m ； The height of the dike within a horizontal tank farm should not be less than 0.3m ； 4. The areas where pipes pass through the embankment should be tightly sealed using non-combustible materials ；

This is a lot of information. Thank you to the person who posted above; I’ve been looking for this material. Many thanks

The provisions of the 2008 edition of the Code for Fire Protection Design of Petrochemical Enterprises are aimed at the installation of flammable liquid storage tanks; dioxide storage tanks can be equipped with dikes.

Now, safety assessments are more strictly regulated; the sulfuric acid storage area is now considered a Class B liquid.

The volume of the dike surrounding the sulfuric acid tank area is 1.2 times larger than the volume of the largest tank in that area; attention should be paid to the choice of materials to ensure corrosion resistance

Is the volume of the dike surrounding the sulfuric acid tank area 1.2 times larger than the volume of the largest tank in that area? No way, does the dike really need to be that large?

The cofferdam surrounding the sulfuric acid tanks in our factory doesn’t seem to be as strict as what was mentioned above; the height is generally no more than 800 mm, and it’s mostly covered with white tiles with gaps filled using epoxy resin
