Spacing problem of spare storage tanks in tank area
Thread Content
The original storage tank spacing in the fire dike of the acetic anhydride storage tank area meets the requirements, but now a new storage tank needs to be added as a leakage emergency backup pipe and the spacing between the original storage tank and the original storage tank is insufficient. What should I do if I ask for help? Are there any corresponding regulatory requirements?
Insufficient spacing, limited storage, and can only be used for emergency purposes. Or disable it and treat it with water
The spacing between storage tank areas must comply with national standards, and there must be a certain distance from the installation area. They must not be built in the installation area. Fire-fighting facilities must be fully equipped, otherwise the impact will be serious if something goes wrong.
Petrochemical fire protection design codes and building design fire protection codes are clearly stipulated and must be enforced. There are no good methods and standards. Only by meeting this standard can we do it. Otherwise, the Work Safety Bureau will definitely give you trouble.
You can refer to the fire separation distance regulations for Class A, B, and C liquid storage tanks in the first, second, or third edition of the Chemical Process Design Manual to design the very detailed related links. http://bbs.hcbbs.com/search.php?searchid=3051&orderby=lastpost&ascdesc=desc&searchsubmit=yes
No, it should be dismantled and cannot be stored for limited use.
Now, this is how we deal with similar cases, as long as the local production safety supervision and management department approves and organizes expert review.
As leaks should be dealt with, fire separation distances should also be considered. Otherwise, in the event of a fire, the significance of the emergency tank will be lost!
Under normal circumstances, the various storage tanks in the storage tank area are connected, and each storage tank has a certain storage space. The sum of the remaining storage spaces of the storage tanks minus one from the total number of storage tanks is not less than the storage capacity of the "reduced one" storage tank. Example: There are a total of 5 storage tanks in a certain tank farm, which store the same medium. Each storage tank is connected, and the medium can be transported from any storage tank to another storage tank. However, it is necessary to ensure that each storage tank has a certain storage space and must not be full. It is also necessary to ensure that the sum of the remaining storage spaces of any four storage tanks can meet the volume requirements of not less than the volume of another storage tank. In case one of the storage tanks leaks, the other storage tanks can meet the acceptance conditions. In this way, there is no separate leakage emergency tank in the tank farm, but all are commonly known as storage tanks. That is to say, there is no distance problem between the emergency tank and other storage tanks, but the pure distance between each storage tank in the tank farm. Then the distance between each storage tank must comply with the requirements of the "Petrochemical Regulations" and "Construction Regulations". Personal opinions, welcome to in-depth discussion
If it is a separate emergency backup slot, is there any relevant basis?
The spare tank must also meet the requirements for storage tank spacing in construction regulations and petroleum regulations. Whether it is an accident tank or a pressure relief tank, this should be clear. Taking a step back, what should you do if you use this tank to fill materials? As long as there is a tank, there will definitely be materials.
Hmm~~I agree with you upstairs~~ Whether it is called a spare tank or an accident tank, these are the names given by the company itself. Its ultimate purpose is to store materials, which means that it is ultimately a storage tank. Since it is a storage tank, there is no doubt that it must be set up in accordance with the relevant requirements in the specification.
